Influenza A Virus Subtype H10N7
Influenza A virus subtype H10N7 (A/H10N7) is a subtype of the species Influenzavirus A, Influenza A virus (sometimes called Avian influenza, bird flu virus). H10N7 was first reported in humans in Egypt in 2004. It caused illness in two one-year-old infants, and residents of Ismailia, Egypt; one child's father, and a poultry merchant. The first reported H10N7 outbreak in the US occurred in Minnesota on two turkey farms in 1979 and on a third in 1980. "The clinical signs ranged from severe, with a mortality rate as high as 31%, to subclinical. Antigenically indistinguishable viruses were isolated from healthy mallards on a pond adjacent to the turkey farms". The Influenza A (H10N7) virus was also held responsible for an increased mortality of harbour seals () in Europe in 2014. First cases were reported in spring 2014 in Sweden and subsequently spread to Denmark. Within a few months the virus spread to the Wadden Sea area of Germany and the Netherlands causing the death of about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Influenzavirus A
'' A virus'' (''IAV'') causes influenza in birds and some mammals, and is the only species of the genus ''Alphainfluenzavirus'' of the virus family '' Orthomyxoviridae''. Strains of all subtypes of influenza A virus have been isolated from wild birds, although disease is uncommon. Some isolates of influenza A virus cause severe disease both in domestic poultry and, rarely, in humans. Occasionally, viruses are transmitted from wild aquatic birds to domestic poultry, and this may cause an outbreak or give rise to human influenza pandemics. Influenza A viruses are negative-sense, single-stranded, segmented RNA viruses. The several subtypes are labeled according to an H number (for the type of hemagglutinin) and an N number (for the type of neuraminidase). There are 18 different known H antigens (H1 to H18) and 11 different known N antigens (N1 to N11). H17N10 was isolated from fruit bats in 2012. H18N11 was discovered in a Peruvian bat in 2013. Each virus subtype has mutated i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
