We examined this assumption by sampling and real-time reverse transcription–PCR testing of 939 Asian land birds of 153 species. Infl uenza A infection was found, particularly among migratory species. Surveillance programs for monitoring spread of these viruses need to be redesigned.en-USArticle10.3201/eid1410.080169openAccess
