Singapore preschool records first infant measles case following enhanced containment measures
An 11-month-old infant has tested positive for measles at a Singapore preschool, marking the first such case since the Communicable Diseases Agency implemented stricter containment protocols. The infant was not yet eligible for vaccination and is currently recovering.
- An 11-month-old infant is the first preschool-based measles case reported since new CDA containment measures began in February 2026.
- Four close contacts were issued quarantine orders, which were later rescinded following vaccination or post-exposure prophylaxis.
- Health officials report that 87 per cent of measles cases in Singapore this year occurred in individuals who were not fully vaccinated.
SINGAPORE: The Communicable Diseases Agency (CDA) has confirmed a case of measles involving an 11-month-old female infant attending a preschool in Singapore.
This marks the first preschool-linked infection since the agency intensified measures to contain the virus earlier this month.
The CDA was officially notified of the infection on 17 February 2026. According to a statement released by the agency on 24 February 2026, this represents the fifth instance of an infant under 12 months contracting measles this year.
The infant was not yet due for her first dose of the measles, mumps, and rubella (MMR) vaccination.
Under the National Childhood Immunisation Schedule, the first dose is typically administered at 12 months of age.
Investigations by the CDA revealed the infant has no known recent travel history or contact with previously confirmed cases. The agency reported that the child is currently recovering well from the illness.
The CDA confirmed the infant was present at the preschool during her infectious period.
Consequently, the preschool has notified all parents whose children were in close contact with the patient. Epidemiological investigations into the source of infection are ongoing.
Among the identified close contacts, the majority were found to be up to date with their measles vaccinations. No quarantine orders were issued for these individuals, though they have been advised to monitor their health for symptoms.
Four close contacts were initially issued quarantine orders by the CDA. These orders were subsequently rescinded after the individuals received either a measles vaccination or post-exposure prophylaxis to prevent the onset of the disease.
The CDA has advised casual or non-close contacts to review their personal vaccination status.
These individuals are encouraged to seek medical attention immediately if they begin to display symptoms associated with measles.
The Early Childhood Development Agency (ECDA) stated on 24 February that it is working closely with the CDA and the preschool operator. The collaboration aims to ensure the continued well-being of all enrolled children and staff.
The ECDA has formally reminded the preschool operator to maintain strict compliance with infection prevention and control measures. All centres must adhere to the Early Childhood Development Centres Regulations and Code of Practice.
Regulations require that all enrolled children and staff members are immunised against measles according to national guidelines. Operators are mandated to verify documentary proof of vaccination or immunity for all workers prior to their employment.
In response to a rise in infections, Singapore introduced mandatory isolation for cases and stricter contact tracing in early February 2026.
January 2026 saw 11 recorded cases, a significant increase from two cases in January 2025.
The CDA emphasised that vaccination remains the most effective method for preventing measles. Data from the agency shows that 87 per cent of cases recorded this year involved individuals who were not fully vaccinated against the virus.
The MMR vaccine is described by the CDA as highly effective and safe. The agency noted that the vaccine provides long-term immunity once the recommended doses are completed, protecting both individuals and the wider community.
High vaccination rates are essential for maintaining herd immunity within the Singapore population. This collective protection is vital for those unable to receive vaccines, such as infants under 12 months and severely immunocompromised individuals.
The ECDA noted that preschools maintain regular health surveillance protocols, including daily temperature and health checks for everyone entering the premises. This includes all children, staff members, and visitors arriving at the centres.
Individuals who appear unwell or display symptoms of any infectious disease are prohibited from entering preschool premises. If a child develops symptoms while at school, they are moved to a designated sick bay away from others.
Parents are promptly informed to collect any child displaying symptoms of illness. Furthermore, the ECDA has reinforced that all preschool employees must take medical leave if they feel unwell to prevent potential transmission within the facility.
