Symptoms and Signs. Early Lyme Disease. The disease starts after an infected tick expels its salivary gland and abdominal contents into the skin of a human. In about 60-70% of cases, a rash may develop at the site of the tick bite. This rash is most often circular with a clear edge, but oblong and other shaped rashes may occur as well in response to the tick bite. This rash is known as erythema migrans or EM. This rash usually starts about 3-30 days after the tick bite.
In most cases, the tick must be attached for 36 hours or more before the bacteria can be transmitted. Lyme disease does not spread from one person to another. Transfer of the bacteria from an infected pregnant woman to the fetus is extremely rare.lthough not routinely recommended, taking antibiotics within three days after a tick bite may be beneficial for some persons. This would apply to deer tick bites that occurred in areas where Lyme disease is common and there is evidence that the tick fed for 36 or more hours.
