In Argentina the health system has three sectors that are: public health, social security and private. The private sector basically aims to profit. The other two aim at caring for your health. The public sector is mainly used by poor people that are unemployed. Social security sector is financed by workers and it is for workers. This last one is the friendliest and offers the widest coverage. It cannot refuse anyone based on pre existing conditions or age, and it always costs the same % based on income. Age,etc do not have an influence. You can access by becoming a registered worker or self employed enrolled into monotributo.
