Hantavirus Global Situational Briefing — May 12, 2026

French passenger who developed symptoms during Tenerife-to-Paris repatriation tests positive for hantavirus — the highest-priority open question from May 11, now confirmed. A Georgia couple are both confirmed positive and transferred to Emory University Hospital's biocontainment unit; combined with a Nebraska case, the confirmed US count reaches at least 3. A Spanish passenger at Gómez Ulla military hospital is preliminary PCR-positive. Working cluster total: approximately 11 confirmed + 2 probable. WHO DON-600 sets the operative 42-day quarantine framework. Radboud University Hospital in Nijmegen places 12 staff in six-week preventive quarantine — the first hospital-acquired exposure cohort of the outbreak. MV Hondius departed Tenerife on May 11 evening, ETA Rotterdam May 17. Multinational genomic analysis confirms a single zoonotic spillover followed by human-to-human transmission; the virus is not a new variant. Traws Pharma announces plans for a hantavirus antiviral clinical candidate.

Hantavirus Global Situational Briefing — May 11, 2026

KLM flight attendant from Haarlem tests negative for hantavirus, resolving the highest-stakes open question from the May 10 briefing. MV Hondius evacuation is operationally complete with 94 passengers and crew from 19 countries dispersed across 8 repatriation aircraft; 34 crew remain aboard for disinfection voyage to Rotterdam. A French passenger developed symptoms during repatriation — results pending as May 12's priority watch item. The Swiss-sequenced complete Andes genome (ANDV/Switzerland/Hu-3337/2026) is now public. The Southern Cone picture darkens: Chile's 2026 CFR reaches 33% — nearly double last year — while Brazil records its first 2026 death and Santa Catarina's first 2026 case. Argentina's ANLIS-Malbrán confirms 99.99% Andes virus match at Cerro Centinela. El Niño onset probability at 61–70% projects sustained transmission pressure across the Southern Cone through late 2026.

Hantavirus Global Situational Briefing — May 10, 2026

MV Hondius docks at Tenerife Sunday morning as CDC draws sharp expert criticism for its belated Level 3 EOC activation, while WHO leads the international response without US partnership. Argentina's 2025–26 HPS season hits 101 confirmed cases and 32 deaths — the worst since 2018 — with Buenos Aires province now leading national case burden. A KLM flight attendant and two suspected Spain cases are the first potential secondary transmissions outside the ship. Indonesia's Seoul virus cluster spans 9 provinces with 23 confirmed cases. New research identifies the hantavirus L protein N-terminal domain as an antiviral target; Moderna confirms a preclinical mRNA vaccine program with Korea University dating to 2023.
