Yes, for sure. I got a positive result from the Western Blot test for Lyme in mid JAN this year. I was having a lot of physical and nervous system issues arise in mid JAN, enough that I had to take 3 weeks off work. I didn't know what was going on, but it really hit me hard (symptoms vary a lot from person to person too) I honestly didn't think Lyme because it was mid-winter, but my PCP did a battery of blood work including one for Lyme and sent it to UVM. Came back positive--and since it actually showed up on the test(antibodies were still active in my bloodstream) its means it was acute and most likely got bit sometime in late NOV/DEC through early JAN. During that time had almost constant snow cover too, with a few breaks in total cover at times. So, yes- check yourself, kids, pets year round.
