Hantavirus symptoms: early signs and severe respiratory disease
Hantavirus symptoms can begin with non-specific illness and may progress quickly in severe cases. This page summarizes verified public health guidance in plain English.
Early symptoms
Early illness may include fever, fatigue, muscle aches, headache, dizziness, chills and gastrointestinal symptoms. These signs are not specific to hantavirus, which is why exposure history and clinical evaluation matter.
Respiratory warning signs
Severe disease can progress to cough, shortness of breath, chest discomfort and difficulty breathing. Anyone with possible exposure and respiratory symptoms should contact a healthcare professional or local public health authority.
