Learn about West Nile virus symptoms, risks, and prevention methods. The virus spreads via mosquitoes and can cause mild to severe neurological issues, especially in vulnerable populations. Awareness and mosquito control are key to safety.

Recognizing the Signs and Dangers of West Nile Virus Infection

West Nile virus spreads through mosquito bites, resulting in West Nile fever. Symptoms typically emerge within 2 to 15 days post-infection, although many individuals remain symptom-free, with approximately 80% showing no signs initially.

Initial symptoms include fever, headaches, and tiredness. More prominent indicators can involve muscle pain, nausea, loss of appetite, vomiting, and skin rashes. Some cases can lead to prolonged illness lasting several weeks or months.

In severe instances, neurological issues such as encephalitis or meningitis may develop, impacting the brain and nervous system. Symptoms include numbness, paralysis, visual disturbances, muscle weakness, seizures, confusion, neck stiffness, high fever, headaches, and disorientation.

People with preexisting conditions like hypertension, diabetes, kidney problems, or cancer are at higher risk. Transplant patients are also more vulnerable. Senior adults over 60 are prone to more intense symptoms and longer recovery periods.

Recovery duration can vary from weeks to months, and some neurological symptoms might be permanent. Although no specific antiviral drugs or vaccines are available, mild cases are treated with pain relievers, while severe cases require hospitalization with IV fluids and supportive care. Preventing mosquito bites is crucial to reduce infection risk.
