St. Louis Encephalitis detected in Dawson County mosquitos

KEARNEY, Neb. (Press Release) - Two Rivers Public Health Department is reporting that mosquitoes testing positive for St. Louis Encephalitis virus have been found in Dawson County.

St. Louis Encephalitis virus is spread to people after they are bitten by a mosquito which has the virus.

Most people who are infected with St. Louis Encephalitis do not have symptoms. Those who do develop symptoms may experience fever, headache, nausea, vomiting, and tiredness. Some people may develop neuroinvasive disease such as encephalitis (inflammation of the brain), or meningitis (inflammation of the membranes that surround the brain and spinal cord).

Although not all types of mosquitos transmit St. Louis Encephalitis virus, the only proven method to prevent St. Lous Encephalitis virus is to protect yourself from being bitten by all mosquitos. Be especially cautious in the mornings and evenings because this is when mosquitoes are more active. Wear lightweight, long-sleeved shirts and pants. Be sure to wear insect repellent containing DEET, IR3535, Oil of Eucalyptus or Picaridin.
