Declan Butler: Avian flu update: lull in new H7N9 cases

from Nature
14 May 2013

Epidemic has spread to three more Chinese provinces, but no new cases reported since 7 May.

An update to Nature's exclusive map of the H7N9 avian influenza shows how the virus expanded its geographical range in mainland China in late April. Since then, however, the epidemic has gone into a lull, with just one person falling ill with H7N9 since the start of May. The drop might reflect that authorities's control measures, such as the closure of live bird markets, are working, but it is also possible that the epidemic will rear its head again later.
