🇺🇸 HHS PREP Act declaration on Andes virus — published in the Federal Register under number 2026-10539 (public inspection on 24 May 2026) and announced the same day by HHS Secretary RFK Jr. on his official account @SecKennedy. In his statement, the Health Secretary said he had signed a targeted declaration under the PREP Act to support the development and deployment of medical countermeasures related to the Andes virus, with the goal of « removing obstacles to research and response efforts, while continuing to monitor the recent outbreak linked to the South Atlantic cruise ship ». Established press (The Hill, ABC News, WSBTV) confirms the declaration is in force until 18 July 2026 and that it protects the investigational use of favipiravir (an RNA-virus antiviral originally developed against influenza) as a potential treatment for hantavirus pulmonary syndrome. The declaration does not cover a vaccine and does not prejudge favipiravir's efficacy against Andes — it only lifts liability barriers for experimental use, within the scope of the MV Hondius outbreak and its chain of transmission. 🇫🇷 France — the strict line owned and documented (Le Parisien, Nicolas Berrod & Véronique Hunsinger, 24 May). The daily describes the backstage shift from self-isolation to mandatory hospital confinement for the 26 French contact cases (4 cruise passengers + 22 flight contacts on two planes), all still hospitalised despite the absence of symptoms. An option to soften the protocol toward home confinement had been considered earlier in the week, but the 12th case announced by the WHO on Friday 22 May reinforced Health Minister Stéphanie Rist's strict line. The government relied on epidemic modelling presented to it. 📊 Tally unchanged: 12 cases (10 confirmed + 2 probable), 3 deaths, 7 affected countries.
