Short answer
Hantaviruses are a family of viruses carried mainly by rodents. Some types can cause serious illness in people.
What it means
Hantavirus is not one single disease. CDC and WHO describe several Hantaviruses that can cause different illnesses, including Hantavirus pulmonary syndrome in the Americas and hemorrhagic fever with renal syndrome in parts of Europe and Asia.
What to know
Most prevention guidance focuses on avoiding contact with wild rodents, rodent droppings, urine, saliva, and nesting material. Hantavirus is uncommon, but severe cases can progress quickly.
When to check official guidance
Check CDC, WHO, your state or local public health department, or a healthcare professional if you have questions about exposure, symptoms, or a specific location.
