China, Pakistan, and Vietnam are in Bird Flu Trouble.
China and Pakistan have announced bird flu outbreaks among poultry, a day after two women, one in China and one in Vietnam, died of the virus. In Pakistan, there was a fresh outbreak of H5N1 in chickens, the fourth case in a month. China needs to be on alert, especially because they have the largest poultry population in the world. The country has done its best to educate those who handle poultry and mass immunize birds.
