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.
Meningitis symptoms. Meningitis and septicaemia can kill in hours-know the symptoms. The first symptoms are usually fever, vomiting, headache and feeling unwell. Red ticks show symptoms more specific to meningitis and septicaemia and less common in milder illnesses. Limb pain, pale skin, and cold hands and feet often appear earlier than the rash, neck stiffness, dislike of bright lights and confusion.
