Aims: Dracunculiasis is a neglected disease caused by a parasitic nematode, Dracunculus medinensis, also called the filaria of Medina. An outbreak of this disease occurred in the Salamat province in Chad in 2019, while the eradication of this disease worldwide was in its final stage. The outbreak occurred in the Bogam village (Liwi area), where this disease has never been reported in the past. The present work is aimed at identifying the factors that would have favored that outbreak, and the constraints that delay the eradication of dracunculiasis in Chad. Study Design: Retrospective study. Place and Duration of Study: The data retrospectively analyzed are those recorded during the census of patients by the Chadian National Guinea Worm Eradication Program (PEVG), from 2019 to 2020, and supplemented by those contained in the registers of previous years. The analyzes were carried out in N'Djamena, between July and November 2021, within the Laboratory of the Faculty of Medicine. Methodology: The census of patients was carried out during a survey from 2019 to 2020 by PEVG. These data have been supplemented by those contained in the registers of previous years. Data were first stored in a Microsoft (Excel 2007 Software) spreadsheet, then transferred to the SPSS version 20.0 Software, after removal of outliers and input errors. The Chi-Square test (χ2) made it possible to compare the percentages at the threshold of p |
