The Health care system is largely financed from the Government budget and from the State Fund for Health Development which is financed from contributions for Voluntary Medical Insurance as well as some fees and co-payments. Resources from the SFHD are then used to pay compensation for insured persons, purchase essential drugs and medical equipment, finance research and social programmes, and purchase modern medical technology. Insurance coverage was about 90% in 1999. Overall budget contributions to the health sector have varied significantly since the start of the transition. Health care expenditure fell from 3.2% of GDP at the start of the transition in 1991 to 0.8% of GDP in 1994, increasing to 4.6% in 1997. The Presidential target is to increase it to 5.5% by the year 2000.
