#MERS #Coronavirus Oman Confirmed Case, Contacts Are Screened
November 2, 2013
Coronavirus infection — By Conrad Prabhu — MUSCAT — Health authorities say they have begun screening family members, relatives, acquaintances and other individuals who may have come into contact with the patient diagnosed last week as Oman’s first confirmed case of MERS-Coronavirus (MERS-CoV). The objective, according to officials, is to make sure that none of these contacts may have been exposed to the deadly virus behind a simmering global outbreak that has so far claimed around 62 lives worldwide, chiefly in Saudi Arabia. Also as part of the screening effort, authorities are working to track down healthcare workers who may have first attended to the 68-year-old patient at a local health centre before he was transferred to the referral hospital at Nizwa.
Any contacts will be observed for any symptoms associated with the virus for a period of two weeks before they receive the all-clear, it is learnt. At the weekend, officials overseeing the investigation and management of Oman’s maiden coronavirus case travelled to Nizwa to ensure that well-established case detection, reporting and management procedures related to suspected coronavirus cases are stringently implemented in the health institutions concerned. Those procedures were formulated and rolled out earlier this year as part of preparedness plans formulated by the Health Ministry in anticipation of the odd case of coronavirus surfacing in the Sultanate. According to officials, the sensitisation of both public and private sector healthcare staff to the potential threat posed by the coronavirus began at the start of this year, when cases began surfacing around the Middle East and parts of Europe.
This sensitisation effort was achieved through regular awareness workshops and circulars that sought to enlighten frontline healthcare workers, as well as lab staff, about the precautions to be taken when faced with a suspect case. Meanwhile, the overall condition of the elderly patient, who is currently on a ventilator, is described as stable. A possible transfer to a suitably equipped tertiary hospital is among a number of options being weighed as part of the patient’s ongoing treatment, it is learnt.

#MERS #Coronavirus France Seven Suspected, 6 From Same Family, Some Hospitalized
November 2, 2013
Seven people were hospitalized Friday at the Purpan Hospital in Toulouse for a hint of coronavirus . Six of them belong to the same family . The seventh is a 73 year old woman .
Six members of the same familySix members of the same family were hospitalized Friday night, grandparents , parents and two children . All returned on October 28, a trip to Saudi Arabia. But only grandparents have respiratory symptoms and fever over 38 degrees . The father has his flu-like symptoms . They were admitted to the Infectious Diseases Hospital Purpan and samples were taken to determine if they are infected with novel coronavirus coronavirus now called the Middle East (MERS -CoV) respiratory syndrome. According to Dominique Soulie , the communications manager of Toulouse University Hospital , the two children and their mother who showed no clinical signs were discharged home on Saturday with strict instructions isolation . Their father and grandparents remain under observation until test results expected for Sunday night at the earliest , but they have " no clinical signs of severity ."
A seventh person hospitalizedAnother person was also hospitalized for the same suspicion Purpan coronavirus . It is a 73 year old woman who also returned from a pilgrimage to Mecca . In his case, according to Dr. Raynaud of the Regional Health Agency (ARS) , analyzes invalidated the hypothesis cornavirus but remains under observation.
Two cases in France to dateOnly two confirmed cases of coronavirus were previously identified in France . The first patient died on May 28, 2013 when he was hospitalized in intensive care in Lille. The second patient, who had also been quarantined, today is no longer carrying the virus by the medical team of the hospital in Lille. He remains hospitalized , according to the Ministry of Health. He shared a room and the first patient and was a confirmed transmission of the virus between humans case .
A hotlineThe Ministry of Health has set up a hotline , free contacted from Monday to Saturday from 9 am to 19 pm 0800 13 00 00 . It is for people who, after a trip to the Arabian Peninsula , would present respiratory symptoms ( cough, shortness of breath and difficulty breathing ... ) and fever within 14 days after the return or close contact with a person infected with this new virus.The disease causes pneumonia and renal failure may also occur primarily by gastrointestinal symptoms ( diarrhée. ..) .
145 cases of coronavirus in the worldIn his latest report of 29 October 2013, the World Health Organization (WHO) reported a total of 145 cases worldwide, including 62 deaths since September 2012. WHO does not recommend travel restrictions with the countries concerned .The new virus responsible for the disease , designated by the WHO as the respiratory syndrome in the Middle East (Middle East Respiratory Syndrome , MERS) , belongs to the same family as the head of the severe acute respiratory syndrome virus (SARS ), which had is nearly 800 deaths worldwide in 2003.

