Avian influenza virus: new features related to its pathogenicity and strategies for fighting against it

Since Taubenberger´s team recreated each of the genes of influenza virus that caused the terrible pandemic of 1918-19 using the technique called reverse genetics and checked the infectious capacity of the newborn virus, it seems that its high pathogenicity may be due to disregulation of the innate i...

Assays to prevent the mild, moderate or severe risks of an eventual future pandemic affecting humans caused by the H5N1 subtype are now being carried out by preparing new vaccines and neuraminidase (= sialidase) inhibitors such as oseltamivir and zanamivir, as well as other agents that block the function of several components of the virus.
