A Covid expert says children are driving an 'uptick' in Covid cases that is contributing to a 'rapidly changing' national picture when it comes to the Omicron variant.
UK epidemiologist and professor Tim Spector was speaking on BBC Radio 4's Today programme on Monday (January 24) about how his optimism from a couple of weeks ago has been challenged.
Prof Spector is the co-creator of the ZOE Covid Symptom App and said his optimism was based on how the app had shown a peak of around 210,000 cases a day based on lateral flow and PCR tests combined before dropping to around half of that.
