Mosquitoes spread serious diseases, like West Nile virus and Zika

Protect yourself and your family from mosquito bites.

  • Wear mosquito repellent when you’re outdoors. Use spray, wipes or lotion.
  • Keep mosquitoes from infesting your home and yard. Tip and toss containers that hold water.

It is important that LA County residents take actions to protect themselves from mosquito-borne diseases. Learn more about what you can do to keep yourself, your family and your community healthy.

West Nile Virus is in LA County and can
  cause severe illness, even death.

Everyone is at risk of West Nile virus infection, but people over 50 and those with existing health conditions are most at risk of serious illness and long-term health problems.

Zika Virus can cause serious birth defects.
Zika is spreading in Mexico, Central and South America, and the Caribbean. If you’re pregnant or plan to become pregnant, protect yourself from mosquito bites. Wait to travel to these areas until after your baby is born.
