It’s time to think about protecting yourself from tick bites

Lyme disease has been a public health issue in Connecticut since 1975. While most human cases of Lyme disease are the result of the bites of tiny, infected immature ticks called “nymphs," which feed during the spring and early summer months, the adult black-legged tick known as a “deer tick” or Ixodes scapularis, is most active from late October through May. Therefore, it’s time to think about protecting yourself from tick bites.

Along with many other tick-associated diseases such as human ehrlichiosis and human babesiosis, Lyme disease can be readily acquired in any Connecticut town, particularly in areas that are wooded. In 2017, the State of Connecticut ranked fifth among states reporting Lyme disease with total 2,022 cases (confirmed and probable). That year, Fairfield County was reported to have the highest incidence rate of disease followed by New Haven County. In 2017, the Greenwich Department of Health Laboratory tested 457 ticks and about 24 percent of them were positive for the Lyme disease bacterium. About 3 percent were positive for the organism that causes babesiosis. Overall, examining infection rates by the life stage of the tick in this year, it was observed that 30 percent of the adult ticks and 10 percent of the nymph ticks (active May-July) were positive for Lyme bacterium.

 “The spring is important for awareness about Lyme disease since everyone is planting, raking leaves and/or taking part in some kind of outdoor activity," said Caroline Calderone Baisley, Director of Health. “By applying a few simple precautionary measures like checking for ticks on the body every day, avoiding tick-prone areas such as leaf litter and vegetation, and using insect repellent, everyone can still enjoy being outdoors. These measures will decrease the chance of being infected. It is also important to remember that pets can carry ticks into the home, so checking pets for ticks will greatly reduce the risk of ticks being carried indoors.  Pet owners should talk to their veterinarians about using a topical tick prevention product on their pet all year long."

It is also important to take note of other tick-borne diseases such as babesiosis. The State of Connecticut reported 252 confirmed cases of babesiosis in 2017. This number has increased from the year before.                                                                          

In an effort to raise awareness of this important health problem, the Greenwich Department of Health Laboratory will continue to provide public health literature and offer testing of ticks for the bacterium that causes Lyme disease and the protozoan organism that causes babesiosis. 

“Although a tick may test positive, it does not necessarily mean that you will get Lyme disease,” said Lab Director Doug Serafin. “Like any other screening tool, the process for testing ticks has a small margin of error and, specifically for these diseases, the tick must be attached for a period of time in order to increase a person’s risk. An engorged positive tick is much more likely to pass on the pathogen agent than those ticks that are not engorged. Tick testing is only one tool among many to assess a person’s risk of getting Lyme disease or other tick-borne diseases.” 

If a tick is found on a person – either dead or alive – it should be removed carefully with a long-nosed tweezer. The tick should be placed in a tightly sealed small plastic sandwich bag marked with the date and body site of the bite. The cost of tick testing is $65.00 until June 30, 2019, then increases to $68 from July 1, 2019 through June 30, 2020. Testing includes identifying the bacterium that causes Lyme disease and the protozoan organism that causes babesiosis.  Results are normally available within 7-10 days.
