  2026 Hantavirus Outbreak: Testing for Potential Infection | HAN - CDC↗

  cdc.gov · 2026-06-01

  The CDC issued a Health Alert Network (HAN) Health Update on May 18, 2026, to inform clinicians and health departments about testing for suspected hantavirus infection, including Andes virus. This follows an outbreak of Andes virus reported to WHO on May 2, 2026, on a cruise ship in the Atlantic Ocean, which has raised concerns about potential imported cases to the United States. Andes virus is unique among hantaviruses for its person-to-person transmission, though the overall risk to the American public is considered extremely low.

  The CDC provides an overview of hantavirus disease in the United States, reporting 890 cases since surveillance began in 1993, as of the end of 2023. Hantavirus Pulmonary Syndrome (HPS) became a nationally notifiable disease in 1995. The initial surveillance efforts in 1993 were prompted by an outbreak of severe respiratory illness in the Four Corners region, encompassing Arizona, Colorado, New Mexico, and Utah. The CDC notes that county-level data is not publicly provided to protect patient identities.

  HEALTH INFORMATION - International SOS↗

  International SOS assesses the risk of hantavirus to travelers as low, as transmission is primarily from infected rodents, not person-to-person, except for the Andes virus. Hantavirus Pulmonary Syndrome (HPS) is caused by "New World" hantaviruses found in Canada, the United States, and South American countries including Argentina, Bolivia, Brazil, Chile, Panama, Paraguay, and Uruguay. The WHO and ECDC also assess the global risk from the current outbreak as low to very low.
