The United Nations has called on nations in Asia to be extra careful after they detected the resurgence of bird flu in the continent. The UN said due to wild bird migrations bird flu is starting to finds its way again on virus-free countries in the past. The UN Food and Agriculture Organization also revealed that they have discovered a mutant strain of H5N1, which can can sidestep defences of existing vaccines.
The UN said the new kind of flu virus is spreading in China and Vietnam at the moment. The UN authorities said Asian countries need to tighten it watch on its new strain of bird flu virus to ensure it cannot spread and become an outbreak. The UN made the sound of alarm after the World Health Organization (WHO) 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.
The WHO revealed around the world there have been 331 human deaths from 565 confirmed bird flu cases since 2003 when it was first detected. Moreover, WHO said the virus was eliminated from most of the 63 countries infected at its peak in 2006, but it remained endemic in six countries: Bangladesh, China, Egypt, India, Indonesia and Vietnam.
