According to recent news a Cuban medical program, said to be active in many countries including Africa, is providing services in some areas free of charge.
A major mission is believed to be in Venezuela where the scheme has been criticised by the u.s. who reportedly have said that it undermines democracy. The u.s. in return have been accused of trying to damage the left wing scheme.
According to Cuba’s ministry of foreign affairs, an estimated 600,000+ medical staff including doctors, nurses and technicians have been sent to 160 countries since the 1960’s.
There is a surplus of doctors in Cuba, perhaps because the emphasis is said to be on vocation.
