This year's annual census recorded an unusually high population of mosquitos, according to the Health Department. However, four out of five people infected with West Nile virus will not show any symptoms.

The Greater Los Angeles County Vector Control District is a public health service agency formed under the authority of the California State Health & Safety Code.

"Because the floodwater mosquitoes are considered nuisance mosquitoes, they bite real hard, but the West Nile Virus, which is the Culex mosquito, doesn't bite that hard", Dindy said.

The California Department of Public Health as of July 18 reported that 20 dead birds, 582 mosquito samples, and one human tested positive for West Nile Virus across 16 counties in California.

WNV is transmitted to people and animals through the bite of an infected mosquito.

As part of the District's Integrated Pest Management program and Mosquito-Borne Disease Management Plan, the District will administer Ultra Low Volume (ULV) treatments by using ground and/or aerial equipment in and around areas where mosquito counts and virus activity have met treatment criteria. Common symptoms include fever, nausea, headache and muscle aches. The symptoms can last for several days to months.

The district reported there were 211 human cases and 11 fatalities in California past year.

In rare cases, severe illness including meningitis or encephalitis, or death, can occur. People who observe a sick or dying crow, blue jay, robin or other perching bird should contact their local health department, which will determine if the bird will be picked up for testing.

The Health Department asks people to take these precautions.

REDUCE: Make sure doors and windows have tight-fitting screens. Try to keep doors and windows shut.

Water left standing for more than a week in containers like flower pots, fountains and pet dishes, or in unmaintained pools, can become a breeding habitat for mosquitoes, health officials said.

There are no vaccines to prevent the virus in people, but residents can reduce the risk of contracting it during mosquito season by using insect repellent and wearing long-sleeved shirts and long trousers while outdoors.

REPORT: Report locations where you see water sitting stagnant for more than a week such as roadside ditches, flooded yards, and similar locations that may produce mosquitoes.
