Tick not engorged/flat

The likelihood of transmission if attachment is <36 hours is extremely low

No prophylaxis required

Monitor for 30 days

Generally presents within 7-14 days of bite, up to 30 days.

70-80% of patients present with a classic Erythema Migrans (EM) rash which consists of a single erythematous, expanding, greater than 5 cm rash +/- central clearing at the site of the tick bite.

This may be associated with symptoms such as arthralgia, headaches, fatigue and fever.

If a person develops evidence of early Lyme disease, they should consult a physician and receive appropriate antimicrobial treatment (not prophylaxis).
