Coronavirus case rates have reached their highest ever level in England, according to a recent study.
Two variants of Omicron - the BA.1 and BA.2 - caused twin peaks in the pandemic, one in January and another last month, according to data from Imperial College London's latest React-1 study.
The study conducted from March 8 to 31 found 6.37% of people in England had Covid during this period - the highest level for any period of the pandemic so far.
