Pasadena Public Health has reported the first case of West Nile virus in a Pasadena resident since 2022.
The case was confirmed on Thursday, Oct. 9, according to the department. West Nile virus is most often detected during warmer months when mosquitoes are breeding and can quickly spread viruses.
There is no vaccine or cure for the virus in humans so officials urged residents to take precautions.
“PPHD urges residents to take an active role in reducing the threat of West Nile virus by following mosquito prevention tips,” Manuel Carmona, director of Public Health, said in a statement. “The most effective way to stay protected is to prevent mosquito bites.”
The department recommended the following steps to reduce the presence of mosquitoes:
-Tip out stagnant water around the home weekly
-Toss unused containers that can hold stagnant water
-Use screens on windows and fix holes in screens
-Protect against bites by wearing protective clothing and using repellent containing the following recommended ingredients: Picaridin, DEET, Oil of Lemon Eucalyptus (or PMD), or IR3535.
The discovery comes as the San Gabriel Valley Mosquito and Vector Control District will conduct residential mosquito control applications via truck in Monterey Park and West Puente Valley.
It is being done to reduce the number of mosquitoes in the area and the risk of mosquito-borne disease. Vector control will use ultra-low volume adulticide and low volume larvicide applications to target mosquitoes at multiple stages.
Treatments will be done Monday, Oct. 13, and Tuesday, Oct. 14, between 12 a.m. and 5 a.m. Treatment in West Puente Valley will take place in the area between West Fairgrove Avenue and West Francisquito Avenue, north of North Hacienda Boulevard and south of North Sunset Avenue.
In Monterey Park, treatment will be done in the area of between West Floral Drive and the 60 freeway, east of Vancouver Avenue and west of Collegian Avenue, according to the district.
