Evidence of Crimean-Congo Haemorrhagic Fever Virus Occurrence in Ixodidae Ticks of Armenia

Crimean-Congo hemorrhagic fever (CCHF) causes serious health problems in humans. Though ticks of the genera play a significant role in the CCHF virus transmission it was also found in 31 other tick species. Totally, 1412 ticks from 8 remote sites in Armenia during 2016 were sampled, pooled (3-5 tick...

Description
Summary:Crimean-Congo hemorrhagic fever (CCHF) causes serious health problems in humans. Though ticks of the genera play a significant role in the CCHF virus transmission it was also found in 31 other tick species. Totally, 1412 ticks from 8 remote sites in Armenia during 2016 were sampled, pooled (3-5 ticks per pool) and tested for the presence of CCHFV antigen using ELISA test. From 359 tick pools, 132 were CCHF virus antigen-positive. From 6 tick species, four species ( , , , ) were positive for the virus antigen and was the most prevalent (37.9%). and revealed no positive pools, but both revealed delectable but very low virus antigen titers. The highest infection rate (50%) was observed in , whereas rate of infection was 1 out of 17 pools. For the first time in the last four decades CCHF virus antigen was detected in Ixodid ticks of Armenia. This finding substantiates the role of in the disease epidemiology; however, the role of in the CCHF virus circulation in the country could not be excluded.
