Each week during the spring and summer months, the State of Connecticut tests area mosquitoes for any viruses that they may be carrying. This month, there's good news and there is bad news.

First, the good news: During the last test during the week of July 7, the Connecticut Agricultural Experiment Station, which is the state agency responsible for trapping, identifying and testing mosquitoes for encephalitis viruses, tested almost 26,000 mosquitoes in the state and none of them tested positive for West Nile or Eastern Equine Encephalitis. The bad news, however, four mosquitoes tested positive for Jamestown Canyon virus.

According to ctpost.com, the mosquitoes that tested positive for this virus were only found in four Connecticut towns -- Fairfield at Sherwood Island in Westport, North Haven, West Haven and South Windsor. With the latest test results, it brings the total number of mosquitoes that have tested positive for the Jamestown Canyon virus so far this season to 13.

Keep in mind, this number is only mosquitoes that have been captured and tested, so the total number of mosquitoes that are actually carrying the virus could be higher.

The Jamestown Canyon Virus was first detected in Colorado back in 1961, and like the West Nile virus, it can cause mild flu like symptoms, but it can also lead to other illness including meningitis and encephalitis.

Don't panic just yet. Since the year 2000, there have only been 166 actual cases of the Jamestown Canyon virus reported nationwide, and that includes just two in Connecticut. If you think you may have symptoms, however, it's always a good idea to consult with your doctor.
