While millions face a solitary Christmas in Tier 4, many folk will be able to meet up for Christmas Day. But you may well have concerns about Covid infection.
Here, Professor Azeem Majeed, Primary Care and Public Health head at Imperial College London, answers the key questions... How often should we wash or wash our hands?
Aim to get into a routine for handwashing. I would recommend doing it around every two hours during the daytime. What is your view?
Have your say in the comments section You should also wash your hands before and after any activity that might increase the risk of infection, such as handling food or after being in contact with other people.
