CONTROL OF MALARIA IN PANAMA WITH DRUGS 
275 
little affected by atabrine, were of course 
present in many cases. 
During the fourth year (Sept. 1933-Aug. 
1934) tablets of quinine sulphate 15 grains 
(0.972 gm) a day for 5 days were given to 
positives in New San Juan, followed 2 days 
later by plasmochin simplex 0.01 gm twice 
a day over a succeeding period of 5 days. 
The populations of Santa Rosa, Guaya- 
balito, Gatuncillo and Las Guacas were 
treated with atabrine 0.1 gm 3 times a day 
for 5 days, followed 2 days later by 5 days’ 
course of plasmochin simplex 0.01 gm twice 
a day. 
These treatment methods were continued 
in the towns named up to and including 
August 1940. The town of Agua Clara was 
added to the atabrine-plasmochin treated 
villages in February 1937. 
During the fourth year (Sept. 1933- 
Aug. 1934) a definite policy of using non¬ 
medical personnel for the administration of 
the drugs was established. Six native girls 
who were residents of their respective vil¬ 
lages were selected by the river supervisor 
(an intelligent native man), after consul¬ 
tation with the people of each village. 
These “nurses” were under the direction 
and inspection of a medical member of our 
staff, and thus soon succeeded in obtaining 
the necessary cooperation and administered 
the drugs in a fairly satisfactory manner. 
Weekly inspection trips to the villages by 
the medical staff made it possible to ex¬ 
amine and treat cases of clinical malaria 
that developed between the monthly blood- 
film surveys. 
Presentation of Data 
For the period from Sept. 1930—Sept. 
1940 the monthly and annual malarial 
parasite rates, the annual rainfall, inci¬ 
dence of malaria by age-groups, incidence 
of species of parasite, numbers of crescent- 
carriers and heavy infections, the incidence 
of malaria in infants, records of anophe- 
line collections and dissections, and the 
relation of all these to the results of treat¬ 
ment can be more easily and briefly pre¬ 
sented in tables. 
Table I shows that the malarial parasite 
rate, as determined by the monthly blood- 
film examinations, bears no direct relation 
to the seasonal rainfall, because anopheles
