ROME (AP) – The United Nations warned Monday of a possible resurgence of the deadly bird flu virus, saying wild bird migrations had brought it back to previously virus-free countries and that a mutant strain was spreading in Asia.
A mutant strain of H5N1, which can apparently sidestep defenses of existing vaccines, is spreading in China and Vietnam, the U.N. Food and Agriculture Organization said in a statement Monday. It urged greater surveillance to ensure that any outbreaks are contained.
Last week, the World Health Organization reported that a 6-year-old Cambodian girl had died Aug. 14 from bird flu, the eighth person to die from H5N1 avian influenza this year in Cambodia.
