Quarantine

===Hong Kong===
{{Wikisource|Prevention and Control of Disease Ordinance}}
Under the ''Prevention and Control of Disease Ordinance'' (HK Laws. Chap 599), a health officer may seize articles they believe to be infectious or containing infectious agents. All travellers, if requested, must submit themselves to a health officer. Failure to do so is against the law and is subject to arrest and prosecution.

The law allows for health officers who have reasonable grounds to detain, isolate, quarantine anyone or anything believed to be infected, and to restrict any articles from leaving a designated quarantine area. He/she may also order the Civil Aviation Department to prohibit the landing or leaving, embarking or disembarking of an aircraft. This power also extends to land, sea or air crossings.

Under the same ordinance, any police officer, health officer, member of the [[Civil Aid Service]], or member of the [[Auxiliary Medical Service]] can arrest a person who obstructs or escapes from detention.
