The national health system includes the Ministry of Health, which provides leadership for the sector; the Costa Rican Social Security System (CCSS), which delivers care in the event of disease and maternity; the National Insurance Institute (INS), which offers protection against work-related and transportation accidents; and the Costa Rican Institute of Water and Sewerage Systems (AyA), which regulates the supply of water for human consumption and the management of wastewater.
The public institutions receive a budgetary allocation from the State treasury, and the CCSS is funded with contributions from employers, workers and the State.
