Jefferson County officials have discovered Culex mosquitoes that have tested positive for the St. Louis encephalitis virus.

According to Jefferson County mosquito control, the mosquitoes were found in the Griffing Park area of Port Arthur. Mosquito control workers recently sprayed the area in order to kill mosquitoes that may be carrying the virus.

The St. Louis encephalitis has some of the same symptoms as the West Nile virus. Both display symptoms of fever, headaches, dizziness, drowsiness and memory loss.

People should take extra precautions which means wearing long sleeves and pants when outdoors, and using mosquito repellent.

Those most affected by the virus, will be the elderly, or those with compromised immune systems. Younger, healthier persons would most likely experience milder symptoms.
