And for the first time, the Government is now encouraging people to wear face masks in public and enclosed spaces.
However, people can make their own masks at home.
But when should we wear face masks and will it be law enforced? North Ireland also advises residents to cover their faces in spaces where social distancing can not be followed whilst Wales does not recommend any coverings. This applies when using public transport, such as trains, buses and metro systems, or when visiting shops.
"Face-coverings should not be used by children under the age of two, or those who may find it hard to manage them correctly, for example primary age children unassisted, or those with respiratory conditions".
"Homemade cloth face-coverings can help reduce the risk of transmission in some circumstances".
Health Minister Jo Churchill said: "At all times our strategy for keeping the public and the NHS safe during this crisis has been guided by the science".
This is aimed at preventing people who have the virus - with no symptoms - from passing it on to others.

"The most effective means of preventing the spread of this virus remains following social distancing rules and washing your hands regularly. It does not remove the need to self-isolate if you have symptoms".
If you are taking care of a person with COVID-19. These droplets can also be picked up from surfaces by touch and subsequently from touching the face. "Other measures such as physical distancing and hand hygiene should be adopted".
Evidence shows a face covering can help in reducing the spread of droplets and therefore potentially infecting others, and could help to reduce the spread of infection as lockdown measures start to be lifted.
The UK government has given advice on wearing face masks outside.
While the Prime Minister has insisted that social distancing "must be maintained", he did not mention the use of face coverings during his address to the nation.
Brits should wear face coverings in public spaces where social distancing is not always possible, Boris Johnson's government has announced.
It's just a bunch of token gestures to appear to have the illusion that things are under control and they have the safety of the public in mind. Cloth face coverings should fit snugly but comfortably against the side of the face be secured with ties or ear loops, include multiple layers of fabric allow for breathing without restriction, be able to be laundered, and machine dried without damage or change to shape.
