A(H5N1)
Influenza A virus subtype H5N1 (A/H5N1) is a subtype of the influenza A virus which can cause illness in humans and many other animal species. A bird-adapted strain of H5N1, called HPAI A(H5N1) for highly pathogenic avian influenza virus of type A of subtype H5N1, is the highly pathogenic causative agent of H5N1 flu, commonly known as avian influenza ("bird flu"). It is enzootic (maintained in the population) in many bird populations, especially in Southeast Asia. One strain of HPAI A(H5N1) is spreading globally after first appearing in Asia. It is epizootic (an epidemic in nonhumans) and panzootic (affecting animals of many species, especially over a wide area), killing tens of millions of birds and spurring the culling of hundreds of millions of others to stem its spread. Many references to "bird flu" and H5N1 in the popular media refer to this strain. This was reprinted in 2005: According to the World Health Organization (WHO) and the United Nations Food and Agri ...

A/Fujian (H5N1)
: ''See Influenza for details about the illnesses and Influenza A virus subtype H5N1 and Influenza A virus subtype H3N2 for details about the causative agents.'' Fujian flu refers to flu caused by either a Fujian human flu strain of the H3N2 subtype of the ''Influenza A virus'' or a Fujian bird flu strain of the H5N1 subtype of the ''Influenza A virus''. These strains are named after Fujian, a coastal province in Southeast China. A/Fujian (H3N2) human flu (from A/Fujian/411/2002(H3N2) -like flu virus strains) caused an unusually severe 2003–2004 flu season. This was due to a reassortment event that caused a minor clade to provide a haemagglutinin gene that later became part of the dominant strain in the 2002–2003 flu season. A/Fujian (H3N2) was made part of the trivalent influenza vaccine for the 2004-2005 flu season and its descendants are still the most common human H3N2 strain. A/Fujian (H5N1) bird flu is notable for its resistance to standard medical countermeasures a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
