As of 15 June, wearing face coverings on public transport in England is now mandatory by law.
The UK government has said that some form of facial protection must be worn by commuters in order to travel on public trains or buses, with people facing fines or refusal of travel if they do not comply.
But what does the guidance say about children?
Do children need to wear face masks?
Face coverings should not be worn by children under the age of two, according to government guidance.
Disabled people and those who have breathing difficulties are also exempt from wearing them.
All other children can wear a face covering, but for those who are under the age of 11, wearing a covering on public transport is not mandatory.
However, all public transport users who do not fall into these categories must comply with the rules and wear a face covering while travelling.
When should face masks be worn?
Face coverings are required to be worn at all times on public transport as of 15 June.
Government rules also state that coverings should now also be worn when attending a hospital as a visitor or outpatient.
It is also advised that people wear a face covering in other enclosed public spaces where social distancing is not possible, and where you will come into contact with people you do not normally meet.
What sort of face covering should be worn?
The government has advised that scarves, or homemade cotton coverings, that cover the nose and mouth, and other bought masks that are not the same as those used by the health service are fine to wear.
Surgical masks should be kept for use by health professionals.
Officials have said that people can make a face covering at home, but added it is key to ensure it covers your nose and mouth.
How do I wear a face mask properly?
Government guidance states that a cloth face covering should cover your mouth and nose while allowing you to breathe comfortably. This can be as simple as a scarf or bandana that ties behind the head.
Before putting it on, you should wash your hands or use hand sanitiser and do the same after removing it.
Avoid touching your eyes, nose, or mouth at all times and store any used face coverings in a plastic bag until you have an opportunity to wash them.
Do not touch the front of the face covering, or the part of the face covering that has been in contact with your mouth and nose.
Once removed, make sure you clean any surfaces the face covering has touched and wash the covering regularly. The covering can be washed with other laundry, using your normal detergent.
When wearing a face covering, take care to tuck away any loose ends.
