West Sulawesi Strengthens Measles Vaccination and Surveillance Efforts

Health officials in West Sulawesi Province are intensifying measles surveillance in Pasangkayu Regency following reports of increasing cases across Indonesia earlier in 2026. The proactive measures include epidemiological investigations aimed at quickly identifying and containing potential outbreaks, according to Dr. Nursyamsi Rahim, Head of the Health, Population Control and Family Planning Office (Dinkes P2KB) of West Sulawesi Province.

This enhanced surveillance is part of an effort to improve early detection through strengthening health surveillance systems and ensuring a rapid response to potential Extraordinary Events (KLB) of measles, Dr. Rahim stated. The provincial government is prioritizing the strengthening of basic healthcare services, with a particular focus on protecting future generations from preventable diseases through immunization.

Officials emphasize that the current efforts extend beyond routine administrative monitoring, serving as a crucial forum for aligning perspectives, identifying challenges on the ground, and anticipating potential cases of preventable diseases due to low immunization coverage. Measles is a highly contagious disease, necessitating a high level of vigilance and a swift response from all healthcare personnel and stakeholders in the region, Dr. Rahim added.

These developments align with broader national efforts to strengthen surveillance against vaccine-preventable diseases, as highlighted by the World Health Organization (WHO) in its support for Indonesia’s public health initiatives. WHO has previously collaborated with the Ministry of Health of Indonesia and local health offices to improve outbreak investigation, surveillance, and immunization efforts in regions facing measles transmission risks.

In related efforts, health authorities in Sumenep, a district on the eastern tip of Madura Island in East Java, successfully ended a measles outbreak through coordinated response measures. With suspected cases reaching 2,996 and 205 confirmed cases around August 2025, urgent intervention was undertaken to halt transmission and prevent further deaths. WHO teams conducted root cause analysis, epidemiological investigations, and advocacy sessions with key local leaders, while also supervising outbreak response immunization implementation and delivering on-the-job trainings for health workers.

Combined with community engagement and targeted immunization campaigns, Sumenep significantly improved case detection and boosted vaccine coverage to 96.1%. These coordinated efforts enabled the district to interrupt measles transmission and lift the outbreak status, demonstrating how rapid coordination and multisectoral collaboration can stop infectious disease outbreaks.

More recently, the Indonesian Health Ministry declared an “extraordinary occurrence” (KLB) of measles across seven regions in South Sulawesi, reflecting ongoing concerns about vaccine-preventable disease transmission in parts of the country. The declaration underscores the importance of sustained surveillance, timely immunization, and community engagement in preventing the spread of measles, particularly among young children who are most vulnerable to complications.

As Indonesia continues to address gaps in immunization coverage and strengthen its public health infrastructure, officials stress that maintaining high vaccination rates and robust surveillance systems remain critical to preventing the resurgence of measles and other vaccine-preventable diseases. Continued investment in healthcare workforce training, data systems, and community trust-building is seen as essential to sustaining progress toward measles elimination goals.
