1 doctor weighed in: Lyme disease bullseye how long does it last? 1 doctor weighed in Want a second opinion? While the length of time the bullseye may last it is usually fairly transient and is gone within 7-10 days at most.
To contract Lyme disease, an infected deer tick must bite you. The bacteria enter your skin through the bite and eventually make their way into your bloodstream. In most cases, to transmit Lyme disease, a deer tick must be attached for 36 to 48 hours. If you find an attached tick looks swollen, it may have fed long enough to transmit bacteria. Removing the tick as soon as possible may prevent infection.
