West Nile Virus Surges in Southern Nevada: Seven Cases Reported and Mosquito Activity at an All-Time High
Seven cases of West Nile virus have been reported in Clark County, Nevada, as mosquito activity reaches record levels. Three of the seven people were diagnosed with the neuroinvasive form and hospitalized, while two others had the non-neuroinvasive form and recovered. The Southern Nevada Health District (SNHD) has confirmed that 267 mosquito pools tested positive for West Nile virus, including 8,578 mosquitoes from 36 ZIP codes. Additionally, fifteen mosquito pools tested positive for the virus that causes St. Louis encephalitis.
The increase in cases and mosquito activity is a cause for concern among health officials. SNHD advises residents to take precautions against mosquito bites by wearing EPA-approved insect repellent, wearing insecticide-treated clothing, and long sleeves and pants. Eliminating standing water around homes is also crucial in preventing the breeding of mosquitoes.
The first West Nile virus cases were reported in early July 2024. The symptoms of West Nile virus include fever, headache, body aches, nausea, and vomiting. In severe cases, it can cause inflammation of the brain (encephalitis) or inflammation of the membranes surrounding the brain and spinal cord (meningitis).
The Southern Nevada Health District urges residents to report mosquito activity by calling their surveillance program at (702) 759-1633. For more information, visit their website.
This surge in West Nile virus cases and mosquito activity is not unique to Clark County. Across the United States, there have been over 1,000 reported cases of West Nile virus as of July 2024. The Centers for Disease Control and Prevention (CDC) advises residents to take precautions against mosquito bites and stay informed about the disease.
The CDC also reports that most people who get bitten by positive mosquitoes will not develop symptoms, making it essential to remain vigilant and report any suspected cases to health officials. The elderly, young children, pregnant women, and those with weakened immune systems are at higher risk for severe illness from West Nile virus.
As the summer progresses and mosquito activity continues to increase, it is crucial that residents take precautions against the disease. By following simple steps like wearing insect repellent and eliminating standing water around homes, we can help prevent the spread of West Nile virus and protect our communities.
