It is ever more becoming recognised as a community wellbeing difficulty, and scientists have been racing to discover out if Omicron provides as massive a possibility of very long Covid as beforehand dominant variants.
The analyze from King’s is thought to be the very first educational study to present Omicron does not current as excellent a possibility of very long Covid, but that does not suggest very long Covid affected person quantities are dropping, the staff explained.

Whilst the analyze – revealed in The Lancet journal on Thursday – in comparison Delta and Omicron, Dr Steves explained prior function experienced confirmed no sizeable big difference in very long COVID possibility in between other variants.
Far more function was required to set up why Omicron may possibly have a reduced very long Covid possibility, the staff included.
