Health services, safe drinking water and better nutrition have led to a 66-year life-span and lower morbidity during this life span. One of the constraints in education and health was the lack of qualified people. In 1976, King Jigme Singye commanded the establishment of the Royal Institute of Health Sciences (RIHS) and the first batch of Health Assistants and Basic Health Workers passed out in 1986. There were 56 health establishments in 1974; by 2006 there were 715 resulting in 90% free primary health coverage. In 1985, there was nearly 50% health coverage. Infant mortality has fallen from 142 in 1985, to 60 in 2006. This was mainly due to the success of universal child immunisation and the supply of safe drinking water. There were 150 water supply schemes in 1985; this increased to 3,852 by 2006, giving 78% coverage of safe drinking water. Maternal mortality rate dropped from 7.7% in 1985 to 2.6% in 2006.
