On May 9, 2026, the U.S Centers for Disease Control and Prevention (CDC) issued a Health Alert Network (HAN) Health Advisory for a Multi-country Hantavirus Cluster Linked to Cruise Ship about a new cluster of hantavirus disease cases caused by infection with Andes virus. Hantavirus disease can cause severe illness and can be fatal. The infection risk to the American public remains extremely low.
Please review the HAN for recommendations and resources for clinicians and public health practitioners, health departments, laboratories, and for the public.
We encourage you to share this message widely with your network(s).
