El doctor Ernesto Guevara antes de ser el “Che Guevara”. Su trabajo en el Hospital General de México

Thousands of articles have been written about Ernesto Guevara, identified as Che Guevara. However, the work of this character as a doctor has only been recognized on a few occasions. Therefore, we consider it of interest to present his research work at the General Hospital of Mexico, an institution in which he tried to obtain a scholarship, which led him to work in the newly formed Allergy Service, founded by Dr. Mario Salazar Mallen at the beginning of The 1950s.
