A total of 59 cases of Crimean-Congo hemorrhagic fever (CCHF) have been detected in Russia since the beginning of this year, according to Natalia Pshenichnaya, deputy director for clinical and analytical work at the Central Research Institute of Epidemiology at Rospotrebnadzor.
The occurrence of this disease is typical for the southern regions of Russia, according to Shechennaya. 49 cases of infection were detected in 2021.
“In these latitudes, favorable climatic conditions are formed for the habitat of ticks of the genus Hyalomma, the main carrier and reservoirs of infection, as well as for the reproduction of the virus in them, the causative agent of this infection,” says Natalya Pshenichnaya.
Crimean-Congo hemorrhagic fever is a widespread disease caused by a tick-borne virus (neurovirus) follower buniferide family. CCHF causes severe outbreaks of viral hemorrhagic fevers, with a fatality rate of 10–40%.
Animals become infected by the bite of an infected tick and the virus remains in the bloodstream for about a week after infection, allowing the tick-animal-tick cycle to continue when another tick bites. Although a number of genera of ticks are capable of infecting CCHF, only ticks from the genus Hialoma It is the main vector.
CCHF is transmitted to people either through tick bites or through contact with infected animal blood or tissue during and immediately after slaughter. The majority of cases have occurred in people involved in the livestock industry, such as agricultural workers, slaughterhouse workers, and veterinarians. Human-to-human transmission is possible.
The virus is spreading in some countries in Africa, Asia, the Balkans, the Middle East, and southern European part of Russia.
