A West Nile Virus outbreak has been declared in Clark County. The Southern Nevada Health District declared the outbreak now that 28 cases have been reported in the county. Twelve more of them since August 8. “The West Nile virus activity we are seeing in our community is a serious public health concern,” said Dr. Joe Iser, Chief Health Officer of the Southern Nevada Health District. “I urge people to protect themselves from mosquito bites by using repellents whenever they are outdoors and to make sure they are eliminating standing water from around their homes.”
Nearly 1 in 5 mosquitoes tested in Nevada has tested positive for West Nile which is much higher than last years numbers.
Most people with the virus (eight out of 10) will have no symptoms or very mild symptoms of illness. About 1 in 5 people will develop mild symptoms which include fever with other symptoms such as headache, body aches, vomiting, diarrhea, or rash. Most people with this type of West Nile virus recover completely but fatigue and weakness can last for weeks or months. About one in 150 people who are infected develop a severe illness affecting the central nervous symptom such as encephalitis or meningitis.
