What is Hantavirus Pulmonary Syndrome?
Hantavirus pulmonary syndrome is an infectious disease characterized by flu-like symptoms that can progress rapidly to potentially life-threatening breathing problems.
Several types of hantaviruses can cause hantavirus pulmonary syndrome. They are carried by several types of rodents. You become infected primarily by breathing air infected with hantaviruses that are shed in rodent urine and droppings.
Because treatment options are limited, the best protection against hantavirus pulmonary syndrome is to avoid rodents and their habitats.
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.
