First West Nile Virus Death Reported in L.A. County This Year

In 2024, a resident from the San Fernando Valley became the first reported death in Los Angeles County due to West Nile virus, a serious mosquito-borne illness. The L.A. County Department of Public Health confirmed that the individual succumbed to neurological complications associated with severe West Nile infection. This year, the county has recorded 14 confirmed cases, while the state has reported a total of 63 cases. The health department emphasized the importance of preventive measures against mosquito bites, especially for vulnerable populations. West Nile virus is primarily transmitted through mosquito bites, with infected birds serving as the main reservoir. Most individuals infected with the virus do not exhibit symptoms, but approximately 20% may experience mild symptoms such as fever and body aches. A smaller percentage, about 1 in 150, can develop severe neurological symptoms, which can lead to lasting damage or death. The health officer expressed condolences to the family of the deceased and highlighted the ongoing risks posed by mosquito-borne diseases. The virus was first identified in Africa and made its way to the U.S. in 1999, with California reporting its first cases in 2003. Since then, the state has seen over 300 deaths and thousands of cases. Other counties in California, including Santa Clara, Contra Costa, and Fresno, have also reported fatalities this year, indicating a concerning trend in the spread of the virus. Public health officials continue to urge residents to take precautions, such as using insect repellent and eliminating standing water around homes, to mitigate the risk of infection. The recent death serves as a stark reminder of the potential dangers associated with West Nile virus and the importance of public awareness and preventive measures.
