人們何時應該佩戴口罩？When should people wear masks?
有呼吸道症狀時應佩戴合適的外科口罩。到訪醫療或高風險場所，應遵從場所及衞生防護中心最新指引；高風險人士到人多地方亦應考慮佩戴口罩。口罩類型及貼合會影響防護，不能把一般外科口罩當作防污染或防護所有風險的保證。Wear an appropriate surgical mask when you have respiratory symptoms. Follow current facility and CHP advice in healthcare or high-risk settings; high-risk people should also consider masks in crowded places. Type and fit affect protection. A general surgical mask must not be treated as guaranteed protection against pollution or every hazard.
口罩類型有什麼區別？What's the difference between mask types?
不同口罩的防護表現及使用要求不同，應按風險及官方指引選擇。佩戴時遮蓋口鼻，減少面部空隙；口罩不能取代手部衞生、通風及其他適當措施。Mask performance and use requirements vary. Choose according to risk and official advice, cover the nose and mouth and minimise gaps. Masks do not replace hand hygiene, ventilation or other appropriate measures.
