Which disease was prevalent among Panama Canal workers and spurred health measures?

• A. Cholera
• B. Dengue fever
• C. Yellow fever
• D. Influenza

Answer: (C)

The main idea here is how understanding how a disease spreads changes how you respond in a big work project. Yellow fever caused severe illness and many deaths among Panama Canal workers, so health officials took urgent steps to control it. This disease is spread by the Aedes aegypti mosquito, so simply cleaning up the area wasn’t enough. To break the transmission, efforts focused on mosquito control: draining and eliminating standing water where mosquitoes breed, eliminating other breeding sites, screening living quarters, covering water containers, and using insecticides around camps. These targeted actions reduced yellow fever cases and made the canal construction safer and more feasible. The episode helped illustrate why identifying how a disease spreads is crucial for designing effective public health interventions.
