Indonesia is currently facing a significant resurgence of measles, with the Ministry of Health reporting a staggering 10,453 suspected cases and 8,372 confirmed cases between January and early March 2026. Tragically, this outbreak has resulted in four fatalities. There have been 45 outbreaks across 29 districts in 11 provinces. This alarming trend highlights the critical role of vaccination disparities across different regions.
Endang Budi Hastuti, the Director of Immunization at the Ministry of Health, emphasized that the main factor contributing to the rise in measles cases is the uneven distribution of immunization coverage throughout the country. Measles is a highly infectious disease caused by the morbillivirus, a type of RNA virus that primarily affects the respiratory system.
The disease is notable for its high transmissibility, with a basic reproduction number (R0) estimated between 17 and 18, meaning one infected person can spread the virus to numerous others quickly. “Measles is transmitted through respiratory droplets from infected individuals, especially during coughing or sneezing, as well as via contaminated surfaces,” Endang explained during a recent webinar.
The incubation period for measles is relatively short, often going unnoticed initially. Typically, symptoms like high fever may appear about 15 days after exposure, with a characteristic rash developing around 18 days post-exposure. Common symptoms include:
- High fever
- Cough
- Runny nose
- Conjunctivitis
- Maculopapular rash
- Itchy skin
- In some cases, diarrhea
According to Endang, several factors increase the risk of contracting measles, the foremost being children who have not received the complete measles-rubella vaccination. “One of the biggest risk factors is children who have not or did not receive the full measles-rubella immunization. Other risk factors include close contact with infected individuals, poor nutritional status, and the failure to practice good hygiene,” she added.
Endang cautioned against underestimating measles as a trivial illness, as it can lead to serious complications. Common complications include:
- Pneumonia or lung infections
- Severe diarrhea leading to dehydration
- Middle ear infections that may cause hearing loss
- Encephalitis, which can be fatal
In terms of treatment, supportive care is typically provided, including vitamin A supplements and symptomatic relief to manage symptoms. Niken Wastupalupi, the Director of Health Promotion, reiterated that vaccination remains the most effective means of preventing measles. The government has established a vaccination schedule for measles-rubella, recommending the first dose at nine months and the second dose at 18 months of age.
“The measles-rubella vaccination is the most effective way to prevent transmission. Children must receive vaccinations according to schedule to build sufficient immunity against the measles virus,” Niken stated.
This surge in measles cases serves as a critical reminder that successful control of infectious diseases requires collaboration between health authorities, community organizations, and parents. “Without high vaccination coverage and adherence to healthy living practices, the potential for outbreaks of preventable diseases will continue to threaten public health,” she concluded.
The ongoing situation underscores the urgent need for public health initiatives focused on improving immunization rates and ensuring that all children receive timely vaccinations. As health authorities function to address these challenges, community education and outreach will be vital to prevent further outbreaks and safeguard the health of the population.
