CNBC: WHO says new omicron BA.2 subvariant will rise globally, but scientists don’t know if it can reinfect people

The World Health Organization has said that the COVID-19 sub-variant Omicron BA.2, first found in January, is now expected to spread globally. According to research in Denmark, Omicron BA.2 is 1.5 times more contagious than the original Omicron BA.1. However, vaccines are still highly effective in preventing infection and severe illness. Also, there are no signs of Omicron BA.2 being more severe than the original mutation. Experts are still unsure on whether the new sub-variant can reinfect people who already had Omicron BA.1.
