To date, there has been no transmission of Zika virus by mosquitoes in San Mateo County or anywhere else within the United States. The risk of Zika virus in San Mateo County, and elsewhere in the US, remains extremely low.

West Nile Virus and Mosquito and Vector
Control Awareness Week, April 17th - 23rd


In August of 1999, two men checked into Flushing Hospital Medical Center with an unknown infection. Both men were over age 60, had similar symptoms, and were from the same neighborhood in New York City.

Days later, two more patients were identified with the same mysterious illness, then another four. They were very ill, with high fevers and paralysis of the arms and legs. Public health experts initially thought the patients had St. Louis encephalitis, but soon discovered that they were suffering from another mosquito-borne disease that had never before been seen in the United States: West Nile virus.

Today West Nile virus can be found in almost every state in the US, and in every county in California. Last year was the most deadly on record, with nearly 800 human illnesses and 53 deaths from West Nile virus in California. West Nile Virus and Mosquito and Vector Control Week recognizes the work done by mosquito and vector control and other public health agencies to reduce the risk of West Nile virus in California, and raises public awareness of the threat of West Nile virus and other mosquito-borne illnesses.

Spring into Action to Prevent Mosquitoes


Spring is here, and so are the mosquitoes. Here are a few simple steps you can take this spring to prevent mosquito problems on your property and reduce your risk of mosquito-borne illnesses like West Nile virus.

If you'll be saving rainwater to use later, remember that your rain barrel or other containers need to be screened, tightly covered, or completely emptied at least once per week. If you don't have a rain barrel yet, consider choosing one that comes already mosquito-proofed. The Bay Area Water Supply & Conservation Agency (BAWSCA) will even give you a $100 rebate toward the purchase of an approved rain barrel.

As we move into the dry season, avoid over-watering your lawn or garden. Check your yard for anywhere water may collect after watering or when sprinklers are on, including plant saucers, buckets or other containers, and folds in tarps or barbecue covers. Plan to move these containers away from areas that are watered, or empty them out at least once a week.

If your yard has a fountain, ornamental pond, water garden, or other water feature, make sure water is fully circulating. If you think mosquito larvae may develop, consider requesting a few mosquito fish. They're compatible with most other pond fish, and don't require any special care - you don't even need to feed them!

Need help checking your yard for mosquito problems? Give us a call at (650) 344-8592 or visit www.smcmvcd.org/help to request a free inspection.
