PROPHYLAXIS OF MALARIA. 
113 
The suggestions given above for the prophylaxis of malaria in 
the field, in temporary camps, and in permanent posts, do not cover 
all that may be done along this line, but may serve as a guide in the 
prevention of these infections in the military service. The aim of 
the medical officer should be to do all in his power to prevent the 
transmission of these infections, but the methods to be adopted will 
vary, of course, with special conditions, and it will often be possible 
to control the disease without resorting to all of the methods that 
have been described. However little he may be able to do in the 
way of eradicating mosquitoes, he has absolute control over patients 
in hospital, and can see that no man who has been in the hospital for 
malaria is returned to duty until he has ceased to be a source of 
danger to his companions. He can also insist upon the continuance 
of quinine until there is a reasonable surety that the infection is 
cured, and thus prevent the recurrences which furnish the majority 
of malarial cases in any hospital. 
In conclusion, it may be stated that the malarial fevers are en¬ 
tirely preventable and their presence, to any extent, in an army 
post is a reflection either upon the intelligence of the sanitary officer 
in control, or upon that of other authorities who, either by indiffer¬ 
ence to the recommendations of the sanitary officer or unwillingness 
to supply the necessary funds, have rendered the efforts at prophy¬ 
laxis futile.
