Myth Hantavirus is spread through insect bites.

Fact No. Hantavirus is spread via rodent excreta (urine, feces, saliva), not insects. Inhalation of aerosolized virus particles is the primary route.

Myth All rodents carry Hantavirus.

Fact Only specific species like Deer Mice, Cotton Rats, Rice Rats, and Bank Voles are primary reservoirs. Most urban rodents like house mice rarely carry it.

Myth Hantavirus can spread from person to person like COVID-19.

Fact No. Andes virus is the ONLY hantavirus strain confirmed to exhibit human-to-human transmission, and even then it requires close prolonged contact.

Myth There is a vaccine for Hantavirus.

Fact No approved vaccine exists for HPS-causing hantaviruses. China and South Korea have vaccines for HFRS-causing strains (Hantaan/Seoul), but none for the Americas.

Myth If I get Hantavirus, I will definitely die.

Fact HPS has a ~38% CFR and HFRS has a much lower ~1-5% CFR depending on the strain. Early medical intervention and ICU supportive care significantly improve survival odds.

Myth Hantavirus is a new disease that emerged in 2026.

Fact Hantavirus was first isolated in 1976 (Hantaan River, Korea). HPS was first identified in the 1993 Four Corners outbreak. The 2026 MV Hondius cluster is merely the latest episode.