WHO Middle East respiratory syndrome coronavirus (MERS-CoV) - update 10/29/13
31 October 2013 -
WHO has been informed of an additional four
laboratory-confirmed cases of infection with Middle East respiratory
syndrome coronavirus (MERS-CoV). These include the first
laboratory-confirmed case from Oman and three additional
laboratory-confirmed cases from Saudi Arabia.
The patient in Oman is a 68-year-old man from Al Dahkliya region who became ill on 26 October 2013 and was hospitalized on 28 October 2013. Preliminary epidemiological investigations revealed that he did not recently travel outside the country. However, investigations are currently ongoing to determine what exposures might be responsible for his infection
Of the three patients including one death reported from the Eastern Region in Saudi Arabia, one is a woman and two are men. The three patients, one of whom is a health care worker, had underlying medical conditions. Their ages range from 49 to 83 years old. All three patients reported having no contact with animals prior to their illness, while one patient was reported to have been in contact with a previously laboratory-confirmed case.

Study: SARS Virus Originated From Bats In China
By Esther Tanquintic-Misa | November 1, 2013 9:26 AM EST
Excerpt (editing is mine)
Scientists from Australia, the U.S. and China Thursday confirmed that the severe acute respiratory syndrome (SARS) virus, which killed more than 750 people worldwide in 2002 and 2003, originated from horseshoe bats in China.
-snip-
Scientists Thursday said it was the first time the live virus was successfully isolated from bats to ultimately confirm that they are the virus' forerunner.
"The results will help governments design more effective prevention strategies for SARS and similar epidemics," the statement said.
"Our results - in addition to the recent demonstration of MERS-CoV in a Saudi Arabian bat, and of bat CoVs closely related to MERS-CoV in China, Africa, Europe and North America - suggest that bat coronaviruses remain a substantial global threat to public health."
"Now that animals, including bats, and humans live closer together as our population expands globally, the opportunity for direct transmission of these dangerous viruses becomes more and more of an issue," Crameri stressed.

MERS-CoV antibodies not found in children in 2010-11 or adults from 2012
From Virology Down Under Blog:
October 27, 2013
Gierer and colleagues from the German primate center and the University of Dammam in Saudi Arabia, have presented the findings of their study of antibodies to the Middle East respiratory syndrome coronavirus (MERS-CoV).
The publication, in Emerging Infectious Diseases (ahead of print - you can find it here, at least until it's other link here starts working), measured the antibodies capable of blocking infection by MERS-CoV, called "neutralising antibodies" with a method they have described before. The assay was not validated with multiple MERS-CoV-positive patient sera, but appeared specific in the testing completed.
Patient samples from the area served by King Fahd Hospital were obtained from:

Patient samples from the area served by King Fahd Hospital were obtained from:
- Children (158 sera, 77 female, mean age 12 months) admitted to hospital with lower respiratory tract infections during 12-months form May 2010.
- Adult (110 plasma samples, all males, mean age 28-years, upper limit of 52-years) blood donors
No sera or plasma had neutralising MERS-CoV antibodies.
The authors conclude that <2.3% of children and <3.3% pod adults were seropositive though, because that accounts for the upper limit of the confidence intervals. They also note that their sampling of hospitalized children couldhave missed an antibody response (because it takes time to develop) if they had only just been admitted to hospital for MERS-CoV.

