Evaluation of the epidemiological surveillance of measles: Analysis of the Koulikoro health district database from 2012-2018

Abstract

Introduction: Measles is a febrile eruptive disease caused by a virus (Morbillivirus). The absence of measles analysis results in the district, led us to the analysis of measles epidemiological surveillance data from 2012 to 2018, the objectives were to describe the characteristics of the disease in time and person and to identify the factors associated with the occurrence of measles. Material and methods: We conducted a cross- sectional study, using the notification forms, the declaration book, the linear list and the laboratory files from 2012 to 2018, entered and analyzed on Epi Info 7.2. Results: In our study, we found n = 48 suspected cases from 2012 to 2018, of which 6% were positive (IgM +), the male sex was the most represented n = 27 (56) P = 0.38, the elderly were 15 years and over represented all positive cases (IgM) n = 3 (100) P = 0.0002. Subjects (suspected and confirmed) n = 6 were not vaccinated against measles P = 0.0002, the suspected and confirmed cases n = 31 (64.5) came from the city of Koulikoro. Conclusion: The analysis of the database, allowed us to find three suspected and confirmed cases in the district. Men were more concerned than women. All cases were at least 15 years old and none were vaccinated against measles. This suggest a reinforcement of routine immunization and a study over a longer period that may be help to identify the determinant factors. Keywords: Analysis, database, measles, Koulikoro, Mali
