Hantavirus questions, answered

What is Hantavirus?
Hantaviruses are a family of RNA viruses carried mainly by rodents that can cause severe human disease. New World hantaviruses (Americas) cause Hantavirus pulmonary syndrome (HPS) — a respiratory illness with a case fatality rate of approximately 38% in the United States (Sin Nombre virus) and up to 50% in South America (Andes virus), per CDC and WHO. Old World hantaviruses (Europe, Asia) cause haemorrhagic fever with renal syndrome (HFRS); CFR varies by strain — Puumala and Seoul virus typically under 1%, Hantaan and Dobrava (genotype Dobrava) 5–15%, Dobrava-Kurkino under 1%.
How is Hantavirus transmitted?
People are typically infected after inhaling aerosols from the urine, droppings, or saliva of infected rodents — most commonly when cleaning enclosed rural spaces such as cabins or storage sheds. Rodent bites and contaminated food can also transmit the virus. Person-to-person transmission is rare and has only been documented for Andes virus in southern South America. The May 2026 MV Hondius cruise-ship cluster was attributed by WHO to limited human-to-human transmission of Andes virus in the closed shipboard environment.
What are the symptoms of Hantavirus infection?
Early symptoms (1–8 weeks after exposure) resemble flu: fever, fatigue, muscle aches, headache, and gastrointestinal symptoms. Late-stage HPS progresses to rapid respiratory failure due to fluid in the lungs. HFRS additionally causes acute kidney injury and bleeding. Seek urgent medical care if these symptoms follow possible rodent exposure.
Is there a vaccine or specific treatment for Hantavirus?
Two inactivated HFRS vaccines are licensed in Asia: Hantavax (Korea Green Cross, approved in South Korea since 1990, targeting Hantaan virus) and a bivalent inactivated Hantaan/Seoul vaccine routinely used in China. Neither protects against the HPS-causing strains found in the Americas, and neither is approved in Europe or North America. There is no specific antiviral therapy; care is supportive — oxygen, fluid management, and intensive care for severe cases. Prevention focuses on rodent control and avoiding aerosolised rodent waste.
How is the case fatality rate calculated on Hantatracker?
Case fatality rate (CFR) is computed as confirmed deaths divided by confirmed cases × 100, aggregated across all reported sources. The site only displays CFR for clusters of at least 30 confirmed cases — below that threshold, the ratio is statistically unstable and misleading. Reporting completeness also varies by country and over time, so the value shown is an indicator, not a clinical estimate.
Where does Hantatracker source its data?
Case data is aggregated from the World Health Organization (WHO) Disease Outbreak News feed, the U.S. Centers for Disease Control and Prevention (CDC) hantavirus surveillance pages, national health authorities including ECDC, PAHO and KDCA, and curated international news via NewsAPI and GDELT. AI-assisted normalisation extracts country, region, and a one-sentence summary; all entries link back to the original report.

About Hantatracker

Hantatracker is an open dashboard for tracking Hantavirus activity in real time. We aggregate data from World Health Organization (WHO), Centers for Disease Control and Prevention (CDC), NewsAPI and use AI-assisted normalisation to surface outbreaks faster than manual reporting alone.
