The open lesions can start to scab over and heal. The bull’s eye-type rash that can manifest around the area surrounding the open wound can occur nearly 3 weeks after the actual bite was sustained.  Approximately 45 days after the bite, the individual might observe scar formation in place of the scabbed-over ulcer.
