West Nile Virus has been confirmed in 11 cities across the Valley

West Covina, Calif. (August 28, 2024) — The San Gabriel Valley Mosquito & Vector Control District (SGVMVCD/District) has confirmed 21 mosquito samples that tested positive for West Nile virus (WNV) to date. These samples have been collected across 11 cities in the San Gabriel Valley.

“As warm temperatures continue into September, so does mosquito activity,” said Director of Communications Anais Medina Diaz. “It’s important that residents continue taking precautions to protect themselves and their family against mosquito bites and mosquito-transmitted diseases like West Nile virus.”

While the District monitors and controls mosquito populations in public spaces, the most common sources that contribute to high mosquito biting activity can be found on residents’ yards and patios.

Additionally, residents must be proactive against mosquito bites by wearing insect repellent because there is no human vaccine or cure for West Nile virus. The Centers for Disease Control and Prevention recommend products with the active ingredients DEET, Picaridin, IR3535, or oil of lemon eucalyptus as being safe and effective against mosquitoes when used according to the label.

Mosquito control is a shared responsibility. The District urges residents to take an active role in reducing mosquito populations and the threat of WNV in their communities by taking the following actions to stay healthy and bite-free:

• Tip out stagnant water around the home weekly;
• Toss unused containers that can hold stagnant water; and
• Protect against bites by using insect repellent containing any one of the following CDC-recommended ingredients: Picaridin, DEET, Oil of Lemon Eucalyptus (or PMD), or IR3535.
