A mosquito found in a residential area of Menlo Park [California] tested positive for yellow fever.

The discovery prompted a response from vector control, which trapped 3 adult mosquitoes carrying the disease, along with 14 infected larvae.

Yellow fever is typically found in the Southeastern United States.

So far, there had been no reports of humans contracting yellow fever in the area.

[2] San Mateo County Mosquito and Vector Control District response

This [above] information is false. I know because I'm writing from the Vector Control District that serves Menlo Park (San Mateo County). _Aedes aegypti_ mosquitoes have been found, but no virus has been detected at this time.

[The above unfortunate and inaccurate report on yellow fever in California's San Francisco Bay area requires immediate correction. There is no yellow fever virus in the USA in California or in the southeastern states. The vector mosquito, _Aedes aegypti_, is present, but the yellow fever virus is not.

ProMED thanks Brian Weber for his 1st hand observation and comments. He mentioned that the district has an ongoing intensive surveillance and control campaign to eradicate _A. aegypti_ from the district. ProMED wishes them success.

A map showing the location of the 3 counties in California where _Aedes aegypti_ mosquitoes have been detected can be accessed at http://www.digital-topo-maps.com/county-map/california.shtml, and a map of California at [. - Mod.TY]

California residents cautioned to look out for yellow fever mosquito

The yellow fever mosquito, or Aedes aegypti ? a white polka-dotted bug that bites during the day and can lay its eggs in less than a teaspoon of water ? was first detected in June in Madera.

"We were shocked," said Leonard Irby, district manager of Madera's abatement program. "We never expected this mosquito in California."
An eradication effort was launched that included agents going door to door to warn people about standing water. But soon the mosquito was found in Clovis and Fowler. It turned up in August in the Bay Area's San Mateo County, and this week in Fresno. Officials are spraying insecticide around infected homes.
...
"There is no evidence of aegypti in Los Angeles. But you can never say with 100% certainty," he said. "Our brother and sister agencies in the Central Valley are being very aggressive and we're on high alert."
...
"Presently, dengue, yellow fever and chikungunya do not occur within California," Dr. Gilberto Chavez, deputy director of the California Department of Public Health's Center for Infectious Disease, said in an email. "There is presently no risk of these diseases being acquired locally and traveling within the state."

But the state is warning the medical community to be on the lookout for cases.
