Hantaviridae is a family of negative-sense, single-stranded RNA viruses in the order Elliovirales.[1][2] Unlike other members of the Bunyavirales, hantaviruses are not spread by biting insects, and instead persistently infect rodent hosts without ill-effect.[3]

It is named for the Hantan River area in South Korea where an early outbreak was observed.[4]

Impact

Hantaviruses are estimated to impact approximately 200,000 people annually worldwide and are responsible for causing two acute febrile illnesses in humans: Hantavirus pulmonary syndrome and hemorrhagic fever with renal syndrome.[2][5][6]

There are currently no licensed treatments or vaccinations available for hantavirus, however, multiple drugs have been shown to improve survival rates, including lactoferrin, ribavirin, favipiravir and vandetanib.[2]

Human infection with hantaviruses typically arises from exposure to virus-contaminated aerosols or contact with infected rodents, the natural host of the virus.[3][5] The only known exception to this is the Andes virus, the only hantavirus where person-to-person transmission has been recorded.[5]

Taxonomy

The family contains the following subfamilies and genera (-virinae denotes subfamily and -virus denotes genus):[7]

  • Actantavirinae
    • Actinovirus
    • Percilovirus
  • Agantavirinae
    • Agnathovirus
  • Mammantavirinae
  • Repantavirinae
    • Reptillovirus

Hantavirus outbreaks

In the past century, there have been two major hantavirus outbreaks: the first was during the Korean War (1950–1953), where 3,000 US troops were affected. The second outbreak was documented in the Four Corners area of the United States in 1993.[2][5]

Hantaviridae were involved in the 2026 MV Hondius hantavirus outbreak.[8]
