Tick bite fever (Rickettsia conorii) is a disease which occurs commonly in South Africa. Clinical illness in the black African patient is however rare, despite high seroprevalence rates of antibodies against R. conorii reported from other areas of Southern Africa. We present two case reports of clinically apparent tick bite fever occurring in black South Africans, the first to be documented in sub-Saharan Africa, and examine possible explanations for the marked discrepancy between clinical illness and seroprevalence rates.
蜱咬热（康氏立克次体感染）是一种在南非常见的疾病。然而，尽管从南部非洲其他地区报告的针对康氏立克次体的抗体血清阳性率很高，但在非洲黑人患者中临床发病却很少见。我们报告了两例南非黑人出现临床明显的蜱咬热病例，这是撒哈拉以南非洲地区首次有记录的此类病例，并探讨了临床发病与血清阳性率之间显著差异的可能原因。
