What disease spread quickly among the workers of the Panama Canal?

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

Answer: (B)

Disease transmission by mosquitoes in a tropical work environment explains why yellow fever spread quickly among Panama Canal workers. Yellow fever is carried by Aedes mosquitoes, and in the canal zone these bites swept through camps rapidly, causing sudden, severe illness and disruption to construction. The turning point here is that public health measures targeting mosquitoes—draining standing water, screening buildings, and spraying—dramatically reduced cases and allowed work to proceed. While malaria also affected workers, the rapid, outbreak-style impact and the subsequent vector-control Revolution are most closely associated with yellow fever in this historical setting. Cholera isn’t transmitted by mosquitoes, and dengue, though mosquito-borne, didn’t define the canal-era health crises in the same way.
