What Is Hantavirus?
Hantavirus is a rare but potentially deadly virus commonly spread through exposure to infected rodents, their urine, saliva, or droppings.
Symptoms may include:
- Fever
- Muscle pain
- Headache
- Fatigue
- Vomiting
- Shortness of breath
- Severe pneumonia-like illness
In serious cases, the disease can rapidly progress into Hantavirus Pulmonary Syndrome (HPS), which can be fatal.
Why Experts Are Concerned
Most hantavirus strains do not spread between humans. However, the Andes strain linked to the current outbreak is one of the few known variants capable of person-to-person transmission through prolonged close contact.
Despite the growing international response, the WHO says the overall public health risk remains low and there is currently no evidence of widespread transmission.
