Frequently asked questions
Can hantavirus spread from person to person?
Generally no. In most cases, hantavirus does not spread from person to person.
The only documented exception is the Andes virus in South America, where rare person-to-person transmission has been reported. All other hantaviruses (Sin Nombre, Puumala, Hantaan, Seoul, etc.) are not contagious between people.
Can you get hantavirus from pets?
No. Dogs, cats, and other pets do not spread hantavirus to humans. However, pets may bring infected rodents into contact with humans.
Is there a vaccine for hantavirus?
No. There is currently no approved vaccine for hantavirus for human use anywhere in the world.
Research is ongoing, but no vaccine is commercially available yet.
Can hantavirus be cured?
There is no specific antiviral treatment or cure.
Early diagnosis and supportive care (oxygen, fluids, intensive care) are critical. The earlier a patient receives medical attention, the better the outcome.
How long is the incubation period?
Usually 1 to 8 weeks after exposure.
Most people develop symptoms within 2 to 4 weeks, but it can be as short as a few days or as long as several months.
Can you get hantavirus from food?
Very unlikely. Properly cooked food is safe.
The main risk is inhaling dust contaminated with rodent urine or droppings. Contaminated food that is not cooked could theoretically pose a risk, but this is not a common transmission route.
Is it safe to travel to endemic areas?
Yes, with precautions.
Most travelers are at very low risk. Simple precautions include:
- Avoiding contact with rodents and their nests
- Not camping near rodent burrows
- Using sealed food containers
- Wearing a mask when cleaning dusty cabins or sheds
Can domestic pet rats carry hantavirus?
Generally no. Pet rats bred in captivity and kept in clean environments are not a significant source of hantavirus. Wild rodents are the main reservoir.
