Covid cases have continued to rise in the UK, with an estimated one in every 20 people infected, figures from the Office for National Statistic suggest.
All age groups are affected, including the 75s and over, who are due a spring booster jab to top up protection.
Hospital cases are also rising, but vaccines are still helping to stop many severe cases, say experts.
An easily spread sub-variant of Omicron, called BA.2, is now causing most cases.
Recent easing of restrictions and waning immunity from the vaccines could be factors behind the rise too.
