The Center for Disease Control and Prevention recently funded the Connecticut Agricultural Experiment Station (CAES) to collect and test for more organisms that cause human diseases, including Lyme disease, according to a recent article in the Wall Street Journal.

According to the article, CAES will begin testing for more tick species and for more pathogens.

Connecticut provides a number of fantastic resources to help prevent tick-borne diseases including this fact sheet on prevention and use of insect repellents, and a handbook on tick management by Dr. Stafford. The CDC page on lyme disease https://www.cdc.gov/lyme/index.html

The Wall Street Journal said that Connecticut reported more than 35,000 cases of diseases contracted through tick bites from 2004 to 2016, according to the CDC. That makes it the state with the fifth most cases, behind Pennsylvania, New York, New Jersey and Massachusetts.
