There is no evidence that the deadly H7N9 bird flu has yet spread between humans in China but health authorities must be ready for the virus to mutate at any time, a top US virologist has warned.
Anthony Fauci, the head of the National Institute of Allergy and Infectious Diseases (NIAID), said officials in China had studied more than 1,000 close contacts of confirmed cases and not found any evidence of human-to-human transmission.
“That is powerful evidence because if you had a thousand contacts with someone with the flu you would be pretty sure some of them would have been infected,” Fauci said in an interview with AFP.
