*Pools of ticks were tested with quantitative reverse transcription PCR for the small segments of CCHFV RNA. A total of 138 pools, comprising 346 ticks collected from 103 camels, were tested for CCHFV. Only 3 pools of Hy. dromedarii ticks from Illizi were CCHFV positive; only the pool in bold, containing 5 male Hy. dromedarii ticks, generated a 465-bp fragment of the small segment using the endpoint RT-PCR. CCHFV, Crimean-Congo hemorrhagic fever virus; Ct, cycle threshold.
