Symptoms to Look For
Most people who are infected with the West Nile virus will not develop any type of illness. It is estimated that 20% of the people who become infected will develop West Nile fever having mild symptoms including:
- Fever
- Headache
- Body aches
- Occasionally a skin rash on the trunk of the body
- Swollen lymph glands
More severe infection (encephalitis) is less common and may be marked by:
- Headache
- High fever
- Stiff neck
- Disorientation
- Convulsions
- Muscle weakness
- Paralysis
- In very severe cases, death may occur
Protect against mosquitoes:
- Keep grass and shrubs trimmed. Mosquitoes take cover in shaded areas during hot sunny days
- Wear light coloured long-sleeved shirts and pants
- Use enough repellant to cover exposed skin or clothing. Do not apply repellant to skin that is under clothing. Heavy application is not necessary to achieve protection. If repellant is applied to clothing, wash the treated clothing before wearing again
- Repellants containing DEET have been proven to be the most effective. For casual use, products with 10% - 35 % DEET will provide adequate protection for most conditions. The American Academy of Pediatrics recommends that repellants used on children contain no more than 10% DEET. Always read and follow the directions on the label.
- Eliminate stagnant water in birdbaths, lily ponds and any other receptacles in which mosquitoes might develop
- Use screens on windows and doors
- If possible avoid outdoor activity at dusk and dawn when mosquitoes are most active
- Use yellow light bulbs for outdoor lighting purposes
Remember, summer time is fun time. With foresight and precautions, it can be an enjoyable time for everyone.
