Public health officials on Wednesday, Sept. 17, confirmed the first human cases of West Nile virus in Los Angeles County this year.
According to the Los Angeles County Department of Public Health, four people were hospitalized with the virus between late July and late August. The unidentified patients lived in the Antelope Valley, San Fernando Valley and central Los Angeles areas.
“The first human cases of West Nile virus are an important reminder that we all need to take steps to prevent mosquito bites and mosquito breeding,” Dr. Muntu Davis, Los Angeles County health officer, said in a statement. “Mosquitos thrive in hot weather, increasing the risk of bites and mosquito-borne diseases.”
Davis said people should take steps to reduce exposure to mosquitoes, such as using insect repellents, removing items that hold standing water where mosquitoes can breed, and install door and window screens to prevent the insects from entering homes.
The virus is spread through the bite of an infected mosquito. Symptoms can include fever, headache, nausea, body aches and a minor skin rash. It can result in meningitis, encephalitis, paralysis and potentially death.
Los Angeles County has reported an average of 56 human cases of the virus annually over the past five years. Health officials said the actual number is likely much higher, since many infected people never develop any illness or symptoms and their cases are never reported.
