Symptoms
By Mayo Clinic staffHantavirus pulmonary syndrome advances through two distinct stages. In the first stage, you may experience flu-like signs and symptoms that may include:
- Fever and chills
- Headaches and muscle aches
- Vomiting, diarrhea or abdominal pain
In its early stages, hantavirus infection is difficult to distinguish from influenza, pneumonia or other viral conditions. After three to seven days, more-serious signs and symptoms begin. They typically include:
- A cough that produces secretions
- Shortness of breath
- Fluid accumulating within the lungs
- Low blood pressure
- Reduced heart efficiency
When to see a doctor
The signs and symptoms of hantavirus pulmonary syndrome can worsen suddenly and may quickly become life-threatening. If you've been around rodents or rodent droppings and have signs and symptoms of fever, chills, muscle aches or any difficulties breathing, seek immediate medical attention.
