Hantavirus persist in semen: Long‑term presence doesn’t mean contagious

Hantavirus persist in semen: what the data reveal

Recent studies confirm that Hantavirus persist in semen for extended periods, with some cases reporting detection up to ↓ 5 years. Scientists caution, however, that lingering viral RNA does not automatically translate into infectious risk. Detection does not equal transmission, says Dr. Maria Alvarez of the University of Chile, quoted in a Reuters interview. The Andes strain, the only hantavirus known to spread between humans, remains under intense scrutiny.

“Finding viral fragments years later is a laboratory observation, not a public‑health alarm,” the researcher warned.

Current guidance from the World Health Organization advises standard precautions for recovered patients, but no specific isolation period for semen has been mandated. Ongoing research aims to differentiate between viable virus and inert genetic remnants, a distinction that will shape future recommendations.
