WEST NILE VIRUS POSITIVE MOSQUITO DETECTIONS 
SURGE IN THE SAN GABRIEL VALLEY 
Public health officials urge residents to take preventative measures against mosquito bites over theholiday weekend .
West Covina, Calif. (September 3, 2026) – The San Gabriel Valley Mosquito and Vector Control District (SGV Mosquito) has detected 
105 West Nile virus (WNV) positive mosquito samples across cities and unincorporated areas within its service area, year-to-date. 
While WNV is endemic to the region, disease activity has surpassed the district’s five-year average signaling a need for residents to 
take extra precautions while outdoors during peak mosquito activity hours. 
West Nile virus is spread through the bite of an infected Culex mosquito which is most active at dusk and dawn. Vector control 
technicians are actively monitoring and controlling known sources and canvassing for additional sources in communities with 
elevated mosquito activity. Additionally, district staff are conducting enhanced surveillance and increasing awareness and education 
around mosquito prevention and protection. 
“Although current WNV activity is higher than usual, our teams are purposely equipped to deal with this challenge,” said Director 
of Scientific Programs Tristan Hallum. “We strongly encourage residents to tip out any stagnant water around their homes, toss out 
any unused containers that can collect water, and protect themselves with mosquito repellent when outdoors during this holiday 
weekend.” 
While WNV disease activity fluctuates year-to-year, local and state agencies are also observing higher than average activity. Visit 
VectorSurv Maps for a comprehensive look at this year’s WNV activity throughout Los Angeles County and California. 
There is no human vaccine or cure for West Nile virus; residents must be proactive at preventing mosquito-transmitted diseases 
through prevention and protection. Follow the tips below to reduce mosquito activity to stay healthy and bite free: 
Eliminate standing water in clogged rain gutters, rain barrels, discarded tires, buckets, watering troughs, or anything that holds 
water for more than a week. 
Ensure that swimming pools, spas, and ponds are properly maintained. 
Change the water in pet dishes, birdbaths, and other small containers weekly. 
Report neglected swimming pools in your neighborhood to your vector control district. 
Follow the tips below to prevent mosquito bites: 
Apply mosquito repellent to exposed skin before going outdoors and reapply as recommended on the label. 
Wear insect repellent containing CDC and EPA approved active ingredients: DEET®, Picaridin, IR3535, or Oil of Lemon 
Eucalyptus. 
Wear light-colored, long-sleeved shirts and long pants.

About SGV MosquitoSGV Mosquito is one of five vector control districts in Los Angeles County. Year-round, the agency monitors stagnant water sources, such as 
gutters, storm drains, channels and non-functional swimming pools. The agency also routinely monitors populations of adult mosquitoes using 
traps and tests groups of adult female mosquitoes for the presence of WNV and other mosquito-borne diseases. In addition, the agency submits 
samples from dead birds, such as crows, for testing, which can provide insight into the spread of WNV.
About West Nile Virus 
According to the Los Angeles County Department of Public Health, West Nile virus (WNV) is spread by the bite of an infected mosquito. One in 
five individuals infected with the WNV, for which there is no cure, will exhibit symptoms that include fever, headache, body aches, nausea or skin 
rash. The symptoms can last for several days to months. One in 150 people infected with the virus will require hospitalization. Severe symptoms 
include high fever, muscle weakness, neck stiffness, coma, paralysis and possibly death. Those at greatest risk include seniors and individuals 
with compromised immune systems. People over 50 years of age and those with chronic health problems are at higher risk of severe 
illness. While not all mosquitoes carry this virus, the type of mosquito that spreads this virus is found throughout Los Angeles County.
