WEST COVINA, Calif.—Mosquito samples tested positive for West Nile virus near Morgan Park in the city of Baldwin Park, as announced by the San Gabriel Valley Mosquito and Vector Control District on July 15.
West Nile virus, endemic to the San Gabriel Valley, is typically detected by local public health agencies during the summer months. Warm overnight temperatures contribute to increased mosquito populations and heightened disease activity.
The district emphasized that it will continue to monitor disease activity and control mosquito populations in public spaces through routine inspections and necessary treatments. However, residents should take personal precautions to protect their health.
“West Nile virus can be transmitted by the native Culex mosquito species, which is most active at dusk and dawn,” stated Tristan Hallum, the district’s director of scientific programs. “There is no cure or human vaccine for West Nile virus. Therefore, the best method of protection is to prevent mosquito bites and reduce potential mosquito sources.”
To reduce the threat of the virus in the community, the district urges residents to:
- Tip out stagnant water around the home weekly.
- Toss unused containers that can hold stagnant water.
- Protect against bites by using insect repellent containing any one of the following
