The Middle East Respiratory Syndrome Coronavirus (MERS-CoV) has claimed one more life in the Sultanate.

According to the Ministry of Health, the Sultanate's second MERS coronavirus patient died of lung failure in a hospital last Monday.

"A 59-year-old MERS coronavirus patient, who was under treatment, died on December 30. He had lung failure and pneumonia," the Ministry of Health said, while adding that the ministry is prepared to deal with these situations.

The Sultanate's first MERS coronavirus patient died in the hospital on November 10. The first MERS-CoV victim, who was admitted to the hospital in Nizwa in October, was suffering from diabetes and high blood pressure, among other complaints.

Last week, the Saudi health authorities announced a new casualty of MERS-CoV, bringing to 57 the number of people killed by the coronavirus in the country with the most fatalities.

The MERS-CoV, which can cause coughing, fever and pneumonia, emerged in Saudi Arabia last year and its occurance has been reported in Qatar, France, Germany, Italy, Tunisia and Britain.

MERS-CoV is considered a deadlier but less-transmissible cousin of the SARS virus that erupted in Asia in 2003 and infected 8,273 people, nine per cent of whom died.

Taiwan reports 2nd case of imported #H7N9 in 2013 (update)

2013/12/31 22:06:54

Taipei, Dec. 31 (CNA) Health authorities confirmed Tuesday that a Chinese tourist in Taiwan has been infected with the H7N9 strain of bird flu, marking the second imported H7N9 infection this year.

The infected, an 86-year-old man from Jiangsu Province, is still in Taiwan receiving treatment, though most of his 25-person tour group has already returned to China, according to the Centers for Disease Control (CDC).

Two of his daughters have stayed with him but have thus far shown no symptoms associated with the virus. The man entered Taiwan Dec. 17 and began showing symptoms two days later, starting with a loss of appetite. On Dec. 23, he reported tightness of the chest before being rushed to an emergency room the next day, where he was put on a ventilator to treat pneumonia.

An infectious diseases experts familiar with the case said he was not surprised by the second case of H7N9 coming from China following the first back in April. Even so, this patient's symptoms were slightly different from previously reported infections, indicating that doctors still face some difficulty in diagnosing the virus, he added.

The man's infection could mean that H7N9 has become prevalent across all of southern China even though, puzzlingly, major duck and chicken farms in the region have been found disease-free."Beware of the virus if you see any ducks in the Jiangnan (south of the Yangtze River) area," he cautioned.

Genetic marker indicates severity of #H7N9 infection

Wang Z. Proc Natl Acad Sci. 2013;doi:10.1073/pnas.1321748111.

• December 31, 2013

A group of researchers have identified a genetic marker that can predict which patients infected with the new influenza A(H7N9) strain will experience more severe disease, according to data published in Proceedings of the National Academy of Sciences.

Influenza A(H7N9) has infected 134 people in nine provinces in China and caused 44 deaths, according to the paper, which was published online Dec. 23. According to WHO, there is no evidence of sustained human-to-human transmission.

“By using genetic markers in blood and lung samples, we have discovered that there are certain indicators that signal increased susceptibility to this influenza,” Katherine Kedzierska, PhD, associate professor in the department of microbiology and immunology at the University of Melbourne in Australia, said in a press release. “Higher than normal levels of cytokines, driven by a genetic variant of a protein called IFITM3, tells us that the severe disease is likely.”

Lower levels of plasma inflammatory cytokines at hospital admission were associated with faster recovery among 18 patients admitted to the hospital with H7N9, but high concentrations of interleukin-6, IL-8 and macrophage inflammatory protein-1 beta were associated with less favorable or fatal outcomes, the researchers wrote.

When they analyzed bronchoalveolar lavage samples, they found up to 1,000-fold greater cytokine and chemokine levels relative to plasma samples. They also found that patients with the rs12252-C/C genotype of IFITM3 had more rapid disease progression and were more likely to die than patients with the rs12252-T/T or rs12252-T/C genotypes.

“We call this a Cytokine Storm and people with the genetic variant of the protein IFITM3 are more likely to succumb to severe influenza infection,” Kedzierska said. “Being able to predict which patients will be more susceptible to the emerging influenza strain will allow clinicians to better manage an early intervention strategy.”

Disclosure: Kedzierska and colleagues report no relevant disclosures.

World Health Organization, H7N9 is currently limited to "the limitations of human transmission stage." Epidemic center, said commander Zhang Fengyi, H7N9 flu outbreak so far, only five cases of human to human transmission limitations cases.
Although imported from mainland tourists in this country went to Taipei, Taoyuan, Nantou Tou, eluanbi Pingtung, Hualien Taroko so many tourist attractions, is still in a hospital in the northern part of the treatment in the intensive care unit, but was its first test weakly positive, low viral load.
Due to the frequent cross-strait exchanges, enhance Taiwan's epidemic level is? Zhang Fengyi said that if the virus mutated to human transmission stage, quarantine and epidemic prevention policy will be updated.
Director of Children's Infectious Diseases Hospital, National Taiwan University, said Li-Min Huang, mainland epidemic widespread than imagined, he judged the entire south of the Yangtze River has a virus exists, calling the people must be vigilant.

Hong Kong Health Department: Case of #H9N2 Guangdong Province, Shenzhen

December 30, 2013

 Health Department today (December 30) afternoon received notification of the Hong Kong Centre for Health Protection, Hong Kong case of human infection with influenza A H9N2 appears influenza cases.

Under the notification, the case of 86-year-old man, living in Guangdong Province, Shenzhen Luohu; 28, chills, cough and sputum, Hong Kong via Lo Wu Control Point to the hospital for treatment, isolation ward is now receiving treatment in a stable condition. After testing samples from patients, diagnosed in 30 people infected with influenza A H9N2 influenza.

Influenza viruses are divided into A (A), B (B), propylene (C) three types, can cause a worldwide influenza pandemic, it is particularly important; B is generally only cause local epidemics, hepatitis C is generally only cause sporadic disease eg . With influenza A virus hemagglutinin surface (Hemagglutinin, abbreviated H) and neural aminotransferase enzyme (Neuraminidase, referred to as N) are two major antigens; hemagglutinin total of 1 to 16, a total of neuraminidase type 1 to 9 . Influenza virus and by different combinations of the same H N named as 2009 H1N1 pandemic and now H7N9, H10N8 and so on. Influenza is important that the H and N antigens change easily generate a new subtype; But human immunity to the new subtype is not high, so often caused by different levels of pandemic. When a new flu virus appears in the human, because humans have no resistance to stress, there may be a worldwide pandemic. Causes new type of influenza virus is the human influenza virus and nonhuman influenza viruses (such as avian influenza virus) gene recombination, or old subtype occur again, or animal influenza virus changed the host specificity and so on.

Health Bureau said that the weather becoming cooler, the influenza virus is likely to once again active. Health will continue to state health departments and health departments and neighboring regions, the World Health Organization to maintain close contact and closely monitoring the situation around, and through cross-sectoral and public-private cooperation in the health care system, to carry out the prevention and response.

For the prevention of influenza infection, health authorities urged the public to pay attention to the following matters:

 Avoid visiting, and have suffered outbreaks of human infection with avian influenza A regional markets, farms and other birds have a place to sell or display;

 Avoid contact with sick birds or other animals and their secretions, excretions; case of contact should wash their hands immediately;

 Do not eat undercooked poultry meat, offal, blood products and eggs;

 attention to personal hygiene, wash hands frequently;

 symptoms such as fever, cough, breathing difficulties, should wear a mask, a doctor as soon as possible, and to detail the history of travel and contact history animal doctor.
