New flu virus in India likely from Australia
MUMBAI: A virus that is new to the Indian shores could just be contributing to the current flu epidemic sweeping across the state, especially Pune, say doctors.
While the swine flu-causing H1N1 virus is also an import from Mexico, the new virus that has got National Institute of Virology doctors scrambling for data, is considered to be Australian in origin.
Called the Australian Ross River virus, it is similar to the dengue and chikungunya-causing viruses. Like chikungunya (CHIK-V), it, too, causes arthritis-like pain in the joints.
However, the talk of the Australian virus has incensed state health officials, some of whom feel it could be a covert operation to sell expensive diagnostic kits. "This year, we are seeing a lot of variation in viruses and their manifestations, be it dengue or chikunguya. What is being touted as the Ross River virus could just be a new variant of CHIK-V," said a senior doctor from the health department.
On Saturday, health minister Suresh Shetty told TOI that four samples from patients admitted to Sassoon Hospital in Pune had been sent to NIV to test for the Ross River virus.
"We have got one sample's result as CHIK-V, and are awaiting results for the other samples," he said, adding that NIV director Dr A C Misra was confident that the other samples too would be negative for the Australian virus.
However, a senior health officer who wanted to be anonymous said that NIV had isolated the virus in eight samples.
Taiwan: CDC begins national bird flu vaccination program
2010/09/01 Chen Li-ting and Fanny Liu)
Taipei, Sept. 1 (CNA) The Centers for Disease Control (CDC) began a nationwide program to provide free vaccinations against influenza A virus subtype H5N1, also known as bird flu, that is scheduled to last until Sept. 30, the centers said Wednesday.
"With new infections in poultry being reported in several countries including China, Vietnam and Indonesia, risks still exist for the disease to spread in the country, " CDC Deputy Director-General Chou Jih-haw said.
The centers urged medical personnel in charge of disease control and prevention, animal quarantine officers, security check officers at airports and ports, coast guard officers, and people who frequently visit bird-flu affected countries to participate, Chou said.
Chou said a total of 190,000 doses of the vaccine that will expire at the end of November are available to the public during the one-month inoculation program.
Although the bird flu vaccination will be free of charge, citizens still need to pay registration fees and medical examination fees to receive the inoculation at designated hospitals, clinics or public health centers, he added.
Meanwhile, Chou also announced that seasonal flu vaccinations will kick off Oct. 1, with 2.98 million doses of government-funded vaccine available for high-risk groups.

Environmental Persistence of a Highly Pathogenic Avian Influenza (H5N1) Virus
Environ. Sci. Technol., Article ASAP
DOI: 10.1021/es1016153
Publication Date (Web): September 3, 2010
Copyright © 2010 American Chemical Society
Abstract:
Human cases of disease caused by highly pathogenic avian influenza (HPAI) viruses of the H5N1 subtype are rare, yet characterized with a mortality rate of approximately 60%.
Tests were conducted to determine the environmental persistence of an HPAI (H5N1) virus on four materials (glass, wood, galvanized metal, and topsoil) that could act as fomites or harbor the virus.
Test coupons were inoculated with the virus and exposed to one of five environmental conditions that included changes in temperature, relative humidity, and simulated sunlight.
At time periods up to 13 days, the virus was extracted from each coupon, and quantified via cytopathic effects on Madin−Darby canine kidney cells.
The virus was most persistent under the low temperature condition, with less than 1 log reduction on glass and steel after 13 days at low relative humidity.
Thus, at these conditions, the virus would be expected to persist appreciably beyond 13 days.

