West Nile VirusMay 19, 2004 For the past several summers, West Nile virus has been making headlines across the country. For many years, West Nile virus was confined to the Middle East and Europe but in 1999 West Nile virus infections have been reported in the United States. West Nile virus infections are transmitted to humans by mosquitoes. Only 20% of infected people actually develop the disease. Most cases of West Nile consist of nonspecific symptoms such as fever, fatigue, decreased appetite, headache, rash, or eye pain, but it can also cause heart and liver abnormalities. Only 1 in 150 cases develop severe neurologic problems. Many people with West Nile may not be diagnosed because most cases cause mild, nonspecific symptoms. The test for West Nile is available only through the health department. People who become severely ill with West Nile should be admitted to the hospital. West Nile can be prevented. Any stagnant water should be avoided, as this attracts mosquitoes. Insect repellant containing DEET is effective against mosquitoes and should be applied before going outside. It is particularly important to wear insect repellant if you are outside during dawn or dusk when mosquitoes are most active. For More Information Contact: |
