Poland is a country located in Central Europe. It is divided into 16 administrative subdivisions, covering an area of 312,696 square kilometres (120,733 sq mi), and has a largely temperate seasonal climate. The major cities include Kraków, Łódź, Wrocław, Poznań, Gdańsk, and Szczecin. Poland is bordered by the Baltic Sea, Lithuania, and Russia's Kaliningrad Oblast to the north, Belarus and Ukraine to the east, Slovakia and the Czech Republic to the south, and Germany to the west.
Poland's healthcare system is based on an all-inclusive insurance system. State-subsidised healthcare is available to all Polish citizens who are covered by this general health insurance program. However, it is not compulsory to be treated in a state-run hospital, as a number of private medical complexes exist nationwide. All medical service providers and hospitals in Poland are subordinate to the Polish Ministry of Health, which provides oversight and scrutiny of general medical practice as well as being responsible for the day-to-day administration of the healthcare system. In addition to these roles, the ministry is tasked with the maintenance of standards of hygiene and patient care.
The climate is mostly temperate throughout the country. The climate is oceanic in the north and west and becomes gradually warmer and continental toward the south and east. Summers are generally warm, with average temperatures between 18-30 °C (64-86 °F), depending on the region. Winters are rather cold, with average temperatures around 3 °C (37 °F) in the northwest and −6 °C (21 °F) in the northeast. Precipitation falls throughout the year.
