Disease and infant mortality increased in the 1960s immediately after the revolution, when half of Cuba's 6,000 doctors left the country. Recovery occurred by the 1980s, and the country's health care has been widely praised. The Communist government stated that universal health care was a priority of state planning and progress was made in rural areas. After the revolution, the government increased rural hospitals from one to 62. Like the rest of the Cuban economy, medical care suffered from severe material shortages following the end of Soviet subsidies in 1991, and a tightening of the U.S. embargo in 1992.
