Plans to make face coverings compulsory on public transport do not go far enough, the British Medical Association has warned.
From 15 June, bus and train commuters in England could be refused travel if they fail to comply with the measures – or face a fine.
But according to the BMA, this should be extended to all areas where social distancing is not possible.
BMA council chair Dr Chaand Nagpaul also questioned why the introduction of these measures has been delayed adding that the risk posed by coronavirus would be much less if the public starts wearing face coverings immediately.
He said: The BMA recently advocated the wearing of face coverings by the public several weeks ago in areas where they cannot socially distance and believes it is right that people should be required to wear face coverings on public transport.
Given there remains a considerable risk of infection, with thousands of new cases every day, wearing masks can reduce the spread of the virus.
Not only will this afford greater protection to the public, importantly it will protect the lives of the staff working on public transport who, as evidence suggests, are at greater risk of infection.
Dr Nagpaul has also called for the government to provide a supply of face coverings to the public, and offer advice on how they can be used correctly.
Face coverings can include scarves, a piece of cloth or a mask and certain travellers, such as young children and people with disabilities or breathing difficulties, will be exempt.
At the moment, passengers are advised to wear a face covering but are not prevented from boarding transport without one.
Announcing the plans, Transport Secretary Grant Shapps said we need to ensure every precaution is taken as England relaxes the lockdown further, and passenger numbers start to increase once again.
