Constituents of mine who returned from mainland China were told to self-isolate, even though they showed no symptoms, and that if they developed symptoms they should go to accident and emergency or their GP. This is the opposite of the advice the Secretary of State set out in his statement and in answer to another hon. Member. It cannot be right, in terms of both public health and reassuring the public, to have contradictory advice. Will he make sure that the correct advice is given from now on, as far and as widely as possible?
