“…This inflection was prolonged by an evolution of the epidemiological curve toward abscissa axis, suggesting a reduction of the transmission and consequently a decrease of measles new cases which led to the end of the outbreak. Our findings support previous studies reporting that there is a long period between the occurrence of measles outbreaks and the implementation of vaccination response, and also the impact of vaccination campaigns on the spread of the disease [ 21 - 23 ]. Many factors contributed to the success of measles outbreak response in Madagascar.…”

Introduction on October 4 th , 2018, a measles outbreak was declared in Madagascar. This study describes the outbreak response in terms of coordination, case management, vaccination response and epidemiological surveillance. Methods data were collected using a line list and vaccination tally sheet. Serum samples were collected within 30 days of rash onset for laboratory testing; confirmation was made by detection of measles immunoglobulin M antibody. Results from September 2018 to May 2019, a total of 146,277 measles cases were reported which included 1394 (1%) laboratory-confirmed cases and 144,883 (99%) epidemiological link-confirmed cases. The outbreak affected equally males (72,917 cases; 49.85%) and females (73,233 cases; 50.06%). The sex was not specified for 127 (0.09%) cases. Case fatality rate and attack rate were high among children less than 5 years. Responses interventions include effective coordination, free of charge case management, reactive vaccination, strengthened real-time surveillance, communication and community engagement and the revitalization of the routine immunization. Reactive vaccination was implemented in different phases. A total of 7,265,990 children aged from 6 months to 9 years were vaccinated. Post campaign survey coverage was 95%, 96% and 97% for phase 1, 2, 3 respectively. Conclusion elimination of measles will be challenging in Madagascar because of low routine immunization coverage and the absence of a second dose of measles vaccine in the routine immunization schedule.
