WHO: No sign of sustained spread of H7N9 between humans

GENEVA - The World Health Organization said on Friday that there was no sign of "sustained human-to-human transmission" of the H7N9 virus in China, but it was important to follow up on some 400 people who were in close contact with the 14 confirmed cases.
"We have 14 cases in a large geographical area, we have no sign of any epidemiological linkage between the confirmed cases and we have no sign of sustained human-to-human transmission," WHO spokesman Gregory Hartl told a news briefing in Geneva.
