Cruise ship outbreak alerts

Cruise ship outbreak alerts on OutbreakThreat link to WHO Disease Outbreak News, CDC Health Alert Network messages, and health department postings - not rumor boards. In 2026, agencies reported both gastrointestinal cruise clusters and a hantavirus investigation tied to ship travel; always read the pathogen named in the official notice.
