The CDC issued a Health Alert Network (HAN) Health Advisory on May 8, 2026, to inform clinicians and health departments about a new multi-country cluster of hantavirus disease cases caused by the Andes virus. As of that date, eight cases (six confirmed and two suspected), including three deaths, were reported. The advisory emphasized the potential for imported cases into the United States, although the risk of broad spread is considered extremely unlikely. Investigations are ongoing to assess exposure risks for American passengers from the cruise ship that departed from Ushuaia, Argentina.
