Inventions of the electric light, steam engine and railroads helped in the growth of U.S's Industrial boom in the 1900s during the Industrial Revolution bringing a rise for more labor. The invention of the railroad system, for example, made it possible to transport goods over long distances or a short period resulting in the creation of more jobs in various industries (Mantoux, 2013). These inventions of the industrial revolution affected workers, i.e., workers were paid poorly, child labor was introduced, cities were crowded and filled with diseases (Nelson, 1996).

To combat the threat of tropical diseases such as malaria and yellow fever, the United States decided to use new measures to eradicate the disease before the construction of the Panama Canal. Under the leadership of Colonel William Crawford Gorgas, many changes were made. When it was discovered that mosquitoes were the source of the disease, Gorgas who was appointed as the head of hospital and sanitation, he made sure that containers with stagnant water were removed because mosquitoes lay their eggs there. He also built domestic water systems to eliminate the need to collect rain water. Prophylactic Quinine was supplied to the people in the area and fumigation and oiling of streams were launched. Those who were sick were quarantined and workers would sleep in screened structures so that mosquitoes would not be able to bite them. These programs resulted in the successful elimination of tropical diseases in the area and the health of workers improved.
