Hantavirus 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 four to 10 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.
