Trusted Health Basics From Trusted Sources
WHO and CDC describe hantaviruses as rodent-borne viruses that can
cause severe illness, including lung, heart, kidney, and blood-vessel
complications depending on the virus and region.
How exposure happens
People are most often exposed when fresh urine, droppings, saliva,
or nesting material from infected rodents is disturbed and breathed
in. Bites and contaminated surfaces are less common routes.
What to watch for
Symptoms may begin weeks after exposure and can start like many
other illnesses, including fever, headache, muscle aches, fatigue,
stomach pain, nausea, or vomiting. Mention rodent exposure to a
healthcare provider.
How to lower risk
CDC and WHO emphasize rodent control: seal gaps, store food securely,
reduce clutter and attractants, and avoid dry sweeping or vacuuming
droppings. Disinfect and dampen contaminated areas before cleanup.
How care is handled
WHO and CDC note that there is no single specific cure for hantavirus
infection. Care is supportive and may include close monitoring,
oxygen or breathing support, fluid management, or kidney support
when clinically needed.
