Hantavirus is a rare but severe rodent-borne viral infection that can lead to life-threatening respiratory or kidney diseases. There is currently no specific cure, antiviral drug, or vaccine. Treatment primarily involves early intensive supportive care in a hospital to manage symptoms and support vital organ function.
Key Facts About Hantavirus
- Transmission: Humans are typically infected by inhaling airborne particles from dried rodent urine, droppings, or saliva. Most strains do not spread between humans, with the exception of the Andes virus, which has shown limited person-to-person transmission in close-contact situations.
- Diseases Caused:
- Hantavirus Pulmonary Syndrome (HPS): Common in the Americas; causes the lungs to fill with fluid, leading to severe breathing difficulty.
- Hemorrhagic Fever with Renal Syndrome (HFRS): Common in Europe and Asia; primarily affects kidney function and can cause internal bleeding.
- Mortality Rate: Hantavirus is highly dangerous, with a fatality rate for HPS reaching nearly 40% to 50%.
Treatment & Management
Since no specific cure exists, medical intervention focuses on helping the body survive the critical phase of the illness.

Treatment Method |
Description |
|
Intensive Care (ICU) |
Critical for monitoring heart, lung, and kidney function. |
|
Respiratory Support |
Oxygen therapy or mechanical ventilation (intubation) to assist breathing. |
|
ECMO |
A machine that takes over heart and lung function to oxygenate blood. |
|
Fluid Management |
Careful administration of IV fluids to balance blood pressure without overloading lungs. |
|
Antivirals |
Drugs like Ribavirin are sometimes used off-label, but their effectiveness for HPS is unproven. |
Prevention Strategies
Prevention is considered the most effective defense against the virus.
- Rodent Control: Seal gaps and holes in homes to prevent mice and rats from entering.
- Safe Cleaning: Do not sweep or vacuum dry rodent droppings, as this sends virus particles into the air. Instead, spray areas with a disinfectant or bleach solution before cleaning with a wet cloth.
- Proper Storage: Keep food and pet food in tightly sealed metal or thick plastic containers.