Mutated Avian Flu Can Infect Humans
Previously reported on here
[Out of Japan]
2010/09/02
BY YURI OIWA THE ASAHI SHIMBUN
A strain of highly pathogenic avian influenza (H5N1) that mutated in pigs in Indonesia has acquired the ability to infect humans, researchers have found.
The discovery was made by a team led by virologist Yoshihiro Kawaoka of the University of Tokyo's Institute of Medical Science.
"There are concerns that a highly pathogenic flu virus which can easily be transmitted to humans could spread without being noticed," Kawaoka said. "Pigs must be tested for viruses even if they don't show symptoms."
Kawaoka and other Japanese researchers, in cooperation with Indonesia's Airlangga University, examined nasal, fecal and serum samples from 702 randomly chosen pigs in 14 provinces from 2005 to 2009.
Of pigs examined from 2005 to 2007, 7.4 percent yielded avian flu strains, which further studies showed were from an outbreak among poultry in the neighborhood.
Among 39 virus samples analyzed, one was found to have the ability to attach itself to human nasal or throat cells.
In the 2008-2009 survey, pigs showed traces of past infections, but no viruses were isolated.
Avian influenza usually does not infect humans. But because pigs are susceptible to both avian and human flu, the flu strain in question is believed to have mutated in an infected pig.
"Our data suggests that pigs are at risk of infection during outbreaks of influenza virus A (H5N1) and can serve as intermediate hosts in which this avian virus can adapt to mammals," the team said in a report published in the online edition of the journal "Emerging Infectious Diseases" of the U.S. Centers for Disease Control and Prevention.

Avian flu still likely to strike in humans, says Welsh expert
Aug 31 2010 by David Williamson, Western Mail
THE threat of bird flu crossing over to humans and igniting a pandemic remains real, one of Wales’ leading experts on health and disaster management has claimed.
Alan Hawley, who until recently was the UK’s Director General of Army Medical Services, said climate change and international food scarcity has the potential to spread social and economic chaos across the globe.
His comments follow the decision of the Assembly Government to reduce the surveillance of live wild birds for avian influenza. Instead, attention will be focused on dead birds.
However, Prof Hawley said bird flu is not the greatest threat to Wales and the world.
The former major general, who is now the University of Glamorgan’s professor of disaster studies, described the Assembly Government’s decision to narrow the field of monitoring as “quite sensible”.
He said: “I think, scientifically, you have to constantly re-prioritise what you are doing. We have got a resource issue and hard decisions have to be made; I’m really glad I’m not a politician.”
But he said the threat of avian flu mutating into a form which could be passed between people “absolutely” remained on the radar.
He said: “The one we worry about is the avian epidemic where it moves from birds to the human species. I think that’s likely to happen, just being dispassionate about it.
“It will be bad enough to give us a jolt, but the technology and the modern public health techniques will allow us to cope with it.”
Describing his greatest fears, he said: “What really worries me is the climate change issue and the associated population-food mismatch. If you put these together I just don’t see a future of increasing political instability.
“That’s not good for any of us.”
Prof Hawley said it is a mistake to expect a future flu pandemic to claim 50 million lives, as took place with the 1918 Spanish flu outbreak.
He said: “If you think about it, it’s a different world. It was the pre-antibiotic era, pre-mass medication. The peoples that were affected had just gone through a major war and all that meant for infrastructure and nutrition.”
Confident that today’s health system could respond to the challenge, the professor – who served in Bosnia, Rwanda, Kosovo, Sierra Leone, Afghanistan and Iraq – said: “You don’t want to be the one of the first victims of a pandemic but if you get over the first six months, normally we have a coping method.”
Explaining the rationale for changing the way birds are monitored, an Assembly Government spokesman said: “Surveillance for avian influenza in wild birds has not stopped.
“The decision was taken in line with expert opinion across Europe that the continued testing of live wild birds is of limited value in detecting the H5N1 subtype of avian influenza.
“The changes made in respect of wild birds for avian influenza will give the taxpayer the best value for money whilst we continue to monitor the disease.”
He added: “It is important to make the distinction between avian influenza in birds, and pandemic flu in humans. Avian influenza is a disease of birds not humans.
“It is possible for people to become infected but they rarely are. There are many strains of avian influenza, which vary in their ability to cause disease in humans and there is no evidence that H5N1 has acquired the ability to pass easily from person to person.”
In November 2008, the UK became officially free from avian influenza according to the World Health Organisation.
The spokesman added: “With regards to outbreaks of avian influenza in birds in other countries, infections among domestic poultry have become endemic in certain areas in the world and the UK Department for Environment, Food and Rural Affairs monitors the international disease situation closely.”
Describing the measures in place to protect people from future flu outbreaks, he said: “With regards to pandemic flu in humans, the WHO continually assesses the public health threat and remains in contact with the Assembly Government, the Department of Health and the other devolved administrations.”
Southeast Asian health ministers’ meet in Thailand
August 30th, 2010
New Delhi, Aug 30 (IANS) Health ministers from 11 Southeast Asian countries and World Health Organization (WHO) experts will meet in Thailand Sep 7-10 to discuss key health issues in the region, an official statement said Monday.
The annual meeting of the health ministers is a forum to exchange national experiences on the social, political, and economic dimensions of health.
The health ministers’ meeting are expected to discuss the prevention and containment of antimicrobial resistance, injury prevention and safety promotion, acute diarrhoea and respiratory infections’, healthy ageing, addressing inequality in maternal and neonatal health, universal health coverage and world health.
This year’s meeting will take place in the wake of newer, fatal attacks in the form of Superbug and Severe Acute Respiratory Syndrome (SARS), Influenza (H1N1 and H5N1) viruses and an increasing number of deaths due to respiratory infections.
Sixty-one cluster outbreaks of influenza reported since July: CDC
2010/09/04 21:31:44 | ||
CDC Deputy Director General Chou Jih-haw said the AH3 type was followed by eight clusters of AH1 type, four clusters of B type, four clusters of the combination of two types, and one cluster whose virus type is yet to be identified. "The clusters of influenza AH3 virus have increased since August," Chou also said. The clusters of outbreaks mainly took place in nursing homes for the elderly, prisons and hospitals. Meanwhile, Taipei City's Department of Health confirmed Saturday a cluster outbreak of influenza A in a temple in suburban Taipei. Health officials said that several monks began to show symptoms of influenza on Sept. 2, and the patients in three cases suffered more serious conditions and were sent to the hospital. The CDC also said that although the outbreak of H1N1 is not as serious as last year, it still can threaten young people. The CDC urged the public to get inoculated as vaccination is still the safest and most effective way to avoid being infected and developing serious illness. People can check on the website http://tcgwww.taipei.gov.tw or call 2375-3782 for information about 29 medical institutions in Taipei that offer free H1N1 vaccinations, the CDC said. |

