Port Health Regulations
This article is a stub. Please feel free to expand it and make it more encyclopaedic.
Port Health regulations include
- Health Protection (Ships and Aircraft) Regulations 2013. 
- The Public Health (Aircraft) Regulations 1979.
These provide local authorities with certain legal powers, including the power to put a traveller from a country in which a serious disease is prevalent under surveillance, or to require them to be examined. They do not, however, include a power of detention or restraint. As failing to comply with a surveillance order is a crime, it is possible that the Serious Organised Crime And Police Act 2005 might allow arrest/detention/restraint if it is "necessary".
- Mental Health Act 1983
- Public Health (Control of Disease) Act 1984
- Mental Capacity Act 2005
- Section 47 of the National Assistance Act 1948
