West Nile virus Facts
- The West Nile virus is a mosquito-borne virus that can cause encephalitis (an inflammation of the brain) or meningitis (inflammation of the lining of the brain and spinal cord) in humans and other animals.
- The virus is named after the West Nile region of Uganda where it was first isolated in1937.
- The virus appeared for the first time in the United States during a 1999 outbreak in New York that killed seven people.
How is the West Nile virus Spread?
- The virus is spread to humans, birds and other animals through the bite of an infected mosquito.
- A mosquito becomes infected by biting a bird that is carrying the virus.
- West Nile virus is not spread from person to person, and no evidence indicates the virus can be spread directly from birds to humans.
- Only a small population of mosquitoes are likely to be infected and most people bitten by an infected mosquito do not become sick.
- 1 in 300 people bitten by an infected mosquito get sick.
- 1 in 100-150 who get sick become seriously ill.
- 3 to 15 percent of those seriously ill die.
Symptoms of the Virus
- The symptoms generally appear about 3 to 6 days after exposure. People over the age of 50 are at a greater risk of severe illness.
- Milder symptoms include: Slight fever, headache, body aches, swollen glands and/or sometimes a skin rash.
- Severe symptoms include: High fever, intense headache, stiff neck, and/or confusion.
- Control mosquitoes from breeding around your home. Remove standing water from any item or area that can hold water. Standing water is a perfect breeding place for mosquitoes.
- Wear long and light colored clothing.
- Use insect repellent products with no ore than 20-30 percent DEET for adults and less than 10 percent for children.
- Spray repellent on your hands and then apply to your face; spray on clothing, as well. Be sure repellent is safe for human skin and clothing.