Study: Uncommon #H5N1 mutations may transmit in mammals
Excerpt
CIDRAP
CIDRAP
A study assessing H5N1 avian flu mutations as the virus spreads in ferrets found that mutations that were present in as few as 5.9% of the viruses infecting one ferret could be transmitted to another, according to data published this week in Nature Communications.
US and Japanese researchers, including Yoshihiro Kawaoka, DVM, PhD, of the University of Wisconsin, used data from transmission studies already conducted by Kawaoka in 2011 on engineered H5N1 strains. Publication of that controversial work was originally halted but later allowed by US biosecurity experts.
The team used deep sequencing to identify genetic mutations that happened as the virus replicated in and transmitted between ferrets. They found that during transmission natural selection acts strongly on hemagglutinin (HA), the protein the virus uses to attach to host cells.
They found that within-host genetic diversity in HA increases during replication but is dramatically reduced upon transmission via respiratory droplets—to only one or two distinct HA segments, a small portion of the viral genome.
However, the discovery that mutations present in only 5.9% of the viruses infecting one ferret could be transmitted to another suggests that even rare mutations could be transmitted if they have an evolutionary advantage, according to a Science Daily story on the study.
"Fully avian viruses may act differently in nature," said lead author Thomas Friedrich, PhD, from the University of Wisconsin. "But the data suggest to us that it wouldn't take many viruses from a chicken to infect a person, if the right mutations were there—even if they were a tiny minority of the overall virus population."

WHO: Human infection with avian influenza A(H7N9) virus – update October 24, 2013 #H7N9
24 OCTOBER 2013 - The National Health and Family Planning Commission, China notified WHO of a new laboratory-confirmed case of human infection with avian influenza A(H7N9) virus.
The patient is a 67-year-old man from Zhejiang Province. He is a farmer, and has had contact with live poultry. He became ill on 16 October 2013, was admitted to a local township hospital on 18 October 2013, and was transferred to another hospital on 21 October 2013 as his condition deteriorated. He is currently in a critical condition.
To date, WHO has been informed of a total of 137 laboratory-confirmed human cases with avian influenza A(H7N9) virus infection including 45 deaths. Currently, four patients are hospitalized and 88 have been discharged. So far, there is no evidence of sustainable human-to-human transmission.
The Chinese government has taken the following surveillance and control measures:
- strengthening of epidemic surveillance and analysis;
- deployment of medical treatment;
- conducting public risk communication and information dissemination;
- strengthening international cooperation and exchanges; and
- is continuing to carry out scientific research.
WHO does not advise special screening at points of entry with regard to this event, nor does it currently recommend any travel or trade restrictions.
Nearly 1m pilgrims received medical aid this Haj #MERS #Coronavirus
October 27, 2013
RIYADH — Nearly half of the pilgrims who came from abroad for this year's Haj received various kinds of healthcare services during their stay in the holy cities, according to the Kingdom's deputy minister of health.
"A total of 997,379 pilgrims from various nationalities have received healthcare services of varying degrees," Ziad Maimish said while addressing the fourth Islamic Health Ministers Conference currently under way in the Indonesian capital Jakarta.
Maimish explained how the Kingdom was able to successfully organize an epidemic-free Haj at a time the entire world was apprehensive of a possible Middle East Respiratory Syndrome Coronavirus (MERS-CoV) outbreak during the annual pilgrimage.
Maimish cited a number of measures put in place by the Saudi health authorities to prevent any outbreak of contagious diseases among pilgrims.
These measures included policies formulated by the National Committee for Infectious Diseases on prevention and dealing with infections, levels of emergency preparedness and application of necessary measures to intensify early epidemiological surveillance, including special procedures for MERS-CoV.
In addition, the Health Ministry made available laboratory equipment and materials necessary to conduct quick tests and analysis for all viruses, vectors and pathogens. It also ensured the continuation of developing health centers in the holy cities of Makkah and Madinah.
The authorities also secured most modern diagnostic and therapeutic devices for ambulatory services to enable fast field treatment or hospital transfers. This was in addition to developing speedy ambulance tracking and directing services, Maimish said.
To face the MERS-CoV challenge, he said, the Saudi authorities installed a new laboratory at Mina Wadi Hospital, which is at the heart of the pilgrimage zone, for rapid conduct of tests for suspected cases and getting test results within a matter of hours.
This was in addition to existing laboratory facilities in Jeddah and Madinah.
Some 22,500 health workers from across the Kingdom arrived to staff 25 hospitals with 5,250 beds and 141 health centers at four main pilgrim centers.
As part of this year's health guidelines for incoming pilgrims, the National Scientific Committee for Infectious Diseases recommended that people older than 65, children, pregnant women and those with underlying conditions should postpone their pilgrimage due to the MERS-CoV risk.
Maimish pointed out that the health authorities conducted random checks of pilgrims at air, land and sea ports of entry to monitor compliance with the preventive health measures for Haj. More than 2,000 healthcare professionals were deployed at various entry points to carry out this task.
As many as 613,050 external pilgrims were vaccinated at the entry points — 430,500 against polio and 182,550 against meningitis, Maimish said.
He added that in addition to detailed investigations of every suspected case, case-control studies for index cases and intensive follow-up of contacts with serological testing to improve understanding of the critical features of MERS-CoV infection were carried out.
This year’s Haj was termed critical by the World Health Organization (WHO) due to the looming MERS virus that has claimed at least 58 lives — mostly in Saudi Arabia — since it first emerged in 2012.
For the fourth consecutive year, WHO has been invited by the Ministry of Health to observe and to provide any required technical assistance during the Haj.

