Incidence and transmission dynamics of Crimean-Congo Hemorrhagic Fever Virus (CCHFv) in slaughterhouse environments: ELISA based detection and risk assessment

Abstract

This study investigates Crimean-Congo Hemorrhagic Fever Virus (CCHFv) transmission dynamics in a slaughterhouse environment. A total of 409 blood samples from indigenous animals and 61 butchers were analyzed using an Indirect enzyme-linked immunosorbent assay (I-ELISA). Slaughtered animal seroprevalence was 19.3%, higher in sheep (21.9%) than goats (13.8%). Butcher seroprevalence was 3.3%, with reasonable knowledge of zoonotic disease transmission. Significant association between butcher and animal infections was found, but logistic regression results were inconclusive, suggesting other transmission factors. Further research is needed to understand transmission mechanisms and develop targeted prevention measures.
