Mr Chua Kheng Wee Louis asked the Minister for Health since the revision of healthcare protocols from 11 October 2021, what is the number of (i) Health Risk Warnings (HRWs) issued, with the breakdown by cases which are identified by TraceTogether records, SafeEntry records, and household member of a COVID-19 positive case, respectively and (ii) cases that subsequently tested COVID-19 positive after a HRW is issued.
Mr Ong Ye Kung: Between 11 October 2021 and 31 January 2022, about 887,000 Health Risk Warnings (HRWs) were issued. Close to 60% were household contacts of COVID-19 positive cases, while the remainder were identified by TraceTogether, SafeEntry, or other forms of contact tracing. The proportion of HRWs who eventually tested positive for COVID-19 was 10%. Household contacts are more likely to be infected than workplace or social contacts picked up by TraceTogether.
