During old age, this is reflected in levels of health insurance coverage and access to health care. Coverage rates increase in proportion with age (88.1% for those aged over 80 and 63.1% for those aged 60 to 64). In Brazil, 70% of older persons are covered by the public system. In Paraguay, over 83% of older persons are calculated to have no form of medical insurance and, in the event of illness, either have to foot the bill or go without treatment (OISS, 2007).
