A 50-year-old man has contracted the first human case of St. Louis Encephalitis in Clark County since 2007, according to the Southern Nevada Health District.
The man, who was hospitalized, had the more serious neuroinvasive form of the illness. Most people infected with the virus have mild symptoms such as a fever or headache and don't become seriously ill.
Symptoms of the more serious form include headache, high fever, neck stiffness, shaking, seizures and even paralysis and coma.
“With the increased number of St. Louis Encephalitis-positive mosquitoes in Southern Nevada this season, we are not surprised to receive confirmation of a human case of the illness. It is another reminder to the community to protect themselves from bites and check their homes and yards for mosquito breeding sources,” said Dr. Joe Iser, Southern Nevada District chief heath officer.
To date, St. Louis Encephalitis-positive mosquitoes have been identified in the 89002, 89005, 89011, 89012, 89014, 89030, 89074, 89081, 89101, 89103, 89104, 89107, 89108, 89117, 89118, 89119, 89120, 89121, 89122, 89123, 89128, 89130, 89131, 89134, 89135, 89143, 89144, 89145, 89146, 89147, 89149, and 89191 ZIP codes.
