West Nile Virus Season Starts

'Bird flu' has likely made you more aware of dead birds in your area. In our mosquito control work, we think about dead birds seasonally each summer because of a different virus - West Nile virus.
West Nile virus occurs throughout California and is primarily a disease that birds and mosquitoes pass back and forth to each other. However, sometimes a mosquito bite can transmit West Nile virus to a person. While most of us will not get ill from West Nile virus, older individuals and people with compromised immune systems are at risk of becoming very ill from West Nile virus.
Our work during the summer months is particularly focused on reducing the risk of people in San Mateo County getting infected with West Nile virus. One way is through our storm drain catch basin program. Another is through testing dead birds for West Nile virus.
Not all birds that are infected with West Nile virus will get sick, but West Nile virus can make some birds - like crows, ravens, and jays - very sick and even cause death. Last year in San Mateo County, we detected West Nile virus in a record number of 37 dead birds.
(An important note as backyard chicken flocks become popular is that chickens do NOT get ill or die from West Nile virus infection.)
Starting on April 15, the California West Nile Virus Call Center will reactivate for calls about dead birds. If a dead bird is reported in San Mateo County, our District will pick it up and test it for West Nile virus. If a bird is positive, we set up mosquito traps around the location the bird was found to determine if there are West Nile virus-positive mosquitoes in the area.

Mosquito Awareness Week, April 13-19
Every April, California Mosquito Awareness Week aims to raise awareness and educate the public on effective mosquito prevention and bite reduction measures, thereby preventing the spread of diseases. Keep these tips in mind for helping have a mosquito-free summer:

- Dump standing water at least once a week to prevent mosquitoes from growing - this includes plant saucers, children's toys, wheelbarrows, and anything that can hold water. Even just a bottle cap of water can grow mosquitoes!
- Dress in long sleeves and long pants to avoid mosquito bites, especially if outside at dawn and dusk (when the mosquitoes that can spread West Nile virus are more active).
- When using insect repellent, use one that has an EPA registration number. Ingredients like DEET, picaridin, oil of lemon eucalyptus, and IR3535 are a few of the common ingredients in EPA-registered repellents. Learn more about insect repellents.
- Report biting mosquitoes to us! One of our staff will visit to help figure out where the mosquitoes are breeding and how to stop them. Call 650-344-8592 or fill out a service request online.
