4. Wearing a face covering
The Government said we should wear a face covering when in an enclosed space where social distancing is not possible, and where you will come into contact with people who you do not normally meet. It’s especially relevant for short periods indoors in crowded areas for example, or on public transport or in some shops. Evidence suggest that wearing a face covering does not protect you. But, if you are infected but have not yet developed symptoms, it might provide protection for others you come into close contact with.
It's important to remember that face coverings do not replace social distancing or self-isolation.