WHO Middle East respiratory syndrome coronavirus (MERS-CoV) - update October 24, 2013
24 October 2013
WHO has been informed of two laboratory-confirmed cases of Middle East respiratory syndrome coronavirus (MERS-CoV) infection in Saudi Arabia on 18 and 19 October 2013, and three laboratory-confirmed cases on 18 September 2013.
Of the five laboratory-confirmed cases, two died. The ages of the five patients range from 35 to 83 years old; four men and one woman; two from Medinah and three Riyadh. Four patients had underlying medical conditions. Two patients reported having no contact with a laboratory-confirmed case or with animals prior to becoming ill.
Globally, from September 2012 to date, WHO has been informed of a total of 144 laboratory-confirmed cases of infection with MERS-CoV, including 62 deaths.
Based on the current situation and available information, WHO encourages all Member States to continue their surveillance for severe acute respiratory infections (SARI) and to carefully review any unusual patterns.
Health care providers are advised to maintain vigilance. Recent travellers returning from the Middle East who develop SARI should be tested for MERS-CoV as advised in the current surveillance recommendations.
Patients diagnosed and reported to date have had respiratory disease as their primary illness. Diarrhoea is commonly reported among the patients and severe complications include renal failure and acute respiratory distress syndrome (ARDS) with shock. It is possible that severely immunocompromised patients can present with atypical signs and symptoms.
Health care facilities are reminded of the importance of systematic implementation of infection prevention and control (IPC). Health care facilities that provide care for patients suspected or confirmed with MERS-CoV infection should take appropriate measures to decrease the risk of transmission of the virus to other patients, health care workers and visitors.
All Member States are reminded to promptly assess and notify WHO of any new case of infection with MERS-CoV, along with information about potential exposures that may have resulted in infection and a description of the clinical course. Investigation into the source of exposure should promptly be initiated to identify the mode of exposure, so that further transmission of the virus can be prevented.
WHO does not advise special screening at points of entry with regard to this event nor does it currently recommend the application of any travel or trade restrictions.
WHO has convened an Emergency Committee under the International Health Regulations (IHR) to advise the Director-General on the status of the current situation. The Emergency Committee, which comprises international experts from all WHO Regions, unanimously advised that, with the information now available, and using a risk-assessment approach, the conditions for a Public Health Emergency of International Concern (PHEIC) have not at present been met.

