Symptoms of West Nile Virus

West Nile virus (WNV) is a mosquito-borne viral infection that primarily affects birds but can also be transmitted to humans through mosquito bites. The majority of individuals infected with WNV do not experience any symptoms, while others may develop mild to severe symptoms.

Mild Symptoms

Most people who contract WNV will have mild symptoms, which can include:

• Fever
• Headache
• Body aches
• Fatigue
• Joint pain
• Swollen lymph nodes

These mild symptoms typically last for a few days to a week and resolve on their own without medical intervention.

Severe Symptoms

In rare cases, approximately 1 in 150 individuals infected with WNV may develop severe symptoms, which can include:

• High fever
• Stiff neck
• Severe headache
• Disorientation or confusion
• Tremors or muscle weakness
• Convulsions
• Paralysis
• Coma

These severe symptoms may last for several weeks, and some individuals may experience long-term neurological effects.

Seeking Medical Attention

If you experience any of the severe symptoms mentioned above, it is important to seek immediate medical attention. While there is no specific treatment for WNV, healthcare professionals can provide supportive care to alleviate symptoms and monitor for any complications.

It is worth noting that individuals with weakened immune systems, such as the elderly or those with underlying medical conditions, are at a higher risk of developing severe symptoms when infected with WNV.

Prevention is key in reducing the risk of contracting WNV. Taking measures to avoid mosquito bites, such as using insect repellent, wearing protective clothing, and eliminating standing water around your home, can significantly reduce the chances of infection.
