A veterinarian's experience of the spring 2004 avian influenza outbreak in Laos.

Since it was first reported in December 2003, the outbreak of avian influenza A/H5N1 has spread to at least nine countries in Asia, affected multiple species of animals, and caused at least 42 human deaths. The magnitude and extent of this zoonotic outbreak are unprecedented, continue to grow, and threaten the start of a global human influenza pandemic. Control of the H5N1 outbreak has required the implementation of integrated human and veterinary health surveillance and response efforts. These efforts have also necessitated an unprecedented level of bilateral and multilateral international communication and cooperation. This report describes the contribution of one public-health veterinarian to the H5N1 outbreak response effort in Laos, and emphasises the value of multidisciplinary approaches to addressing this and future emerging infectious disease outbreaks.
