How long can quarantine last for close contacts without immunity?

Close contacts without evidence of immunity may be quarantined for up to 21 days, which aligns with the measles incubation window. MOH will advise on start and end dates, based on exposure. Keep vaccination records ready, follow testing or monitoring instructions, and avoid public places until you receive formal clearance.

What proof of immunity is generally accepted?

Proof usually includes documented MMR vaccinations or laboratory evidence of immunity. Keep your health booklet or clinic records on hand. If you lack records, consult a GP about catch-up doses or appropriate testing. Clear documentation helps officials assess risk quickly and may reduce the need for stricter restrictions.

Do adults need an MMR booster in Singapore?

Most adults with two documented MMR doses do not need a booster. Adults without records or with uncertain histories should speak to a GP about completing two doses. Travelers, healthcare workers, and caregivers of infants should confirm protection well before exposure. Your doctor can advise on timing and any special considerations.

What should employers do after the rule update?

Refresh sick-leave and isolation protocols, confirm how to report a case, and ensure PPE and cleaning supplies are available. Encourage staff to update vaccination records and enable flexible work for exposed teams. Share clear guidance on symptoms and return-to-work rules so operations remain stable if a case occurs.
