LOS ANGELES - The Los Angeles County Health Officer today confirmed the first human death of West Nile virus (WNV) infection in Los Angeles County this year. The fatality occurred in one older adult male, who lived in the South Bay area, had pre-existing health conditions and was hospitalized at the time of death. To date, 13 WNV infections have been documented, including 6 asymptomatic blood donors. Several agencies in Southern California, including the Greater Los Angeles County Vector Control District (GLACVCD) and the San Gabriel Valley Mosquito and Vector Control District, have been cautioning residents that this year is a particularly active year for mosquitoes carrying West Nile Virus.
"While most people bitten by a mosquito are not exposed to West Nile virus, some individuals may become infected with this disease and may experience symptoms that can last for months, or even years, such as fatigue, malaise, and depression," said Jonathan E. Fielding, MD, MPH, Director of Public Health and Health Officer. "Taking a few simple precautions can greatly reduce the risk of mosquito bites, the primary pathway to human infection. West Nile can appear anywhere in Los Angeles County, or around the state, and we are urging people to take precautions, such as getting rid of pools of stagnant water around their homes, and using a repellent containing DEET when outdoors in mosquito prone areas, especially around dawn or dusk."
In 2012, 174 human cases of WNV were reported in Los Angeles County, the second highest count documented since 2004. Of those who showed symptoms, 85% required hospitalization and 4% were fatal. As of July 30, 2013, WNV has been detected in 118 mosquito pools and 141 dead birds in Los Angeles County. Seventy-five percent of dead birds and nearly half of mosquitoes were found in the South Bay, but WNV activity has been found in other areas across Los Angeles County. The wide-ranging distribution of our human cases demonstrates that the virus can affect any location in the county. Persons over 50 years of age and those with immunocompromising medical conditions are at increased risk of serious WNV infection, neuroinvasive disease and death.
