Julie Webster, Wirral s director of public health AT the peak of Wirral s third wave of Covid-19, more than 500 cases were registered in a single day, putting the NHS and social care under serious pressure. Julie Webster, Wirral Council s director of public health, told a meeting of the authority s adult social care and health committee this week just how high case levels were at the peak of the borough s third wave. While Wirral had around 30 cases per day at the start of December, as the second national lockdown was ending, 537 cases were recorded on just one day, January 4. Reflecting on the enormous number, Ms Webster said it was clear to see how Covid-19 had once again got a grip of the borough.
