NHS Funding Bill

My constituency borders Heathrow, and many of my constituents will be working at Heathrow with the airlines and in many other roles. I appreciate that the risk may be low, but could the Secretary of State update the House on whether advice has been given to Heathrow and airlines on how to give advice to their staff who may have come into contact with people who might be affected so that everybody can be assured that all is being done and that any support they may need is available?
