WORLD HISTORY

Detailed explanation-1: -The deadly endemic diseases of yellow fever and malaria were dangerous obstacles that had already defeated French efforts to construct a Panama Canal in the 1880s. The crippling effects of these diseases, which incapacitated many workers and caused at least 20, 000 to die, led the French to abandon their goal in 1889.

Detailed explanation-2: -Over 22, 000 workers died during the French effort to build the Canal, many of them from malaria and yellow fever. The symptoms of yellow fever were terrifying: fever, headaches, back pain, extreme thirst, and black vomit from internal bleeding.

Detailed explanation-3: -Malaria continued to be a challenge throughout the entire construction program. The Panama Canal was the construction miracle of the beginning of the 20th century. It also was a great demonstration of malaria control based on an integrated mosquito control program enforced by the military. Malaria was not eliminated.

Detailed explanation-4: -Six thousand men worked in the cut, drilling holes and putting in 60, 000, 000 pounds of dynamite to break up the rock. The canal was originally a French project, and Panama was originally part of Colombia. Construction began on January 1, 1882.