Satellite Data Reveals Why Migrating Birds Have a Small Window to Spread Bird Flu
ScienceDaily (Sep. 3, 2010)
Excerpt:
Excerpt:
Dr Gaidet's team analysed 228 birds from 19 species using satellite telemetry from 2006 to 2009 over the bird flu affected areas of Asia, Europe and Africa. The results indicated that migrating wildfowl do have the potential to disperse H5N1 over extensive distances as mass migration can result in infected birds covering as much as 2900km before symptoms become apparent.
However, while this is theoretically possible the team found that direct virus dispersal by migrating birds would require asymptomatic infection to coincide precisely with the migration season. The results revealed a very small 'window' of between 5 to 15 days when dispersal of the virus over 500 km could occur.
It is crucial to the spread of disease over such a distance that an infected bird must not be showing the symptoms of infection. If the symptoms are evident then it is highly likely that the individual may not migrate, or at least they will be unable to cover the distance as well as a healthy bird.

Thailand: Experts warn deadly bird flu could return
Published: 2/09/2010 at 12:00 AM
Bird flu experts are warning the deadly H5N1 bird flu strain could re-emerge in Thailand even though there has been little sign of it for years.
Migratory birds and pet dogs and cats could possibly transmit avian influenza from animal to human without stringent disease surveillance, Pilaipan Puthavathana, a virologist at Siriraj Hospital's department of microbiology, said yesterday.
"Nobody dares to say the virus has been wiped out here as long as our neighbouring countries continue to report bird flu cases," she said in a summary of a three-year follow up on avian flu surveillance from animals to humans in Thailand.

