Chile's Health Ministry Declares Nationwide Hantavirus Alert

Chile hantavirus sanitary alert lethality increase multi‑threat response

Chile’s Ministry of Health issued a first‑ever sanitary alert for hantavirus, covering 13 of the country’s 16 regions from Atacama to Magallanes. The decree, published in the Official Gazette, will remain in force until 31 July 2027 and is part of a “multi‑threat” response that also addresses mosquito‑borne diseases such as dengue, Zika and chikungunya, as well as avian influenza.

The alert was triggered by a sharp rise in the virus’s lethality, which reached 39% this year with 46 confirmed infections and 18 deaths, compared with a lethality of 18% in 2025 (44 cases, 8 deaths). It grants health authorities extraordinary powers to procure supplies directly, hire specialised staff and accelerate surveillance and control measures. Public‑health guidance advises residents to avoid contact with rodents, ventilate closed houses, clean surfaces with chlorine, keep waste sealed and seek medical care promptly if they develop fever, intense muscle pain or respiratory difficulty after exposure in rural or semi‑rural areas.
