Track the 2026 Hantavirus Outbreak

What is Hantavirus?

Hantaviruses are a family of viruses spread mainly by rodents. They can cause varied disease syndromes in people worldwide. Each hantavirus serotype has a specific rodent host species and is spread to people via aerosolized virus that is shed in urine, feces, and saliva, and less frequently by a bite from an infected host.

Symptoms

• Fatigue and muscle aches
• Fever and chills
• Headaches and dizziness
• Nausea, vomiting, diarrhea
• Abdominal pain
• Shortness of breath (late stage)
• Coughing (late stage)

Transmission

Hantavirus is primarily transmitted to humans through:

• Inhalation of aerosolized particles from rodent urine, droppings, or saliva
• Direct contact with rodents or their waste
• Rarely, through bites from infected rodents
• Person-to-person transmission is extremely rare

Incubation Period

Symptoms typically appear 1 to 8 weeks after exposure to the virus. The average incubation period is about 2 to 3 weeks. Early recognition and medical care are critical as the disease can progress rapidly to severe respiratory distress.

Treatment

There is no specific treatment, cure, or vaccine for hantavirus infection. Treatment involves:

• Immediate hospitalization
• Oxygen therapy and mechanical ventilation
• Supportive care in ICU setting
• Early intervention is critical for survival

Prevention

• Avoid contact with rodents
• Seal homes to prevent rodent entry
• Use proper ventilation when cleaning enclosed spaces
• Wear protective gear when handling rodents
• Do not sweep or vacuum rodent droppings
• Use disinfectant before cleaning