#MERS #Coronavirus Saudi Arabia Dr. Memish: Pilgrims' Health Status Is Reassuring...No Epidemic Cases Detected
16 October 2013
Speaking of the ways of dealing with any Coronavirus case, Allah
forbid, Dr. Memish said that the Ministry has a several-phase plan to
face these potential cases; such a plan starts with diagnosing the case
and testing the health practitioners, with isolation of the positive
cases in rooms allocated for this purpose and examination of the close
people, pointing out that the laboratories have already been equipped
with equipments.
http://www.moh.gov.sa/en/Ministry/MediaCenter/News/Pages/news-2013-10-16-005.aspx
The
Deputy Minister for Public Health and the Head of the Hajj Curative
Medicine Committee, Dr. Ziad bin Ahmed Memish, said that the health
situation is reassuring, and there are no epidemic diseases among
pilgrims thankfully so far.
In addition, the Ministry of Health (MOH) has not yet recorded any
cases of meningitis or food poisoning in the Holy Sites, expressing his
hope that the health situation continues as it is now so that the
pilgrimage season passes safely without recording any epidemic or
quarantine diseases.
Within the same vein, Dr. Memish announced at a news conference
held on Tuesday that the Kingdom has updated its health requirements
this year after following up and monitoring the global heath situation
throughout the year in collaboration with the World Health Organization
(WHO) and the research and diseases centers in America and Europe.
In addition, Dr. Memish underscored that the MOH has launched a
huge awareness campaign targeting the countries from which the pilgrims
come, adding that such campaigns focus on the pilgrimage ports and
areas; contributing significantly to obtaining such good fruits so far.
Within the same vein, Dr. Memish pointed out that based upon the
MOH’s accumulated experiences and study of cases with Coronavirus, the
Ministry advices the elderly people, patients with chronic diseases,
pregnant women and children to postpone the performance of Hajj, after
founding that 75% of the Coronavirus deaths which are recorded locally
and globally occur amidst such segments of people.
Moreover, Dr. Memish underscored that the Ministry is currently
working on preparation and implementation of 10 studies expected to help
in dealing with the pilgrims and contributing to the development of
solutions to any emergent health problems, especially the infectious and
epidemic diseases which attract the attention of the Ministry, noting
that some of such studies are related to Coronavirus while others are
related to meningitis and the other viruses widely spread in the world.
Furthermore, Dr. Memish mentioned that the study teams have ended
the first phase, during which random samples were taken from pilgrims
coming from abroad, noting that the second phase will kick off on
Thursday 12/12/1434H (corresponding to 17/10/2013) by taking samples
from the pilgrims before their departure to make sure that they are free
from diseases and to recognize their health status.

Flu virus wipes out immune system’s first responders to establish infection
Hat-tip: Flutrackers.com
October 19, 2013
CAMBRIDGE, Mass. – Revealing influenza’s truly insidious nature, Whitehead Institute scientists have discovered that the virus is able to infect its host by first killing off the cells of the immune system that are actually best equipped to neutralize the virus.
Confronted with a harmful virus, the immune system works to generate cells capable of producing antibodies perfectly suited to bind and disarm the hostile invader. These virus-specific B cells proliferate, secreting the antibodies that slow and eventually eradicate the virus. A population of these cells retains the information needed to neutralize the virus and takes up residence in the lung to ward off secondary infection from re-exposure to the virus via inhalation.
On the surface of these so-called memory B cells are high-affinity virus-specific receptors that bind virus particles to reduce viral spread. While such cells should serve at the body’s first line of defense, it turns out that flu virus exploits the specificity of the cells’ receptors, using them to gain entry, disrupt antibody production, and ultimately kill the cells. By dispatching its enemies in this fashion, the virus is able to replicate efficiently before the immune system can mount a second wave of defense. This seemingly counter-intuitive pathway to infection is described this week in the journal Nature.
“We can now add this to the growing list of ways that the flu virus has to establish infection,” says Joseph Ashour, a co-author of the Nature paper and a postdoctoral researcher in the lab of Whitehead Member Hidde Ploegh.
“This is how the virus gains a foothold,” adds Ploegh lab postdoc Stephanie Dougan, also a co-author of the study. “The virus targets memory cells in the lung, which allows infection to be established—even if the immune system has seen this flu before.”

