Hantavirus Symptoms: Early Detection Saves Lives
Hantavirus Pulmonary Syndrome (HPS) is a severe, sometimes fatal, respiratory disease caused by infection with hantaviruses. Understanding the symptoms and seeking prompt medical attention can dramatically improve outcomes.
Early Symptoms
Days 1-5 after exposure
Early symptoms of hantavirus infection are often mistaken for the flu or other common illnesses. This is the critical window for seeking medical help.
Fever
High temperature (38°C/100.4°F+)
Muscle Aches
Especially in thighs, hips, back, and shoulders
Fatigue
Severe tiredness and weakness
Headaches
Persistent and often severe
Dizziness
Lightheadedness and chills
GI Issues
Nausea, vomiting, diarrhea, abdominal pain
Late Symptoms
Days 4-10 — Medical Emergency
⚠️ Emergency Warning Signs
Four to ten days after the initial phase, late symptoms of HPS appear. These indicate severe respiratory distress and require immediate emergency medical attention.
Coughing
Dry cough that worsens rapidly
Shortness of Breath
Difficulty breathing even at rest
Tight Chest
Feeling of pressure or tightness in the chest
Fluid in Lungs
Lungs fill with fluid, making breathing impossible without medical intervention
