Lyme disease is transmitted by deer ticks, which are only 1-2 mm long. Most cases occur in the late spring and summer. The first symptom is usually an expanding red rash that is often pale in the centre, known as a bull's eye rash. However, in many cases, no rash is observed. Flu-like symptoms are common, including fever, headache, joint pains, body aches and malaise. When the infection is treated promptly with an appropriate antibiotic, usually doxycycline or amoxicillin, the cure rate is high. Luckily, since the tick must be attached for 36 hours or more to transmit Lyme disease, most cases can be prevented by performing a thorough tick check after you've been outdoors.
