Abstract

Introduction: Measles is a vaccine-preventable disease. In Côte d'Ivoire, reported cases have increased from 372 in 2019 to 600 in 2020, with outbreaks each year despite being under epidemiological surveillance. The health district of Touba has recorded 158 suspected cases, including 28 positive cases. As no in-depth analysis was conducted in this health district, the objective of this study was to analyze measles epidemiological surveillance data from 2021 to 2023.
Methods: A cross-sectional descriptive study of measles epidemiological surveillance data from January 1, 2021 to December 31, 2023 in the Touba Health District by looking at the completeness, internal consistency and external consistency of the data. After database clearance, the analysis was carried out using the Epi Info 7.2. software, describing measures of central tendencies, proportions, incidences for sociodemographic and laboratory characteristics.
Results: The database counts 5530 cells, with 429 empty cells (7.75%). Of the 158 measles cases reported, 34 cases (21.5%) have been confirmed. Evolution of positive cases according to the cases reported from 2021 to 2023 are respectively 20.2%, 20% and 21.6%. The year 2023 recorded the most confirmed cases (13 cases or 8.2%). The incidence per 100,000 inhabitants from 2021 to 2023 is 39, 49 and 47 respectively. The age group of 0-4 years old represents 65%, the male sex 59%, 88% of the unvaccinated and two deaths of confirmed cases. The sex ratio (M/F) is 1.4. All suspected patients and confirmed cases had received treatment and 97.5% had a favorable outcome. 
Conclusion: Confirmed measles epidemics every year in Touba. High incidence in the district with a predominance of the male sex. The vast majority of confirmed cases are unvaccinated. Increasing vaccination coverage. Ongoing analysis of surveillance data will help identify appropriate strategies for measles control and elimination.
