Singapore reports more infectious BA.2 Omicron variant; says hospitals coping well

Singapore has recently reported 198 cases of Covid-19 traced to the BA.2 Omicron sub-lineage, which appears to be more infectious than the more common BA.1, but hospitals are coping well in spite of the current wave infecting thousands of people daily, according to reports. A total of 150 BA.2 cases were imported infections and the remaining 48 were local cases since January 25, 2022. Investigations into the characteristics of BA.2, including immune escape properties and virulence, should be prioritised independently (and comparatively) to BA.1, said the World Health Organisation (WHO).
