Symptoms of WNV
Most people with WNV have no symptoms.
Some people develop mild flu-like symptoms, nausea and skin rash.
The infection usually goes away on its own without treatment.
The virus is not contagious. You only get it from being bitten by an infected mosquito.
Very young and elderly people, and people with conditions like diabetes are more at risk of developing severe infection.
Signs of a severe infection can include flu-like symptoms and also:
- muscle weakness
- confusion
- fits (seizures)
Severe WNV infections are treated in hospital. In rare cases it can lead to meningitis.
