Current Hantavirus Outbreak Situation

Situation at a glance

Last checked: May 26, 2026, 15:00 UTC. Latest source update: Official pages checked May 26, 2026; ECDC reports data as of May 26. Headline counts use the latest reviewed ECDC public page; WHO DON601 remains retained for risk, chronology, and earlier classification context.

Short answer

The current headline count remains tied to the latest checked official public source page: ECDC's daily outbreak page reports data as of May 26, including 13 total reported cases, 11 confirmed, 2 probable, 0 suspected, 0 current inconclusive cases, and 3 deaths. CDC says no U.S. cases have been confirmed as a result of this outbreak.

Source reconciliation

ECDC is the headline source checked for this build because its daily outbreak page is updated during the active outbreak and currently reports data as of May 26, 2026. WHO DON601, dated May 13, remains retained for global risk, earlier classification, and death-context records. CDC's current situation page focuses on U.S. response and risk; it states that no cases of Andes virus have been confirmed in the United States as a result of this outbreak.

Reuters and People reported on May 15 that WHO briefing statements lowered the total from 11 to 10 after the U.S. inconclusive case tested negative. Later ECDC public pages reconciled the underlying inconclusive-case issue; the May 26 ECDC status snapshot omits a current inconclusive category, so this tracker records current inconclusive cases as zero and keeps secondary reports as historical freshness triggers rather than headline sources.

Risk framing

For the general public and travelers outside the ship or close-contact context, official sources assess broad risk as low, very low, or extremely low depending jurisdiction. WHO assesses global risk as low. ECDC says EU/EEA general-population risk remains very low. CDC says the overall risk to the American public and travelers remains extremely low.

People who were onboard the ship, exposed passengers, high-risk contacts, or people contacted by public-health officials should follow the instructions from clinicians and public-health authorities. This tracker does not assign individual exposure risk.

What changed since last update

The site updated the canonical public-state records to the current ECDC daily outbreak page: the headline count is 13 total cases, 11 confirmed, 2 probable, 0 suspected, 0 current inconclusive cases, and 3 deaths. Pending news and hospital reports are exposed as separate layers and are not counted as official totals.
