Madagascar: Measles Outbreak - Oct 2018

Disaster types

Madagascar has been experiencing a measles outbreak since early October 2018. The outbreak started in the urban health district of Antananarivo Renivohitra (in the heart of the capital city, Antanarivo) on 4 October 2018 when three measles cases were confirmed at the Pasteur Institute of Madagascar (IPM) by serology. The disease then spread to other health districts (Tanà South, Tanà North and Ambohidratrimo) in Analamanga Region (where the capital city is located) and subsequently to other parts of the country. The Ministry of Public Health formally declared the measles outbreak on 26 October 2018.

As of 18 November 2018, a total of 3 239 measles cases have been reported, of which 182 were confirmed immunoglobulin M (IgM) positive and 3 057 were epidemiologically linked. No deaths have been reported to date. A total of 23 districts (out of 114) in 12 regions (out of 22) are currently in epidemic phase. The urban health district of Antananarivo-Renivohitra is the most affected, accounting for 84% (2 730) of all reported cases. The other health districts with high numbers of cases are Ambatondratrimo (6%, 200), Antananarivo-Atsimondrano (3%, 91). The remaining health districts have fewer cases..The current measles outbreak has occurred at a time when there is some resurgence of plague in the country, straining the public health response system. The ongoing political election, with the risks of social tensions and conflict, has also downgraded the response to these public health events. (WHO, 23 Nov 2018)

As of 26 November 2018, 4104 confirmed cases have been reported (207 lab-confirmed and 3 897 epi-linked) from 31 healths districts in 17 regions. No deaths were reported. The most affected district is Antananarivo Renivohitra with 3 080 confirmed cases. (WHO, 30 Nov 2018)
