About West Nile virus
West Nile virus spreads to people from mosquitoes that feed on infected birds, according to the Centers for Disease Control and Prevention.
There are no vaccines to prevent or medicines to treat West Nile virus in people, the CDC states. Thus, preventing mosquito bites is key.
Most people who become infected do not feel sick. Those who do develop symptoms may experience fever, headache, body aches, vomiting, diarrhea or rash. However, about 1% of all people infected with West Nile virus develop the more serious neuroinvasive form of the disease.
To minimize the risk of contracting West Nile virus, DCPH advises these steps:
- Drain standing water to minimize mosquito breeding sites. Examples include bird baths, flower pots and clogged rain gutters.
- Utilize mosquito dunks, or Bti briquettes, in standing water that cannot be drained.
- Dress in long sleeves and pants while outside and spray thin clothing with mosquito repellent.
- Use an EPA-registered repellent containing ingredients like DEET, picaridin or lemon eucalyptus oil 66.
