Mosquitos are possible carriers of either yellow fever or dengue, and they are breeding now in California. Initially, they were detected in California's Central Valley communities, specifically in Madera and Clovis in June. This particular mosquito breed called the Aedes aegypti is busy growing in numbers especially in Fresno and Bay area.

Aedes aegypti is a vector responsible for transmitting a lot of tropical fevers like yellow fever and dengue and they are highly recognizable by its dark color and distinct white markings in the legs. The CDC (Centers for Disease Control and Prevention) stated that this yellow fever mosquito seeks out human blood as a meal and used to frequent water containers in order to hatch their larvae and complete the development cycle. Even a teaspoonful of water can aid in the breeding process.

California mosquito control agents are finding it a bit of a challenge in containing this problem. This news shocked most of the inhabitants and officials since these mosquitos are not a common sight in California. Only infected female mosquito bites can prove deadly. Though officials are quite sure that these are not yet observed in the said state, they are also aware that having a mosquito bite into a dengue-infected person can be an unfortunate event. Similar to a scenario across southern Florida, an outbreak happened due to the presence of bitten infected residents.

Symptoms of having dengue fever are headaches, body malaise and pains along with rashes very close to that of measles. Most cases of dengue are treatable but if left unrecognized, it can prove to be fatal. The other disease that might be brought by the mosquitos is yellow fever. One can experience jaundice and extremely bad flu-like symptoms. Though state officials are taking note of any potential cases, awareness among the medical community is highly encouraged.
