Los Angeles County is seeing the highest number of West Nile virus infections in nearly a decade, public health officials said Monday.
As of this week, LA County reported 100 West Nile virus cases. Public health officials expect to see more infections as it is still early in the mosquito season, which typically runs from June to November.
Five infected people have died. And nearly all patients with West Nile virus experienced severe illnesses, including infections to the brain or spinal cord, according to the LA County Department of Public Health.
“Almost all patients have needed hospital care,” the health agency said in a statement.
The last time LA County reported such a high number of West Nile infections was 2017. Nearly 270 cases were reported for the entire mosquito season then.
“West Nile virus can cause serious illness, and the number of severe cases and deaths we are seeing this year is concerning,” said LA County Health Officer Dr. Muntu Davis. “We are still within the peak period for West Nile virus transmission, so it is important that everyone take steps now to protect themselves and their families.
West Nile virus is the most common mosquito-borne disease that affects residents in LA County, health officials said.
Health officials said there are multiple factors behind the unusually high number of West Nile virus cases, including temperature, moisture and humidity.
Residents were urged to stay vigilant to prevent mosquito bites and remove standing water in or near their homes.
- Wear Mosquito Repellent: Mosquito repellents can prevent mosquito bites. EPA-registered repellents containing DEET, picaridin, IR3535, 2-undecanone, and oil of lemon eucalyptus are the longest lasting and most effective. They are available as sprays, wipes, and lotions. Wearing long-sleeved clothes and pants when outside can also help reduce bites.
- Keep mosquitoes out of your home: Make sure that doors and windows have tight-fitting screens to keep out mosquitoes. Repair or replace screens with tears or holes.
- Prevent mosquito breeding: Eliminate standing water where mosquitoes can lay eggs.
