Hon Dr DAVID CLARK: The provision of information at the airports is the thing that we are advised by the medical experts, the science, is the best and most effective thing we can do, because it makes sure that when people have the symptoms—if they have any symptoms—they know where to get help, to call Healthline; they know how to self-isolate effectively; they know how to do hand hygiene, cough hygiene, and other things that prevent the spread of this virus. So we have taken those measures that the clinical experts, the doctors, have recommended. At every point, we have made sure that our decisions have been informed by science.
