The extent of its distribution in the US is unknown but it is believed to be expanding. As of 2014, it has not been documented in Connecticut or anywhere else in the northeastern US. It was definitely not present in Connecticut 10 years ago. As of 2014, the tapeworm was documented in North Dakota, South Dakota, Iowa, Minnesota, Montana, Wyoming, Nebraska, Illinois, Wisconsin, Indiana, Ohio, and Missouri, and southwestern Michigan.
Regardless of where the worm has bee documented, its virtually impossible to have a tapeworm infection and not know about it after a month or two. Tapeworms cause a lot of symptoms once they reach a certain size and they are unlikely to go away without treatment. So, if you got a tapeworm as a child, you would still have it now and you would still have symptoms. This is an easy thing to deal with. Call your doc's office and get a lab order to analyze a stool sample for parasites, collect a sample, and drop it off.
