In underdeveloped countries, infectious diseases remain one of the most important public health challenges. Visceral leishmaniasis, also known as Kala-azar, is a lethal vector-borne parasitic disease with an increasing number of cases. However, it remains one of the most neglected diseases in the world. It is the most severe form of leishmaniasis and is endemic in 75 countries. Around 95% of the patients live in seven countries: Brazil, Ethiopia, India, Kenya, Somalia, South Sudan, and causes about 20,000-40,000 deaths per year of which 50-70% are children. In Central Africa, this pathology is little known and less documented, making it difficult to access information. We have performed this study to characterize the knowledge on the epidemiology of visceral leishmaniasis in Central Africa. We reviewed the literature on visceral leishmaniasis in Central Africa on the number of reported cases, identified parasites, reservoirs and vectors. The documents consulted came from WHO reports, publications of scientific journals, reports of research institutions and abstracts of scientific conferences consulted online on Pubmed and Google Scholar. The information covers the period from the first reporting of cases in each country until December 2020. The review of the situation of visceral leishmaniasis revealed that it is not a significant public health problem in Central Africa. However, a lot of work remains to be done especially surveillance and research in order to present the exact situation of the disease in this part of the continent. This work would include the underreporting of cases inherent to the weaknesses of the surveillance system in these countries, the clarification of the transmission dynamics of human visceral leishmaniasis, canine leishmaniasis, the identity of parasites and vectors.
