Open Web AppQu'est-ce que West Nile Virus?
West Nile Virus arrived in the U.S. in 1999 and has since become the leading mosquito-borne disease in the country. It's transmitted by Culex mosquitoes that bite infected birds. While 80% of infected people have no symptoms, severe cases can cause encephalitis or meningitis with long-term neurological effects. Age over 60 significantly increases risk of severe disease.
SymptĂ´mes
- Mild (West Nile fever): Fever, headache, body aches, joint pain, vomiting, diarrhea, rash
- Severe: High fever, severe headache, stiff neck, disorientation, tremors, seizures
- Neurological: Muscle weakness, vision loss, paralysis, coma
- Long-term effects: Fatigue, memory problems, muscle weakness (can persist months/years)
Transmission
Transmitted through bites of infected Culex mosquitoes. Rarely through blood transfusion, organ transplant, mother to fetus, or breastfeeding. NOT spread person-to-person through casual contact.
Période de Contagiosité : Not contagious person-to-person; can be in blood of infected person during illness
Prévention
- Use EPA-registered insect repellents (DEET, picaridin, IR3535, oil of lemon eucalyptus)
- Wear long sleeves and pants at dawn/dusk when mosquitoes most active
- Install/repair window and door screens
- Use air conditioning when possible
- Eliminate standing water (buckets, flower pots, bird baths, gutters)
- Change water in pet bowls, birdbaths weekly
- Treat or drain swimming pools, fountains
- Community mosquito control programs (spraying, larvicides)
- Avoid outdoor activities at dawn/dusk during peak season
