SINGAPORE: Three previously reported COVID-19 cases have tested positive for the new B117 variant and could be linked, the Ministry of Health (MOH) said on Tuesday (Jan 26).
"Whole genome sequencing and phylogenetic analysis conducted by the National Public Health Laboratory have revealed that three previously reported cases (Cases 59028, 59340 and 59351) have tested positive for the B117 variant, and could be linked," MOH said.
On Jan 5, Case 59028, a work permit holder who works at Azur at Crowne Plaza Changi Airport was confirmed to have COVID-19.
