Some studies have estimated that some face coverings can increase protection fivefold against respiritory droplets, which is the main transmission
route of the SARS-CoV-2 coronavirus.

Masks are crucial for health and social care workers looking after patients, and they are also recommended for family members who need to care for someone who is ill.

Ideally, both patient and carer should wear a mask.

Masks in the workplace will help with businesses meet the requirements of social distancing.

Masks in the retail environment – particularly when serving foods – are also becoming more common.

The UK government has recommended the use of face coverings in crowded places where physical distancing is not always possible, such as on public
transport and in shops.
