Prompt diagnosis and treatment can prevent complications and death. Location of exposure, identification of the specific tick vector, and evaluation of rash, if present, help identify the specific disease. Lyme disease presents with an erythema migrans rash in 70% to 80% of patients, and treatment may be initiated based on this finding alone. RMSF presents with a macular rash starting on the wrists, forearms, and ankles that becomes petechial. RMSF has a higher rate of mortality than other tickborne diseases; therefore, empiric treatment with doxycycline is recommended for all patients, including pregnant women and children, when high clinical suspicion is present. Testing patient-retrieved ticks for infections is not recommended. Counseling patients on the use of protective clothing and tick repellents during outdoor activities can help minimize the risk of infection. Prophylactic treatment after tick exposure in patients without symptoms is generally not re...
