West Nile Virus: A Growing Threat

What is West Nile Virus?

West Nile virus (WNV) is a mosquito-borne illness that can cause serious health problems, such as encephalitis and meningitis. It is spread by infected mosquitoes that have bitten infected birds.

How Do You Get WNV?

You can get WNV only from a mosquito that has been infected by biting an infected bird. WNV does not usually spread from person to person.

What are the Symptoms of WNV?

The symptoms of WNV can vary, but they can include:

- Fever - Headache - Body aches - Nausea - Vomiting - Diarrhea - Rash - Swollen lymph nodes

In severe cases, WNV can cause encephalitis or meningitis. These conditions can be fatal.

How is WNV Treated?

There is no specific treatment for WNV. Treatment is supportive and may include:

- Rest - Fluids - Pain relievers - Anti-inflammatory medications

How Can You Prevent WNV?

There is no vaccine to prevent WNV. However, you can take steps to reduce your risk of being bitten by mosquitoes, such as:

- Wearing long sleeves and pants - Using insect repellent - Avoiding areas where mosquitoes are common - Staying indoors during peak mosquito hours (dusk and dawn)

What is the Outlook for WNV?

The outlook for WNV depends on the severity of the infection. Most people (about 80%) who are infected with WNV will have no symptoms or only mild symptoms. However, about 1 in 150 people who are infected with WNV will develop severe symptoms, such as encephalitis or meningitis.

Conclusion

West Nile virus is a serious health threat, but it can be prevented. By taking steps to reduce your risk of being bitten by mosquitoes, you can help protect yourself from WNV.
