5 Quotes by Fred Lowe Soper

It is much easier to evaluate perfect rather than partial results.

It was not feasible to lose time in making careful surveys or extensive preliminary studies of possible control methods; learn how to get rid of Anopheles gambiae by actually getting rid of Anopheles gambiae.

Preferring steady progress, slow and imperfect, is a good philosophy for the defeated.

The use of vaccine in the control of yellow fever should occupy more or less the same place that typhoid fever vaccine has in the control of typhoid fever. No sanitary authority would desire to substitute typhoid vaccine for the supply of pure water and food, so we must not accept the yellow fever vaccine as a substitute for the elimination of Aedes aegypti. The vaccine provides individual protection for the person who cannot be protected by more general measures.

Recognizing its importance, Aedes aegypti should be studied as a long-term national, regional, and world problem rather than as a temporary local threat to the communities suffering at any given moment from yellow fever, dengue or other aegypti-borne disease. No one can foresee the extent of the future threat of Aedes aegypti to mankind as a vector of known virus diseases, and none can foretell what other virus diseases may yet affect regions where A. aegypti is permitted to remain.
