A Recovery HealthCert is a digitally verifiable proof of a past COVID-19 infection in Singapore. Foreign authorities will be able to scan the QR code on the Recovery HealthCert to digitally verify that the certificate is secure and has not been tampered with.
Some countries/regions may have certain policies or exemptions for travellers who had recovered from a past COVID-19 infection. You may be able to use your Recovery HealthCert as a proof of your past infection.
You are advised to check the requirements of your destination country/region before you travel, such as the type/format of proof accepted.
