摘要

Water birds are considered the reservoir for avian in-. uenza viruses. We examined this assumption by sampling and real-time reverse transcription–PCR testing of 939 Asian land birds of 153 species. In. uenza A infection was found, particularly among migratory species. Surveillance programs for monitoring spread of these viruses need to be redesigned
