Bovine trypanosomiasis is a parasitic disease caused by protozoans of the genus Trypanosoma. The disease cause economic losses in livestock production. In order to determine the status of research on this disease in Côte d’Ivoire, we used the systematic review method and meta-analysis. Three electronics databases, namely Google Scholar, PubMed and CrossRef were used to search for publications on trypanosomiasis prevalence that met our inclusion criteria. Twenty five articles were identified, 11 of which met the inclusion criteria. Bovine trypanosomiasis prevalence of 2.99% (95% confidence interval [CI]: 2.96% – 3.01%) to 25.28% (95% CI: 25.17% – 25.38%) were recorded between 1960 and 2021. The analyses showed that the most infected regions were the Bagoue 11.26% (95% CI: 11.25% – 11.27%), Bounkani 14.94% (95% CI: 14.93% – 14.95%), Gbeke 10.34% (95% CI: 10.33% – 10.35%), Marahoue 13.79% (95% CI: 13.78% – 13.80%), Poro 8.50% (95% CI: 8.49% – 8.51%), and Tchologo 11.83% (95% CI: 11.82% – 11.84%).The most sensitive diagnostic method used was the polymerase chain reaction (PCR). The species of trypanosomes diagnosed were Typanosoma vivax 4.99% (95% CI: 4.97% – 5.01%), T. congolense 1.51% (95% CI: 1.49% – 1.52%), and T. brucei 0.61% (95% CI: 0.59% – 0.62%). Despite some variation, the prevalence of bovine trypanosomiasis in Côte d’Ivoire caused mainly by T. vivax has increased in the years between 1977 and 2017. Efforts to control tsetse and other mechanical vectors should also be put in place to minimize its transmission. Contribution: The authors studied the prevalence of bovine trypanosomiasis using the systematic review method and MA in order to determine the status of research on this disease in Côte d’Ivoire.
