Can you share any information about bird (avian) flu activity and transmission to humans? 

Avian influenza is circulating heavily around the world. We haven’t seen transmission to humans on a large scale. There have been a few cases of highly pathogenic avian influenza (HPAI0 in the U.S. but it’s rare. HPAI refers to the mortality in birds, not the mortality in humans. But HPAI is considered a special pathogen because we don’t have effective medical counter measures.
