Garut Declares Measles Outbreak as Extraordinary Event with 110 Children Infected; Mass Immunization Launched to Contain Spread

Garut Regency in West Java, Indonesia, has declared an extraordinary event status due to a measles outbreak that has infected at least 110 people, according to local health authorities. The declaration follows laboratory confirmation of measles cases in the region, prompting an urgent public health response.

The Garut Regency Health Office reported that 102 individuals tested positive for measles based on laboratory examinations conducted by the West Java Provincial Health Laboratory (Labkesda). Of those confirmed cases, 60 people required hospital treatment due to the severity of their symptoms, although no deaths have been recorded in the outbreak so far.

Measles cases in Garut have been occurring since January through April 2026, with health officials noting a significant increase in transmission during this period. Yodi Sirojudin, Secretary of the Garut Regency Health Office, stated that the rise in cases led to intensified medical care for many patients, while others are gradually recovering under medical supervision.

In response to the outbreak, health authorities have launched a mass immunisation campaign, also known as Outbreak Response Immunisation (ORI), targeting children and vulnerable populations across community health centres (Puskesmas) and integrated health posts (Posyandu). The campaign aims to curb further spread of the virus by vaccinating those at risk, particularly in areas where immunity gaps have been identified.

Measles is a highly contagious airborne disease caused by a virus that can lead to severe complications, including pneumonia, encephalitis, and death, especially in unvaccinated children. The virus spreads easily through respiratory droplets when an infected person coughs or sneezes, and it can remain infectious in the air and on surfaces for up to two hours.

Global measles activity has been rising in recent years, with outbreaks reported in multiple regions worldwide. According to the World Health Organization, large outbreaks are possible when measles is introduced into communities with low vaccination coverage. In 2023, an estimated 10.3 million people were infected with measles globally, and the disease remains a threat in areas where immunisation rates have declined.

Health experts emphasize that two doses of the measles vaccine are highly effective in preventing infection and are routinely administered as part of childhood immunisation schedules. Maintaining high vaccination coverage is critical to preventing outbreaks and protecting individuals who cannot be vaccinated due to medical conditions.

The Garut Regency Government continues to monitor the situation closely, working with local health facilities to isolate confirmed cases, provide treatment, and expand vaccination efforts. Officials urge residents to participate in immunisation drives and report any symptoms of measles, such as high fever, cough, runny nose, red eyes, and a characteristic rash, to seek timely medical care.
