Cuba is commemorating the 58th anniversary of the official beginning of medical cooperation with other territories on Sunday, a time during which it has extended its medical services to 1.9 billion people, nearly one-third of the world's population.
Although Cuba's solidarity dates back to 1960, when a medical brigade went to Chile to help the victims of an earthquake in the southern city of Valdivia, it was not until 1963 that Havana sent professionals on a permanent basis.