Studies had found H5N1 antigens in cats and dogs. These animals could survive bird flu but transmit the virus to their owners.

The risk of H5N1 virus outbreaks re-appear
[H5N1 in pigs in Indonesia previously reported on here ]
Saturday, 04/09/2010, 03:25 (GMT 7)
Experts in Thailand has given warning of H5N1 avian influenza virus may re-appear and the outbreak in that country. Experts said that with the appearance again, this strain can be more powerful, can be transmitted from dogs and cats, birds to humans.
Bangkok Post newspaper said that from September 7-2006 far, it does not have any cases of H5N1 in humans in some countries while still neighbors. This suggests that Thailand still can recur H5N1, especially gulls often migrate from Qinghai and Xinjiang (China) to Thailand. Local authorities in China are still cases of influenza A/H5N1.
In Japan, scientists have discovered a type of H5N1 bird flu virus has changed in pigs in Indonesia and have the ability to spread from pigs to humans easily. The research team at the Institute of Medicine of the University of Tokyo fears the virus can spread from pigs to humans can be infected on a large scale without being detected.
According to scientists, avian influenza does not normally infect people. However, because pigs susceptible to both avian and human flu so it is believed that this newly discovered virus was altered in an infected pig.

Study blames gulls, not storks, for bringing in bird flu
A study has found that the bird that carried the influenza virus H5N1 into Thailand was a gull, not the openbill stork."We have scientific evidence that a seagull was the carrier of the birdflu virus, not the openbill stork," said Professor Pilaipan Puthavathana of Mahidol University's Department of Microbiology.
Pilaipan led a team of researchers who conducted a study to track migratory routes in Asian countries by using satellite telemetry. The Thai research on humananimal interface of avian influenza was supported by the US Centres for Disease Control and Prevention. It followed the migratory route of birds suspected of spreading the H5N1 virus into Thailand since 2007.
Researchers tracked the migratory route of the brownheaded gull, one of the winter visitors seen along the muddy beach at Bang Pu, Samut Prakan, every year from November to March. They started tracking the first gulls in March 2008 and a second group of seven gulls during February and March 2009. Gulls migrated out of Thailand to China in April and May. In October and November, the gulls moved south to India, Burma, and then Thailand.
Birds may stay over the winter in Thailand but some may fly further to Cambodia. Their migration can be divided into two main phases. In Phase 1, they spent November to April along the coast of the inner Gulf of Thailand; during the second phase from May to October, they wander around their breeding grounds in Qinghai, Tibet and Xinjiang in China.
The team isolated the H5N1 virus in four of 153 birds of this flock in 2005 and 2008. The flock might have played a role in the spread of H5N1 virus along its route.
The study showed that the migratory route of brownheaded gulls covered several countries that had been affected by highly pathogenic H5N1 viruses. Therefore, gulls were at risk of getting infected and spreading the influenza virus along their migratory routes. Nevertheless, it was necessary to explore whether the infected gulls were capable of migrating over long distances.
"This is the first study using satellite telemetry techniques to reveal the complete migratory routes of the brownheaded gull," Pilaipan said.
Researchers also found that the openbill stork did not migrate outside Thailand.
Previously, scientists believed the openbill stork might have migrated from other countries and spread the H5N1 virus in Thailand last year, but the recent study showed that indigenous storks had never migrated outside the country.
Pilaipan said the study would be handed to the Disease Control Department and the Department of National Parks, Wildlife and Plant Conservation so that they will collect random specimens of gulls, especially those that inhabit areas near tourist attractions, to monitor the spread of the H5N1 virus among birds and prevent its transmission to humans.
