Fig. 4. Location of cattle markets relative to seropositive sampling sites (human and cattle). (A) Triangles and squares indicate the location of the cattle markets in Foumban and Bangangte respectively. Red points represent cattle herders positive to CCHFV antibodies, while (B) illustrates a cattle market scene, demonstrating the density and proximity of herders and cattle coming together and comingling.
This study investigates exposure to the Crimean-Congo Haemorrhagic Fever Virus (CCHFV) in Cameroon, focusing on cattle herders, febrile patients, and cattle. The research highlights the presence of CCHFV antibodies in these groups, indicating prior exposure to the virus. Seroprevalence was notably higher among cattle herders (17.8%) than febrile patients (8.3%). The study also found 27.4% of cattle tested positive, with older and female cattle showing higher infection rates.
Ticks, the main carriers of CCHFV, were predominantly found on cattle, with species like Rhipicephalus annulatus and Amblyomma variegatum being common. Despite having general knowledge of ticks, herders lacked awareness of how tick-borne diseases like CCHF are transmitted and demonstrated poor preventive practices.
This study confirms CCHFV circulation in Cameroon, particularly in rural and cattle market areas, and highlights risks for those handling cattle. The study underscores the importance of tick prevention and monitoring livestock to reduce the spread of this deadly virus. Public health interventions, such as awareness campaigns and collaboration with veterinary services, are critical to minimizing exposure and preventing potential outbreaks.
