What are the symptoms of Hantavirus?
Symptoms usually appear between 1 and 6 weeks after exposure and may vary depending on the viral variant and the course of the disease. The onset is often nonspecific, which can make early diagnosis difficult.
Initial symptoms
Early symptoms are similar to those of many viral infections:
Respiratory symptoms
In variants associated with lung involvement, the following symptoms may develop after a few days:
Cough.
Shortness of breath.
Chest tightness.
In severe cases, acute respiratory failure may occur, requiring intensive care treatment.
Symptoms with renal involvement
In variants associated with renal syndrome, the disease may progress with:
- Reduced urine output
- Impaired kidney function
- Oedema (swelling, particularly in the legs or eyelids)
- In some cases, blood pressure alterations
In the most severe forms, acute kidney failure can develop. This is usually transient but requires medical monitoring and, in some cases, hospitalisation.
