Later on his journey, Guevara was especially impressed by the camaraderie among those living in a leper colony, stating, "The highest forms of human solidarity and loyalty arise among such lonely and desperate people."
Pada masa akhir perjalanannya, ia merasa sangat terkesan dengan persahabatan orang-orang di koloni lepra, dan ia berkomentar bahwa "Bentuk solidaritas dan kesetiaan manusia yang tertinggi muncul di antara orang-orang yang kesepian dan putus asa."
