More info'Stratus' is now the most common Covid variant in Wales - with experts reporting two major symptoms. There has been a rise in Covid cases in recent weeks - partly driven by new mutations. Experts say this and the 'Nimbus' variant do not appear to pose any bigger threat than previous types of Covid. This compared to 189 in-patients and two in critical care in the previous week. Confirmed cases of positive tests increased 13.3% in hospital and non-sentinel GP practices in the most recent week (week 38) compared with 10.2% in the previous week.
