H7N9 has mutated and may spread from human to human: expert
Chinese researchers have discovered mutations in the new strain of avian influenza A, known as H7N9, and have found that the virus has the ability to spread from human to human, the latest issue of the Guangzhou-based Southern Metropolis Weekly reported.
Although the H7N9 and H5N1 viruses have not had the ability to widely spread from human to human, after undergoing genetic mutations and redistribution through mutations, they become better able to bind to human cells in the upper respiratory tract and can evolve into bird flu strains with the ability to transmit among humans, the team says.
