How do you get West Nile Virus

People get the West Nile Virus from bites from infected mosquitoes. Mosquitoes get the virus from feeding on infected birds.

How to avoid West Nile Virus

Dr. Huang said to use the 4 Ds to avoid being bitten. The 4 Ds are: 

  • Deet: Make sure you use insect spray with DEET or different EPA-approved repellents when outdoors. 
  • Dress: Loose fitting, long, and lighter colored clothes will help prevent mosquito bites when outside. 
  • Drain: Mosquitoes can lay eggs in standing water. The DCHHS recommends you treat or drain any standing water at your home or job.
  • Dawn to Dusk: Avoid going outdoors when mosquitoes are highly active.
