Synopsis: This is a special episode of The Straits Times' video series The Big Story, hosted by Hairianto Diman and Olivia Quay. The Big Story gets an expert's take on Singapore's growing number of Covid-19 infections driven by the newer Omicron subvariants BA.4 and BA.5. These strains have contributed to a 23 per cent week-on-week increase in community cases, the Ministry of Health said on Tuesday night (June 21). About 30 per cent of the cases in the community in the past week were cases with BA.4 and BA.5 subvariants, as compared to 17 per cent, 8 per cent and 3 per cent for the previous three weeks respectively.
