*Certain cases were those with positive culture, PCR, or suicide PCR results in blood or skin biopsy samples or with lymph node aspirates. Probable cases were those with identification by PCR and sequencing of the corresponding Rickettsia spp. in ticks, Western blot results demonstrating R. slovaca– or R. raoultii–specific antibodies, or a cross-absorption assay demonstrating specific antibodies against R. slovaca or R. raoultii. TIBOLA, tick-borne lymphadenopathy; DEBONEL, Dermacentor-borne necrosis erythema and lymphadenopathy.
†Denominators indicate the number of patients for whom the criterion was available.
‡Includes 14 patients previously reported (7).
§Temperature >37°5C.
¶Self-reported, persistent asthenia of 1 to 6 months.
#Self-reported persistent or relapsing asthenia of >6 consecutive months.