#MERS #Coronavirus WHO Update October 18, 2013
Middle East respiratory syndrome coronavirus (MERS-CoV) - update
18 October 2013 - WHO has been informed of an additional laboratory-confirmed cases of Middle East respiratory syndrome coronavirus (MERS-CoV) infection in Qatar.
The patient is a 61-year-old man with underlying medical conditions who was admitted to a hospital on 11 October 2013. He is currently hospitalized and is in a stable condition. The patient was tested positive for MERS-CoV infection in Qatar and was confirmed by the reference laboratory of Public Health England yesterday.
Preliminary investigations revealed that the patient had not travelled outside Qatar in the two weeks prior to becoming ill. The patient owns a farm and has had significant contact with the animals, including camels, sheep and hens. Some of the animals in his farm have been tested and were negative for MERS-CoV. Further investigations into the case and the animals in the farm are ongoing.
Globally, from September 2012 to date, WHO has been informed of a total of 139 laboratory-confirmed cases of infection with MERS-CoV, including 60 deaths.
Based on the current situation and available information, WHO encourages all Member States to continue their surveillance for severe acute respiratory infections (SARI) and to carefully review any unusual patterns.
Health care providers are advised to maintain vigilance. Recent travellers returning from the Middle East who develop SARI should be tested for MERS-CoV as advised in the current surveillance recommendations.
Specimens from patients’ lower respiratory tracts should be obtained for diagnosis where possible. Clinicians are reminded that MERS-CoV infection should be considered even with atypical signs and symptoms, such as diarrhoea, in patients who are immunocompromised.
Health care facilities are reminded of the importance of systematic implementation of infection prevention and control (IPC). Health care facilities that provide care for patients suspected or confirmed with MERS-CoV infection should take appropriate measures to decrease the risk of transmission of the virus to other patients, health care workers and visitors.
All Member States are reminded to promptly assess and notify WHO of any new case of infection with MERS-CoV, along with information about potential exposures that may have resulted in infection and a description of the clinical course. Investigation into the source of exposure should promptly be initiated to identify the mode of exposure, so that further transmission of the virus can be prevented.

