  Updated April 26, 2024
  
  This report provides an update to the December 29, 2023, report to include seven new human cases (5 in Cambodia, 1 in the United States and 1 in Vietnam) and recent activity in wild birds, poultry and other animals, including the multi-state veterinary outbreak in U.S. dairy cattle, and updated information on monitoring for H5N1 virus infections in the United States. Even given these updates, CDC believes the overall risk to human health associated with the ongoing outbreaks of highly pathogenic avian influenza A(H5N1) viruses has not changed and remains low to the U.S. general public at this time.
