Netherlands
While Dutch residents are automatically insured by the government for AWBZ, everyone has to take out their own basic healthcare insurance (basisverzekering), except those under 18 who are automatically covered under their parents' premium. If you don't take out insurance, you risk a fine. Insurers have to offer a universal package for everyone over the age of 18 years, regardless of age or state of health – it's illegal to refuse an application or impose special conditions. In contrast to many other European systems, the Dutch government is responsible for the accessibility and quality of the healthcare system in the Netherlands, but not in charge of its management.
National Health Service (England)
The National Health Service (NHS) is the publicly funded national healthcare system for England and one of the four National Health Services for each constituent country of the United Kingdom. It is the largest single-payer healthcare system in the world. Primarily funded through the general taxation system and overseen by the Department of Health, NHS England provides healthcare to all legal English residents, with most services free at the point of use. Some services, such as emergency treatment and treatment of infectious diseases, are free for everyone, including visitors.
