Experimental adaptation of an influenza H5 HA confers respiratory droplet transmission to a reassortant H5 HA/H1N1 virus in ferrets
1 May 2012
Abstract excerpt
Only four mutations in H5N1 HA are required to enable ferret-to-ferret transmission of a reassortant virus containing the H5 HA and the remaining seven gene segments from a human pandemic H1N1 influenza virus. Whether avian H5N1 viruses can gain the ability to transmit between humans was uncertain. The viral haemagglutinin protein (HA) mediates virus binding to host-specific cellular receptors, but previous...
