The World Health Organization reports:

Between 1 January and 3 April 2023, a total of 2161 measles cases (848 laboratory-confirmed and 1313 clinically compatible [suspected]) have been reported across 18 of 38 provinces in Indonesia, primarily from the provinces of West Java (796 cases), Central Papua (770 cases), and Banten (197 cases).


In 2022, a total of 4845 laboratory-confirmed measles cases and six deaths (CFR 0.1%) were reported across 32 of the 38 provinces. The provinces mainly affected were Aceh (978 cases), West Sumatra (859 cases), Riau (500 cases), and East Java (459 cases). Annual trend analysis shows the number of cases reported annually in 2022 and currently in 2023 is higher than usual.

In 2023, among the 2076 confirmed cases with available age information, 95% (1978) were between 1 and 14 years of age. Among the confirmed cases, 75% had not received any dose of measles-containing vaccine (MCV), while 11% had received one dose, 10% had received both doses, and vaccination history was unknown for 3%. Among these 2076 cases, 100% (212) of those younger than 9 months old, 87% (47) 9-12 months, and 66% (1303) of those aged 1-14 years had not received any dose of MCV.

The current outbreak is mainly characterized by suboptimal population immunity– the vaccination coverage in Indonesia in 2020 was 87% for measles-containing-vaccine first-dose (MCV1) and only 65% for measles-containing-vaccine second dose (MCV2). In 2021, national coverage of MCV1 was 87%, and MCV2 was 59%, with variation in administrative vaccination coverage at the sub-national level; these data indicate a very high number of children are susceptible to measles infection.
