Having a satisfactory health status is an absolute must to enjoy a rewarding life; therefore achieving an universal health care coverage is an essential requisite to reach not only the SDG 3 related to Health and Wellness for all by 2030, but to achieve the 17 SGDs, since it is a reality that without health there is neither human nor economic development. In developed countries, Health Care Systems are under huge stress due to the demographic changes, with the increase in life expectancy, and the lack of equity which is becoming an everincreasing problem. In the developing countries, the situation is rather challenging due to the chronic shortness of human and material resources and the lack of infrastructures.
