West Nile Virus Update as of October 4, 2024

Summary

As of October 4, 2024, there have been 709 locally acquired West Nile virus (WNV) cases reported in Europe during the 2023 transmission season. The majority of these cases have been reported in Greece, Italy, and Serbia.

WNV is the most common mosquito-borne disease in Europe. It is typically transmitted to humans through the bite of an infected mosquito. Symptoms of WNV can range from mild to severe, and can include fever, headache, muscle aches, nausea, vomiting, and rash.

There is no specific treatment for WNV, but most people recover fully within a few weeks. However, in some cases, WNV can lead to serious complications, such as encephalitis (inflammation of the brain) and meningitis (inflammation of the membranes that line the brain and spinal cord).

Prevention

There are a number of things you can do to protect yourself from WNV, including:

• Using insect repellent containing DEET, picaridin, IR3535, or oil of lemon eucalyptus
• Wearing long sleeves and pants when outdoors
• Avoiding outdoor activities at dawn and dusk, when mosquitoes are most active
• Making sure your home has screens on all windows and doors
• Removing standing water from your property, where mosquitoes can breed

Treatment

There is no specific treatment for WNV, but most people recover fully within a few weeks. Treatment is supportive and may include rest, fluids, and pain relievers.

Outlook

The outlook for people who contract WNV is generally good. Most people recover fully within a few weeks, and there are no long-term effects in most cases.

However, in some cases, WNV can lead to serious complications, such as encephalitis and meningitis. These complications can be fatal, but they are rare.

Conclusion

WNV is a serious disease, but it can be prevented by taking a few simple precautions.

If you are experiencing symptoms of WNV, it is important to see your doctor right away.
