Measles outbreaks continue to be recorded in several districts, sometimes two weeks after the vaccination campaign in Niger. In 2019, in Niger the number of suspected cases was 2,568 with 431 confirmed cases. This number was significantly high compared to the 1,445 suspected cases and 397 positive cases recorded in 2018. This was after several actions had been undertaken including the establishment of case-by-case measles surveillance, the strengthening of the expanded routine vaccination program with the introduction of a catch-up dose of the measles vaccine in children under one-year-old, strengthening communication activities. It was necessary to conduct a database analysis to characterize the epidemiology of measles in Niger and improve the surveillance system.
