West Nile Virus Infection
Prevention of West Nile Virus Infection
There is no vaccine to prevent West Nile virus infection in people. A vaccine is available for equine animals. Avoiding mosquito bites is key to preventing West Nile virus infection. To prevent mosquito bites, people should take the following precautions: Wear long-sleeved shirts and long pants. Stay in places that have air conditioning or that use window and door screens to keep mosquitoes out. Sleep under a mosquito net in places that are not adequately screened or air-conditioned. Use strong insect repellents—those with ingredients such as DEET (diethyltoluamide) or other approved active ingredients—on exposed skin surfaces. Treat clothing and gear withpermethrininsecticide (do not apply it directly to the skin). For children, the following precautions are recommended: Do not use insect repellent on infants under 2 months old. Do not use products containing oil of lemon eucalyptus (para-menthane-diol) on children under 3 years old. For older children, adults should spray repellent on their own hands and then apply it to the children's skin. Dress children in clothing that covers their arms and legs, or cover the crib, stroller, or baby carrier with mosquito netting. Do not apply insect repellent to the hands, eyes, mouth, or any cut or irritated skin.
