MENLO PARK (KCBS) — A deadly mosquito that hasn’t been widely seen in the Bay Area since the 1970s has been detected in San Mateo County.

It’s called Aedes aegypti and it was found in January at the Holy Cross cemetery in Menlo Park.

It’s the mosquito that spreads yellow fever, chicken fever, the dengue fever and other diseases. Officials call it “one of the worst most effective vectors of disease around the world.”

The mosquito is tiny and its bite is hardly noticeable. Unlike other mosquitoes, it bites during the day.

Another yellow fever mosquito was also discovered in Menlo Park last August.

Officials are asking homeowners in the area to check their yards for containers of standing water, including bird baths, so it can be eradicated quickly.

I checked the symptoms of Yellow Fever. According to the Centers for Disease Control:

• The initial symptoms include sudden onset of fever, chills, severe headache, back pain, general body aches, nausea, and vomiting, fatigue, and weakness. Most persons improve after the initial presentation.
• After a brief remission of hours to a day, roughly 15% of cases progress to develop a more severe form of the disease. The severe form is characterized by high fever, jaundice, bleeding, and eventually shock and failure of multiple organs.
