Introduction: The fight against diseases, especially those preventable by vaccination, is a priority for the world’s health authorities. Measles remains one of the main causes of infant and child mortality despite the availability of a safe and effective vaccine. Prior to the introduction of mass vaccination in 1980, measles caused nearly 2.6 million deaths per year.Method: Our study was cross-sectional, descriptive and analytical. It took place from 01 to 31 January 2024 in the San health district. The study population was measles cases recorded in the surveillance database from January 2021 to December 2023. The data collected were entered and analysed using SPSS 25 software. Results: Of the 117 notified cases of measles, 65 were confirmed by the laboratory and 7 by epidemiological link. The majority of cases were female, and the 1 to 4 age group was the most affected in terms of suspicion and confirmation. The average age was 3.9 ± 3.8 years. Of the confirmed cases, 71% had not been vaccinated. The majority of cases occurred during the dry season, with April recording the highest number (16 cases). There was a statistically significant link between measles and the season. Overall vaccination coverage was 81.67% for VAR1 and 45.90% for VAR2. Conclusion: During the study period, measles occurred epidemically in the San district. The highest incidence was recorded in 2022, with a total of 44 confirmed cases. Good vaccination coverage and protective measures during the dry season could help to reduce the incidence of this disease.
