Global Disease Outbreak Watch — Week of May 19, 2026
This week: a hantavirus cluster aboard a cruise ship spans six countries; Nipah virus resurfaces in India's West Bengal; H5N1 avian influenza continues its global spread with a fatality in Bangladesh; measles hits 30-year highs in the US; and the global disease burden of cholera and chikungunya in 2025 put into context.
This week's episode covers five active outbreak developments: a multi-country hantavirus cluster linked to cruise ship travel, Nipah virus in India's West Bengal state, continued H5N1 avian influenza human cases, a measles resurgence hitting 30-year highs in the United States, and 2025's global disease burden in cholera and chikungunya.
What's Covered
- Hantavirus — Multi-country, cruise ship linked (WHO DON issued May 4, 2026; ECDC technical brief May 6, 2026): 7 cases (2 confirmed, 5 suspected), 3 deaths as of May 4th. Vessel departed Argentina; itinerary included Antarctica, South Georgia, and South Atlantic islands. Possible Andes virus involvement raises human-to-human transmission concern.
