What is West Nile Virus?

West Nile Virus causes an infection which results in swelling of the brain.  In a small percentage of people infected by the virus, the disease can be serious, even fatal. 

How is West Nile Virus spread?

West Nile Virus is spread to humans by the bite of an infected mosquito.  A mosquito becomes infected by biting a bird that carries the virus.  Horses bitten by mosquitoes that carry can also become infected.  A human or horse that has the disease cannot spread the virus.  The risk of getting West Nile Virus is highest from late July through September. 

What is the treatment?

There is no specific treatment for West Nile Virus infection.  Doctors can only treat the symptoms associated with the virus. Those over 50 years of age and those with immune problems or other chronic illnesses are more likely to become seriously ill. 

What are the symptoms?

Most people show no symptoms or have mild symptoms of the disease.  Mild symptoms include fever, headache, muscle weakness, and body aches, often with skin rash and swollen lymph glands.  More severe cases of the disease include high fever, stiff neck, confusion, coma, tremors, paralysis and death. 

What can you do to protect yourself?

The best way to protect yourself is to minimize contact with mosquitoes by: 

• Eliminate standing water that collects in birdbaths, boats, buckets, tires, unused pools, roof gutters and other containers.
• Use insect repellants.  Insect repellants containing 20-30% DEET work best.  Follow label instructions carefully.  Do not use repellants on children younger than two years of age
• Maintain window and door screens to keep out mosquitoes.
• Limit outdoor activity primarily between dusk and dawn when mosquitoes are most active.
• Wear protective clothing such as long sleeved shirts and pants.
• Avoid areas where mosquitoes may be present (i.e. shaded, wooded, or wet areas).
