Records of human cases of Buruli ulcer collated through literature review and from surveillance programmes by national control programmes. For details on the review methodology, see Simpson et al 2019: Mapping the global distribution of Buruli ulcer: a systematic review with evidence consensus.
The surveillance datasets were compiled through routine surveillance for Buruli ulcer in Cameroon, Ghana, Nigeria and Togo.
Peer-reviewed literature was identified from searches of PubMed and Web of Science databases, updated on 06/08/2018. Additional publications were identified from reference lists of identified papers. We used the search terms (OR): “Buruli ulcer*”, (“Mycob* AND ulcer*”), “Bairnsdale ulcer”. There were no limits on publication date, study type, or location. We included English, French, and Spanish language publications. Publications were eligible for inclusion if they reported geographical locations with evidence of M. ulcerans infection in humans or animals, or detection of M. ulcerans in animal and environmental samples. There were no limits on publication date, participant population, study type or location. Articles that did not report original data were excluded. Studies that recruited patients from health facilities or used strains of M. ulcerans isolated from clinical samples were included in the evidence consensus framework only if patients’ home addresses were provided. Cases with recorded travel history to several endemic regions were excluded. If a dataset was duplicated in numerous papers, the most comprehensive was included.

Data contributed by the programme for National Yaws, Leishmaniasis, Leprosy and Buruli ulcer Control Programme in Cameroon are under the ownership of the Ministry of Health in Cameroon and their use is subject to the approval of the Ministry of Health.
