Mosquitoes in 40 Connecticut towns have now tested positive for West Nile virus. The Department of Public Health says that mosquito pools in Danbury, Easton, Monroe, and Weston are among those that have tested positive for the virus. The virus typically causes fever, headache, drowsiness, nausea and a rash. Two human cases of West Nile-associated illnesses have been identified this year in Connecticut. There have been 136 cases diagnosed since 2000, with three deaths. Officials advise residents to repair window and door screens, empty standing water from gutters, buckets, pool covers and other places regularly.