INFLUENZA (58): WORLD HEALTH ORGANIZATION GLOBAL UPDATE NO.196
A ProMED-mail post
Date: Mon 14 Oct 2013
Source: WHO surveillance & monitoring update 196 [edited]
http://www.who.int/influenza/surveillance_monitoring/updates/2013_10_14_surveillance_update_196.pdf
Influenza Update No. 196 - 14 Oct 2013
--------------------------------------
Summary
Although in many European countries influenza-like illness activity started to increase, influenza activity in the northern hemisphere temperate zones remained at inter-seasonal levels.
In most regions of tropical Asia, influenza activity was at a low level, with the exception of Hong Kong Special Administrative Region, China, where influenza transmission increased due to influenza A(H3N2).
In the Caribbean region of Central America and tropical South American countries, cases of influenza decreased, while acute respiratory illness remained stable in the Caribbean and Central America. Respiratory syncytial virus (RSV) predominated, but the RSV activity remained within expected seasonal levels.
Influenza activity peaked in the temperate countries of South America and in South Africa in late June 2013. Temperate South American countries reported acute respiratory disease activity within expected seasonal levels, and RSV activity largely declined.
In Australia and New Zealand, numbers of influenza viruses detected and rates of influenza-like illness seemed to have peaked. Co-circulation of influenza A(H1N1)pdm09, A(H3N2) and B viruses was reported in both countries.
Additional and updated information on non-seasonal influenza viruses can be found at: http://who.int/influenza/human_animal_interface/HAI_Risk_Assessment/en/inde.
Countries in the temperate zone of the northern hemisphere
--------------------------------
North America
Overall influenza activity in North America remained at low levels throughout the region. In Canada and the United States of America, influenza activity remained at interseasonal levels. In Mexico, influenza activity remained low after a period of 2 months (July-August 2013) with higher influenza activity.
Europe
Influenza activity in Europe remained at interseasonal levels. None of the specimens collected from sentinel sites between 10-22 Sep 2013 tested positive for influenza. However, many countries started reporting increased consultation rates for influenza-like illness (ILI) and acute respiratory infection (ARI).
Northern Africa and the Western Asia region
Influenza activity was low in the Northern Africa and western Asia regions. Only Qatar reported influenza activity, mainly influenza A virus (not subtyped), since the end of August 2013.
Northern Asia
Influenza activity in the temperate region of Asia remained at interseasonal levels since late May 2013. In Mongolia, clinical activity started to increase since mid-August 2013, but no influenza viruses were detected in this period.
Countries in the tropical zone
-----------------------
Tropical countries of the Americas/Central America and the Caribbean:
Overall influenza activity in the Caribbean and Central America was at a low level throughout the region. Decreasing numbers of influenza A virus have been seen throughout the region, but influenza transmission had largely come to an end in the last few weeks in these countries. Co-circulation of influenza A(H3N2) and influenza B viruses were reported, and RSV predominated among respiratory viruses in Costa Rica, El Salvador, Nicaragua, and Panama.
In tropical South America, respiratory virus activity continued decreasing following a period of high influenza activity in July and August 2013. In Colombia, the proportions of outpatient visits, hospitalizations, and ICU admissions were similar to reports for the same period in previous years. In Venezuela, ARI and pneumonia levels were reported within the expected values for the time of year. In Ecuador, the number of positive influenza samples steadily decreased since its influenza peak in August 2013. In Peru, reports of ARI in children under 5 years of age have been increasing since July 2013, but were consistent with levels from previous years. In the Plurinational State of Bolivia, the proportion of SARI-related hospitalizations were reported as elevated compared to the data from the same period last year [2012], and laboratory data from CENETROP [National Center of Tropical and Infectious Diseases] in Santa Cruz showed that of 182 SARI samples analyzed in the beginning of October 2013, 33 percent were positive for a respiratory virus (a 9 percent increase from the previous week). Brazil showed a continuing decline in the number of positive influenza samples since July 2013, and among recent positive samples, influenza A un-typed and influenza B viruses were detected.
Central African tropical region
Cote d'Ivoire, Ghana, and Kenya reported circulating influenza viruses. In Cote d'Ivoire and Ghana, influenza B and A(H3N2) were the predominant viruses detected. Kenya reported low influenza activity due to both influenza A(H3N2) and influenza B viruses.
Tropical Asia
Influenza transmission in southern and Southeast Asia was low in most countries. Both influenza A(H1N1)pdm09 and A(H3N2) viruses were reported in this area. Since early July 2013, an increase in influenza transmission was seen in Hong Kong Special Administrative Region (SAR), China. The influenza transmission in Hong Kong SAR was predominated by influenza A(H3N2) virus. This increased transmission was also seen in the influenza associated hospital rates in this region; mainly the rates among 0-4-year-old patients increased over the past month. In the south of China, influenza activity remained at an interseasonal level. However, the number of influenza virus detections has been higher in this year's [2013] interseasonal period compared to the previous year.
Countries in the temperate zone of the southern hemisphere
-----------------------------------
Temperate countries of South America
In the temperate countries of South America, ARI activity was reported at expected levels for the time of year, and RSV continued to be the most common respiratory virus detected in Argentina and Chile, although cases had largely decreased. In Argentina, ILI activity continued its decreasing trend since its peak in June and July of this year [2013]. In Chile, the proportion of SARI-associated hospitalizations continued to decrease. In Paraguay, the ILI consultation rate was higher than expected for the time of year but with decreased influenza and respiratory virus detection. In Uruguay, the proportion of SARI-associated hospitalizations increased from levels reported in the previous week, but proportions of ICU admissions continued to decline.
Temperate countries of Southern Africa
After a peak in influenza activity in South Africa due to influenza A(H1N1)pmd09 in June 2013, a small 2nd peak was observed in the last few weeks due to increased influenza A(H3N2) and influenza B circulation.
Overall, in Australia, New Zealand, and the Pacific Islands, influenza activity seemed to have peaked.
In Australia, during the period from 30 Aug to 13 Sep 2013, the distribution of influenza types and subtypes was variable across jurisdictions. In Western Australia, influenza A(H3N2) remained the predominant virus subtype; however, the proportion of A(H1N1)pdm09 increased. Influenza type B continued to represent over half of Victoria's influenza notifications. In recent weeks, there have been increasing proportions of influenza B virus in Queensland and South Australia. Influenza positivity levels ranged from 15 percent (309/2114) in the national sentinel laboratory surveillance to 28.1 percent (56/199) in the Australian Sentinel Practices Research Network (ASPREN). The Influenza Complications Alert Network (FluCAN) sentinel hospital surveillance system reported that the rate of influenza associated hospitalisations had been relatively stable since mid-August 2013. Almost 15 percent of influenza associated hospitalisations were admitted directly to the ICU. The age distribution of hospital admissions showed peaks in the 0-9 and over 60 years age groups.
In New Zealand, ILI activity was almost at the baseline threshold in early September 2013 but decreased since then. Out of 303 samples received in the last week, 161 were positive for influenza (53 percent): 49 were influenza B, 16 were influenza A(H3N2), 22 were influenza A(H1N1)pdm09, and 74 were influenza A (not subtyped). In Auckland and Counties Manukau District Health Boards, decreased influenza activity was reported in community surveillance and hospital surveillance.

