- Andes virus (ANDV) is the only hantavirus known to be transmitted person-to-person.
- ANDV is endemic to areas of South America.
- ANDV can cause hantavirus pulmonary syndrome, which has a case-fatality rate of approximately 40%.
- On May 4, 2026, CDC was notified of seven cases of severe acute respiratory illness, including three deaths, among 147 persons aboard a cruise ship in the Atlantic Ocean.
- The illnesses aboard the cruise ship were later confirmed to be caused by ANDV.
- Seven cases of severe acute respiratory illness, including three deaths, were reported among 147 persons aboard the cruise ship.

- The monitoring totaled 88 contacts across 27 jurisdictions.
- All 88 contacts completed 42 days of monitoring, with no secondary ANDV infections identified.
- Worldwide, local health authorities assessed and monitored approximately 653 potentially exposed persons from 33 countries.
