Roosevelt visits the Panama Canal under construction, in 1906 (Source: BBC)
Teddy Roosevelt wanted to build a canal through the Isthmus of Panama, and no one was going to stop him. First, we need to remember that before the Americans began the massive engineering project, what we now know as Panama was part of Colombia. When the Colombian government did not agree to the terms desired by the Roosevelt administration, the United States supported a junta-led rebellion that otherwise would have been crushed by the Colombian military.
The United States sent gunboats to both shores and a battleship to Colón, Panama to insure success of the rebellion. The collaboration included a French engineer (and investor in the earlier French project, who stood to gain significantly when the United States compensated the French company for its rights) who immediately after the rebellion negotiated an agreement with Secretary of State John Hay on behalf of the junta. The terms included United States sovereignty over a ten-mile-wide swath of land from the Atlantic to the Pacific. This was not one of those bright, shining moments in United States history.
Once the United States took control of what would become the Panama Canal Zone, the Isthmus Canal Commission, the governing body of the zone, had to conquer the enemy that had ground the French to a halt – the yellow fever- and malaria-carrying mosquitoes.
Timing is everything. In 1880, French Army Surgeon Charles Laveran first discovered parasites in the blood of a patient suffering from malaria. In 1886, 1890, and 1897, Italian scientists made further discoveries about the specific malaria parasites. Also in 1897, British medical officer Ronald Ross demonstrated that malaria parasites could be transmitted from patients to mosquitoes and from bird to bird, and that the parasites could be developed in and spread by mosquitoes.
During the American occupation of Havana after the Spanish-American War, army surgeons developed programs that reduced mosquito breeding, thereby eradicating yellow fever and greatly reducing malaria. In 1904, Colonel W.C. Gorgas applied the lessons of Cuba in a seven-prong program to attack mosquito breeding in tropical Panama: draining pools near villages and homes; cutting brush and grass near villages and homes; using oil to kill mosquito larvae where drainage was not possible; spreading larvacide where oiling was ineffective; dispensing quinine to workers as a prophylactic measure; screening government buildings and living quarters (screening for living quarters was limited largely to quarters for white workers); killing adult mosquitoes found in houses during the daytime.
Just as in Cuba, the program largely eradicated yellow fever and dramatically reduced deaths from malaria. Hospitalizations for malaria decreased from 9.6% of employees in 1905 to 1.6% in 1909.
As I said earlier, timing is everything. Without the discoveries made in the decades preceding the United States’ success in Panama, the Americans may well have met the same fate as their French predecessors.
