The Asian tiger mosquito, which was thought eradicated from the San Diego area 14 years ago, made a grand reappearance when it was found by the Department of Environmental Health on Sept. 22.

The mosquito, Aedes albopictus, can transmit yellow fever, chikungunya and dengue fever to people, though this is usually seen when people travel to the tropic, who contract the disease and return. It is also known to be infected with LaCrosse encephalitis viruses and West Nile virus.

To prevent mosquitos from establishing in the state, officials have warned people to dump out any standing water in or outside their house. Also to report to county vector control if people are bitten indoors during daytime, when Asian tiger mosquitoes feed. They are small with black with white markings, can breed in a small amount of water, and like urban areas and indoors.

The Asian Tiger mosquito is native to tropical and subtropical Southeast Asia. According to the DEH, the mosquito has been spreading across the state for the past year, and has infected communities in Los Angeles County. San Diego County has taken measures by monitoring traps, and handing out information to the public on how to prevent the mosquito from spreading.

People can avoid being bitten by dumping all standing water, wearing long sleeves and pants outdoors, use insect repellent, and report neglected and green swimming pools to the Vector Control Program at (858) 694-2888 or
