Joe Biden was likely infected with the BA5 subvariant of Omicron, the current dominant Covid-19 variant in the US, according to his physician, who reported that the US president’s symptoms “continue to improve” after he tested positive on 21 July.
The BA5 subvariant of the highly contagious disease accounts for nearly 80 per cent of recent infections in the US, according to the US Centers for Disease Control and Prevention.
