The World Health Organization is urging countries to increase surveillance for bird flu after the first case was detected in a child in the United States. There has been a small but growing number of H5N1 avian influenza infections in humans worldwide. The virus first emerged in 1996, leading to outbreaks in birds and infections in mammals. The risk to the general public is low, but higher for those working directly with livestock animals. The importance of thorough investigations, testing, and proper protective equipment to prevent the spread of the virus is emphasized. The WHO is preparing for a potential flu pandemic and stresses the need for vigilance.
