Hantavirus Spreads Beyond Ships: France reports community transmission in 2+ regions by May 25

96%

probability · 72% confidence · 14 days

Hantavirus outbreak escalating across multiple regions: France reports 11+ confirmed cases with one critically ill patient; Argentina outbreak reaching critical stage ('races to find origin'); cruise ship lockdown with 1,000+ passengers held. Close contacts in France tested negative 'so far' — language suggests early stage of community spread trajectory. Base rate for outbreak_spread (30 days) is 15%, but current evidence shows 2+ regions already affected (France + Argentina). Prior forecast at 94% for community transmission in 2+ regions by May 25; current signals show this threshold may already be met or exceeded. Probability moved from 94% → 96% (+2 points). High confidence in resolution.
