Singapore Reports Fifth Infant Measles Case, First Preschool Infection Amid Rising Cases in 2026

SINGAPORE, Feb 25, 2026 — Singapore has reported a confirmed measles infection in an 11-month-old female infant, marking the fifth measles case involving infants under 12 months old so far this year, the Communicable Diseases Agency (CDA) announced on Tuesday.

The case — officially notified to health authorities on Feb. 17 — also represents the first instance in 2026 associated with a child attending preschool since enhanced containment measures were introduced.

According to the CDA statement, the infant was enrolled in a Singapore preschool and was present at the facility during her infectious period. She had not yet reached the age for her first dose of the Measles, Mumps and Rubella (MMR) vaccine under the national childhood immunisation schedule and is currently recovering well.

Health officials have since initiated epidemiological investigations and contacted the parents of children who were in close contact with the case. Of all the identified close contacts, the majority were either already up to date with their measles vaccination or were in the process of being vaccinated. No quarantine orders were issued for these vaccinated contacts.

However, four close contacts who were not vaccinated were initially placed under quarantine. These orders were rescinded once they received either vaccination or post-exposure prophylaxis.

The CDA has advised vaccinated close contacts to monitor their health and seek medical attention if symptoms develop, while casual or non-close contacts have been urged to check their vaccination status and remain vigilant for signs of infection.

The Early Childhood Development Agency (ECDA) has confirmed its awareness of the case and stated it is working closely with the CDA and the preschool operator to safeguard the health and well-being of all enrolled children and staff. The ECDA also reiterated the importance of compliance with infection prevention and control measures.

Preschools in Singapore are required to comply with daily health surveillance protocols, including temperature checks and screening for symptoms among children, staff, and visitors. Individuals exhibiting signs of infectious disease are not permitted to enter preschool facilities.

Health authorities emphasise that vaccination remains the most effective way to prevent measles infection. A large majority of the measles cases recorded this year occurred in individuals who were not fully vaccinated, according to CDA data. The MMR vaccine has been shown to be highly effective and safe, conferring long-term immunity when the recommended doses are completed — and helping protect vulnerable groups such as infants under 12 months and immunocompromised individuals
