If you share a room or live in a group dormitory, you should contact the person in charge, such as the landlord or dormitory manager, before moving in, to tell the truth about your whereabouts and health condition in the last 14 days, such as whether you have fever, cough, or breathing difficulties, etc. You also need to know the above-mentioned conditions of other people living with you, and move in after confirming that the other person is in good health. If conditions allow, one person should have one room. If conditions do not allow, at least one bed per person. It is recommended that shared spaces such as bathrooms, kitchens, and living rooms be kept open and ventilated. Before entering a shared space, wear a medical surgical mask and try to maintain a social distance of more than 1 meter from your fellow occupants.
