Answers based on CDC, WHO, and peer-reviewed hantavirus research. For medical advice, always consult a qualified healthcare professional.
Myths vs. Facts
“Hantavirus spreads like COVID — person-to-person through the air”
MOSTLY FALSE — Most strains are NOT transmitted person-to-person. Only Andes virus (South America) has documented rare human-to-human transmission among close household contacts.
“Cats and dogs can carry and transmit hantavirus”
FALSE — Cats and dogs are not known hantavirus reservoirs. However, cats that hunt rodents can bring infected rodents into contact with you.
“There is a vaccine for hantavirus”
FALSE in most countries — No approved vaccine exists in the USA, Europe, or most of South America. A limited vaccine exists in South Korea for HFRS. Prevention is the only reliable protection.
“Hantavirus is the same as Ebola or Marburg”
FALSE — Hantavirus requires direct contact with infected rodent materials. It is not transmitted through person-to-person contact or bodily fluid exposure in the way hemorrhagic fevers like Ebola are.
“Only people in rural areas need to worry”
FALSE — Urban Seoul virus (carried by common house rats) infects people worldwide, including pet rat owners and city residents. Hantavirus risk is not exclusively rural.
“If you've been near a rodent, you'll get hantavirus”
FALSE — Most rodent exposure does not result in infection. Risk requires exposure to infected excreta specifically, usually through inhalation. Common sense precautions effectively reduce risk.
