A. Fewer workers got sick from malaria and yellow fever.

New scientific knowledge helps the building of the Panama canal because there was a reduction in workers who are becoming sick of yellow fever and malaria. The Chief Medical Officer Colonel Gorgas, was among the first who have learned about the revelations associating with malaria and mosquitoes. Due to those interpretations, he succeeds in abolishing the cause of the disease which could able to decrease the number of workers getting infected.
