WHO’s response to hantavirus cases linked to a cruise ship
Dr Tedros Adhanom Ghebreyesus, WHO Director-General, briefed media today on a cluster of hantavirus cases linked to a cruise ship, the MV Hondius.Eight cases have been reported so far, including three deaths. Five of the 8 cases have been confirmed as hantavirus.The hantavirus in
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 case fatality rates of 30–40%. Old World hantaviruses (Europe, Asia) cause haemorrhagic fever with renal syndrome (HFRS), with case fatality rates of 1–15% depending on the strain.
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.
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?
No vaccine is currently approved for use outside of a limited number of countries (primarily for HFRS in parts of Asia). 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 Hentatracker?
Case fatality rate (CFR) is computed as confirmed deaths divided by confirmed cases × 100, aggregated across all reported sources. Because reporting completeness varies by country and over time, the CFR shown is an indicator and should not be interpreted as a clinical estimate.
Where does Hentatracker 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, and curated international news via NewsAPI. AI-assisted normalisation extracts country, region, and a one-sentence summary; all entries link back to the original report.
About Hentatracker
Hentatracker 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.
