encouraging signs

These trends suggest that the tiered approach helped to curb infections in and that lockdown has added to this effect

As we approach a challenging time of year, it's even more vital that through our actions and behaviours we all play our part in helping to keep the virus at bay

It's really important in the run-up to Christmas that we keep the virus under control