Influenza positivity levels ranged from 15 percent (309/2114) in the national sentinel laboratory surveillance to 28.1 percent (56/199) in the Australian Sentinel Practices Research Network (ASPREN). The Influenza Complications Alert Network (FluCAN) sentinel hospital surveillance system reported that the rate of influenza associated hospitalisations had been relatively stable since mid-August 2013. Almost 15 percent of influenza associated hospitalisations were admitted directly to the ICU. The age distribution of hospital admissions showed peaks in the 0-9 and over 60 years age groups.
In New Zealand, ILI activity was almost at the baseline threshold in early September 2013 but decreased since then. Out of 303 samples received in the last week, 161 were positive for influenza (53 percent): 49 were influenza B, 16 were influenza A(H3N2), 22 were influenza A(H1N1)pdm09, and 74 were influenza A (not subtyped). In Auckland and Counties Manukau District Health Boards, decreased influenza activity was reported in community surveillance and hospital surveillance.

#MERS #Coronavirus WHO Update October 14, 2013
14 October 2013 -
WHO has been informed of an additional two
laboratory-confirmed cases of Middle East respiratory syndrome
coronavirus (MERS-CoV) infection in Saudi Arabia.
The patients, both men, aged 55 and 78, were from Riyadh region. They became ill at the end of September 2013 and died in the beginning of October 2013. Both the patients were reported to have had no contact to a known laboratory-confirmed case with MERS-CoV.
Globally, from September 2012 to date, WHO has been informed of a total of 138 laboratory-confirmed cases of infection with MERS-CoV, including 60 deaths.
Based on the current situation and available information, WHO encourages all Member States to continue their surveillance for severe acute respiratory infections (SARI) and to carefully review any unusual patterns.
Health care providers are advised to maintain vigilance. Recent travellers returning from the Middle East who develop SARI should be tested for MERS-CoV as advised in the current surveillance recommendations.
Specimens from patients’ lower respiratory tracts should be obtained for diagnosis where possible. Clinicians are reminded that MERS-CoV infection should be considered even with atypical signs and symptoms, such as diarrhoea, in patients who are immunocompromised.
Health care facilities are reminded of the importance of systematic implementation of infection prevention and control (IPC). Health care facilities that provide care for patients suspected or confirmed with MERS-CoV infection should take appropriate measures to decrease the risk of transmission of the virus to other patients, health care workers and visitors.
All Member States are reminded to promptly assess and notify WHO of any new case of infection with MERS-CoV, along with information about potential exposures that may have resulted in infection and a description of the clinical course. Investigation into the source of exposure should promptly be initiated to identify the mode of exposure, so that further transmission of the virus can be prevented.
WHO does not advise special screening at points of entry with regard to this event nor does it currently recommend the application of any travel or trade restrictions.
WHO has convened an Emergency Committee under the International Health Regulations (IHR) to advise the Director-General on the status of the current situation. The Emergency Committee, which comprises international experts from all WHO Regions, unanimously advised that, with the information now available, and using a risk-assessment approach, the conditions for a Public Health Emergency of International Concern (PHEIC) have not at present been met.

Adaptive evolution of bat dipeptidyl peptidase 4 (dpp4): implications for the origin and emergence of Middle East respiratory syndrome coronavirus
Virology Journal 2013, 10:304 doi:10.1186/1743-422X-10-304

Abstract (provisional)
Background
The newly emerged Middle East respiratory syndrome coronavirus (MERS-CoV) that first
appeared in Saudi Arabia during the summer of 2012 has to date (20th September 2013)
caused 58 human deaths. MERS-CoV utilizes the dipeptidyl peptidase 4 (DPP4) host cell
receptor, and analysis of the long-term interaction between virus and receptor provides
key information on the evolutionary events that lead to the viral emergence.
Findings We show that bat DPP4 genes have been subject to significant adaptive evolution,
suggestive of a long-term arms-race between bats and MERS related CoVs. In particular,
we identify three positively selected residues in DPP4 that directly interact with
the viral surface glycoprotein.
Conclusions
Our study suggests that the evolutionary lineage leading to MERS-CoV may have circulated
in bats for a substantial time period.
