While on one hand, there's no transparent path of transmission linking Omicron to its predecessors, on the other, the variant has an unusual array of mutations, which evolved entirely outside the view of researchers, Nature reported.

Some estimate that up to 30 per cent of the COVID-19 infected people, including many who were never hospitalised, have persistent symptoms. US researchers have identified four factors that are linked to a person's risk of developing long lasting symptoms post a COVID infection.
