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.

Will Brazilian antigambiae measures succeed in Africa? As time goes by it will almost certainly be found that an increasing number of areas can be cleaned of gambiae and be freed of gambiae-transmitted malaria. In Africa, where the species is already widely disseminated, it would seem logical to attempt eradication by beginning in the center of the area to be cleaned and working always outward. It has been demonstrated in Brazil that species eradication of Aedes aegypti and Anopheles gambiae is feasible.

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

It’s not that easy living with malaria. The reality of the high annual death toll should make that very obvious.

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.

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