Health officials say 20 OH counties have reported West Nile virus activity in mosquitoes tested in a statewide surveillance.
Another human case of West Nile is reported in Mississippi.
West Nile virus is transmitted to humans by mosquitoes. Since 2000, 134 human cases of West Nile have been diagnosed in CT residents, including three fatalities.
Use a mosquito repellent with an EPA-registered ingredient such as DEET while you are outdoors. She was the first case in the county since 2015, when three people were tested positive for the virus. Symptoms of these infections include a severe headache, high fever, muscle weakness, neck stiffness, paralysis, possible confusion and disorientation, tremors, and even a coma.
The Centers for Disease Control and Prevention has additional information about West Nile virus and preventing mosquito bites here.
Those infected with Zika infections have relatively mild illnesses that are rarely fatal.
"[Clay County Mosquito Control's] plan and response to this positive test is to elevate mosquito control in the Keystone Heights area, as well as to continue on throughout the entire county", said Rollins.
Symptoms may last from a few days to a few weeks. Aedes aegypti is not found in CT but a related species, Aedes albopictus, has been identified in the southwestern area of the state and it is also considered capable of transmission of the Zika virus. The elderly and those with compromised immune systems are most at risk.
Make sure you have good screens on your windows and doors to keep mosquitoes out.
The health district said use mosquito repellent as directed on the package. Wear repellent and wear long sleeves and trousers at these times, or stay indoors.
Remove any standing water around your home and yard to prevent mosquito breeding. If it rains, the spraying will be done during the same hours Friday.
The health department routinely tracks mosquito-borne illnesses, including Zika.
