The 1918 Spanish flu virus has claimed more than 50 million lives. However, the mechanism of its high pathogenicity remains elusive; and the origin of the virus is controversial. The matrix (M) segment regulates the replication of influenza A virus, thereby affecting its virulence and pathogenicity. This study found that the M segment of the Spanish flu virus is a recombinant chimera originating from avian influenza virus and human influenza virus. The unique mosaic M segment might confer the vi ...[more]
