The Permanent Secretary for Health Doctor James Fong says in a full lockdown no one except essential service workers move and it will be absolutely illegal for someone to stand on the side of the road or in a public space.
He says the only people moving around will be the screening teams and ambulances taking sick people.
Doctor Fong also stresses that in order for them to go into full lockdown they need to sort out things like food supply and the pre-positioning of essential items.
