Symptoms

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.
