According to a study from the United States, "The 1918 influenza pandemic was exceptionally severe, resulting in the death of up to 50 million people worldwide. Here, we show which virus genes contributed to the replication and virulence of the 1918 influenza virus." "Recombinant viruses, in which genes of the 1918 virus were replaced with genes from a contemporary human H1N1 influenza virus, A/Texas/36/91 (Tx/91), were generated. The exchange of most 1918 influenza virus genes with seasonal influenza H1N1 virus genes did not alter the virulence of the 1918 virus; however, substitution of the hemagglutinin (HA), neuraminidase (NA), or polymerase subunit PB1 genes...
