Wales is seeing a "resurgence" of Covid cases in communities which could be particularly dangerous for those with waning immunity who have not had their spring booster, the country's top doctor has warned. Dr Frank Atherton, the Chief Medical Officer for Wales, said the BA.5 variant of Omicron has overtaken BA.2 - which caused infection levels to reach an all-time high earlier in the year - as the most dominant strain. Scientists say BA.5 is around six times more infectious than the original Wuhan strain.
According to the latest weekly Covid infection survey from the Office for National Statistics (ONS), an estimated one in 20 people in Wales had the virus between June 24 and June 30 - up on the one in 30 reported the week before and way up on the one in 75 at the start of June. It means just shy of 150,000 people in Wales had the virus last week.
