how long for meningitis to develop after tick bite
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.
