To follow up on the deer tick post from the other day. Many people ask, “why wait for the tick to be on 24 hrs before being concerned about Lyme transmission?” Well, there is an enzyme conversion in the tick that has to take place after the tick bites you for Lyme transmission to occur. This enzyme conversion takes 24 hours to complete. So, if you think the the tick has been on more than 24 hrs, contact your PCP.
