Singapore has confirmed a measles case involving an 11-month-old girl attending preschool. This marks the first such instance since the Communicable Diseases Agency (CDA) enhanced measures to manage infections.
The infant, who was not yet eligible for the measles, mumps, and rubella (MMR) vaccination, had no recent travel history. She is recovering well. The CDA was notified of the case on February 17. This is the fifth measles case involving an infant under 12 months in 2026.
Epidemiological investigations are ongoing, with affected parents of close contacts notified by the preschool. Among identified close contacts, most were up to date with vaccinations or in the process of getting vaccinated, leading to the rescission of quarantine orders after receiving prophylaxis. Vaccinated close contacts are advised to monitor for symptoms.
The CDA emphasizes that vaccination is the most effective prevention against measles, noting that 87 percent of local cases this year occurred in unvaccinated individuals. The MMR vaccine provides long-term immunity and contributes to herd immunity, protecting vulnerable populations.
