Malaria control operations. Trees being felled in Panama circa 1910 as part of malaria control operations. After the trees are cleared,a ditch will be dug to drain the standing water,which is acting as a breeding ground for mosquitoes. Control of mosquitoes helps to prevent or reduce the incidence of malaria,as well as several other mosquito-borne diseases. Photographed in New Market Creek Swamp,Panama,during the period of the construction of the Panama Canal (1904 to 1914). Reducing the levels of mosquito-borne diseases like malaria and yellow fever in the workforce was critical to the building of the Panama Canal | |
