All Erasmus students need to have valid health insurance while staying in Poland.
In order to use health care, which is free of charge, students must have valid European Health Insurance Card (EHIC). EHIC concerns students derived from EU countries (+ Norway, Switzerland, Lichtenstein and Islands) only.

Students from outside the area that EHIC covers are asked to have valid general health insurance.
