relapsing fever

Quick Reference

An infectious disease caused by bacteria of the genus Borrelia, which is transmitted by ticks or lice and results in recurrent fever. The first episode of fever occurs about a week after infection: it is accompanied by severe headache and aching muscles and joints and lasts 2–8 days. Subsequent attacks are milder and occur at intervals of 3–10 days; untreated, the attacks may continue for up to 12 weeks. Treatment with antibiotics, such as tetracycline or erythromycin, is effective.
