This study was carried out for the first time in the North-Western Democratic Republic of Congo (DR Congo) as part of the Viral Epidemiology in West and Central Africa (WAVE) program. Its dual aim was to identify and map the viruses responsible for African cassava mosaic in this part of the country. Cassava leaf samples were collected during a geo-referenced survey conducted from 1st February to 31st March, 2022 in three provinces: Mongala, Nord Ubangi, and Sud Ubangi. Molecular diagnostics were carried out to identify the viral strains associated with Cassava Mosaic Disease (CMD). The results showed the presence of African Cassava Mosaic Virus (ACMV) and East African Cassava Mosaic Cameroon Virus (EACMCV) in the study area. EACMCV was present in all provinces, while ACMV was only reported in the province of Nord-Ubangi. This study recommends good agricultural practices and participatory surveillance as a strategy for managing CMD in the Democratic Republic of Congo. Key words: Epidemiology, cassava, viruses, East African Cassava Mosaic Cameroon (EACMCV), African Cassava Mosaic Virus (ACMV).
