About CCHF

According to the World Health Organization, Crimean-Congo haemorrhagic fever (CCHF) is a viral haemorrhagic fever primarily transmitted by ticks. It may also be contracted through exposure to viraemic animal tissues during and immediately after the slaughter of infected animals. CCHF poses a significant threat to public health, as it can lead to epidemics, has a high case fatality ratio ranging from 10–40%, and can result in outbreaks within hospitals and health facilities. Furthermore, prevention and treatment of CCHF remain challenging. The disease is endemic across all of Africa, the Balkans, the Middle East, and Asia.
 
Initially described in the Crimean Peninsula in 1944 as Crimean haemorrhagic fever, it was later determined in 1969 that the causative pathogen was identical to one identified in 1956 in the Congo Basin. This connection between the two locations led to the current designation of the disease and virus.
