On Apr. 21, 2024, the APHIS National Veterinary Services Laboratories announced it had made available 239 genetic sequences from the U.S. H5N1 clade 2.3.4.4b influenza virus recently found in samples associated with the ongoing highly pathogenic avian influenza (HPAI) outbreak in poultry and wild birds, and the recent H5N1 event in dairy cattle.

APHIS routinely publishes influenza genetic sequence data on GISAID (the Global Initiative on Sharing Avian Influenza Data).
