Some countries have confirmed laboratory-detected cases, while others are monitoring close contacts.[3][2]

Vaccines and treatment: There is no licensed vaccine or universally curative antiviral for hantavirus pulmonary syndrome (HPS) as of May 2026; management is mainly supportive care with oxygen therapy and careful fluid management. Ribavirin is not routinely used for HPS but has some context in certain strains; prevention emphasizes rodent control and safe cleaning.[2]
