F. Summary

  • a.  Four different methods of malaria control were tested under field conditions in four separate towns in a tropical country where original incidence of malaria, as measured by splenic and blood findings, was highly comparable.
  • b.  The incidence of malaria in all of the towns was severe to hyperendemic.
  • c.  Meteorological factors were highly comparable in the towns, if they cannot be classified as identical. All towns were situated on the coastline within fifteen miles of one another.
  • d.  Three surveys were performed in the towns over the period of nine months before any control was instituted, to serve, together with a comparison town, as a baseline from which to measure results.
  • e.  All control was begun at the same time following the third survey of December 1945.
  • f.  Subsequent surveys following the initiation of control procedures, were performed at the identical time of the year as those performed during the first nine months of observation.
