Avian Influenza: Information for Health Professionals and Laboratorians

In light of the recent case of human infection with highly pathogenic avian influenza A (H5N1) in North America, CDC is currently updating several of the H5N1 and general avian influenza interim guidance documents. The updated documents will be posted to this page as they are finalized. In the meantime, please refer to the most recent interim H7N9 and H5N1 documents available below.

Please note that until the updated documents are posted, and in instances when only H7N9 guidance is currently available, it is appropriate to use the H7N9 guidance for issues related to all human infection with avian influenza viruses that cause severe illness in people.
