Experts say Connecticut's tick population is increasing this season and features some new species. They say the increase is due to a variety of factors including shorter and warmer winters and longer and wetter springs and summers. The New Haven Register reports the state counted more than double the number of ticks through April 30 than it did last year. Adding to the challenge is that tick-borne illnesses can have symptoms resembling those of COVID-19. Experts urge people working or spending extended periods of time outdoors to check for ticks, remove them carefully and submit them to the state.
