Evaluation of the epidemiological surveillance system of measles in health district II of Niamey from 2017 to 2019

Abstract

Context: in 2019, the health district II of Niamey in Niger recorded the highest number of measles cases (44.8%)
compared to other districts in the region. The objective was to evaluate the epidemiological surveillance system in
health district II from 2017 to 2019.
Methods: we conducted a descriptive cross-sectional study from September 19 to 28, 2020. Key players involved
in measles surveillance at the central, regional and health district II levels as well as in three integrated health centers
(CSI) were interviewed. We also collected measles surveillance data from 2017 to 2019 from a literature review.
The data were analyzed using Excel 2016 / Epi info 7.2.3.1 software.
Results: in total 28 actors were interviewed. And 88.9% found the performance of surveillance in the region to be
good despite shortcomings including the lack of equipment / consumables (44.45%), lack of personnel / delay in the response (44.45%). The implementation of measles surveillance at district II level is effective. Reporting
completeness was 100% and readiness 88.83%. The age group of 1 to 4 years is the most affected, at 47.25% and
the sex ratio M / F = 1.01. The three CSIs have a routine immunization coverage of 104.22%.
Conclusion: the system is satisfactory, it is considered useful, simple, average sensitivity, good data quality, good
responsiveness and good representativeness. Nevertheless, the incidence of measles remains high and shortcomings
have been reported by stakeholders. Strengthening material and human resources, improving the response and
vaccination strategies are recommended.
