The health department said most of the state is under a high-risk warning for the mosquito-borne illness.
Last week, officials said mosquitoes in Bethany, Franklin, Greenwich, Madison, New Haven, Waterford, West Haven, and Weston tested positive for West Nile virus. About one out of 150 infected people develop swelling of the brain or brain tissue, that in some cases, can result in death.

In the meantime, they are reminding people to protect themselves from mosquito bites by using approved insect repellant, wearing light-coloured clothing, and removing standing water.
The City says that it has never had a confirmed diagnosis of West Nile virus in humans.

West Nile does not spread through coughing and sneezing or touching a live animal that's infected with the virus. "Current high levels of trapped mosquitoes and field surveillance surveys suggest a very active season for WNV". It was first found in the U.S.in 1999 and was detected in Arizona in 2003.
Empty water from mosquito breeding sites like buckets, unused kiddie pools or places where water collects. Fill tree holes with sand and seal with mortar and remove tree stumps that may hold water. Turn wading pools upside down when not in use. The mosquitoes become infected with WNV when they bite an infected bird.
Symptoms include headache, neck stiffness, disorientation, coma, fever, tremors, muscle weakness, vision loss, numbness and paralysis.More news: Rangers turn out lights on Diamondbacks
