- The study reports the first verified cases of Crimean-Congo hemorrhagic fever (CCHF) in Malgobeksky District, Ingushetia, highlighting the role of Ixodidae ticks as the initial infection source.
- The virus was found in the blood of cattle and in specific tick species (Haemaphysalis parva and Boophilus annulatus) collected from them.
- The research raises concerns about expanding the CCHF risk area to include the piedmont steppes of the North Caucasus.
Article Abstract
The laboratory verified cases of Crimean-Congo hemorrhagic fever (CCHF) in the piedmont steppes of the North Caucasus (Malgobeksky District, Republic of Ingushetia) are first described. The source of the first infection was Ixodidae ticks; three subsequent sources were contacts with the bloody discharges from patients. CCHF virus genome was detected in the blood of the cattle from an epidemic focus and in the pools of the Ixodes ticks Haemaphysalis parva Neum., 1897 and Boophilus annulatus Say, 1821, taken from cattle. The problem of including the piedmont steppes of the North Caucasus into the CCHF nosological area is discussed.
