INTRODUCTION
Tick-borne relapsing fever is a usual cause of fever in West Africa. Except relapsing febrile episodes, there are no pathognomonic signs and diagnosis is difficult because Borrelia density in patient's blood is low.
CASE REPORTS
Tick-borne relapsing fever was revealed by the presence of spirochetes in a blood sample to search malaria in two men, 24 and 31 year-old, returned from Mali.
CONCLUSION
This diagnosis should be evocated in patients having fever after a trip in infested area, as malaria, both infections can be associated.
引言
蜱传回归热是西非发热的常见原因。除了反复发热发作外，没有特征性体征，且由于患者血液中疏螺旋体密度低，诊断困难。
病例报告
在两名分别为24岁和31岁、从马里返回的男子的血样中发现螺旋体，从而确诊为蜱传回归热，该血样原本是用于检测疟疾的。
结论
对于曾前往疫区后发热的患者应考虑这一诊断，因为疟疾和这种感染可能同时存在。
