(CIDRAP News) An international team of experts has concluded that the H5N1 avian influenza virus in Vietnam has not recently improved its ability to spread to or among humans, according to news reports published today.
The finding suggests that the immediate risk of a flu pandemic is lower than previously believed, according to an Agence France-Presse (AFP) report.
(CIDRAP News) The recent outbreak of H5N1 avian influenza among wild waterfowl in western China could provide a launching pad to spread the disease throughout Asia and beyond, according to two reports published by leading science journals today.
(CIDRAP News) Indonesian investigators found the H5N1 avian influenza virus in chicken droppings near the home of three people who died of the virus this month, according to a report published yesterday.
Editor's note: This story was revised July 31 to clarify information about previous reports of H5N1 influenza viruses in Russia.
(CIDRAP News) News services said today the avian influenza outbreak reported last week in Russia involves the dangerous H5N1 strain, while two more fatal human cases of the illness were reported in Vietnam.
(CIDRAP News) The 7-year-old son of a Thai farmer who died 2 days ago of H5N1 avian influenza also has the virus, but there is no evidence that the boy caught it from his father, according to news services.
Reuters and Agence France-Presse (AFP) reports said the boy tested positive for the virus, but they didn't say what test was used or where it was done. The boy is hospitalized but is expected to recover.
(CIDRAP News) The World Health Organization (WHO) today confirmed that a 15-year-old Indonesian boy who died May 30 had H5N1 avian influenza, but the agency said four nurses who had suspicious symptoms after caring for avian flu patients were not infected.
(CIDRAP News) In a development that could complicate avian influenza control efforts, an Indonesian official said this week that some apparently healthy chickens showed evidence of H5N1 virus infection, according to the Jakarta Post.
(CIDRAP News) World health experts have been working under a general assumption that a feared reassortment between human and avian influenza virusesa scenario that could spark a pandemicmight only occur during a short winter interval, but researchers who recently examined virus circulation patterns warn that time frames for coinfection are wider and sometimes unpredictable.
(CIDRAP News) European health officials today reported signs of an increasing rate of resistance to oseltamivir (Tamiflu) in Europe's predominant subtype of influenza virus, but they cautioned that the rate seen in isolates tested so far may not reflect the real situation.
