Which disease affected Panama Canal builders and spurred the development of cures and prevention methods?

• A. Malaria
• B. Yellow fever
• C. Smallpox
• D. Cholera

Answer: (B)

Understanding how a disease spreads can change how a whole project is protected and carried out. Yellow fever caused severe sickness among Panama Canal workers, so the focus shifted from just treating sick laborers to stopping transmission in the camps. It’s spread by mosquitoes, so once researchers showed that, the response targeted the mosquitoes themselves. Efforts included removing standing water, improving sanitation around work sites, screening huts to keep mosquitoes out, and using larvicides. These measures dramatically reduced new infections and kept workers healthy enough to continue building the canal. The broader impact stretched beyond the canal, demonstrating why once a disease’s transmission is known, preventive strategies can unlock progress on large-scale endeavors. While malaria was another serious threat, the decisive shift in tackling yellow fever—identifying the vector and applying targeted prevention—stands out as the turning point that spurred cures and prevention methods in that era.
