The Los Angeles County Department of Public Health has confirmed the first death in the county due to West Nile virus for the 2019 season.
The patient, a resident of the South Bay area, was hospitalized and died from WNV-associated neuro-invasive disease.
“West Nile virus continues to be a serious health threat to residents in Los Angeles County. We encourage residents to check for items that can hold water and breed mosquitoes, both inside and outside their homes, and to cover, clean or clear out those items. Residents should protect themselves from diseases spread by mosquitoes by using EPA-registered mosquito repellent products, especially during the peak mosquito season which lasts from June to November in Los Angeles County,” said Muntu Davis, MD, MPH, Los Angeles County Health Officer.
Humans get WNV through the bite of an infected mosquito. Most mosquitoes do not carry the virus; therefore, most people bitten by a mosquito are not exposed to WNV. Those who do get WNV may experience mild symptoms including fever, muscle aches, and tiredness. In some cases, especially in persons over 50 years of age and those with chronic medical conditions such as cancer and diabetes, severe WNV infection can occur and affect the brain and spinal cord causing meningitis, encephalitis, and paralysis. There is no specific treatment for WNV disease and no vaccine to prevent infection.
