Yellow fever mosquito found in Kern County

The yellow fever mosquito, Aedes aegypti, has been detected in Kern County by the Kern Mosquito and Vector Control District.

This mosquito is not native to California and is a known carrier of diseases such as dengue, yellow fever and chikungunya. 

At this time, one Kern County resident diagnosed with chikungunya and one resident diagnosed with dengue were exposed to the infections during travel outside of Kern County.

With the identifications of the Aedes aegypti mosquito in the community, there is a risk for acquiring these infections within Kern County.

"The public's help is needed to eradicate this mosquito population before it can become established in our community," said Dr. Jonah, Kern County Health Officer.

To assist in eradicating this mosquito and reduce the risk of being bitten by mostquitos, Kern County residents are urged to:

  • Report mosquito bites received during the day.
  • Also report any mosquitoes which match the following description: Aedes aegypti is a small, dark mosquito with white markings and banded legs. It may be active around dusk and dawn but bites most often during the day and often bites indoors.
