Severe Hantavirus Symptoms and Health Complications

As hantavirus progresses, it can severely affect the lungs and heart. Patients may develop coughing, chest tightness, rapid heartbeat, and serious breathing difficulties. The advanced stage is called Hantavirus Pulmonary Syndrome and often requires emergency medical care. Without timely treatment, severe cases can become fatal within a brief period.

As the disease progresses, patients may develop:

• Shortness of breath
• Fluid buildup in the lungs
• Rapid heartbeat
• Low blood pressure

Severe cases can become life-threatening within hours.

Hantavirus Pulmonary Syndrome has a high fatality rate if not treated quickly.
