PROPHYLAXIS OF MALARIA.

although the ward was not screened and anophelines were present. 
It is needless to comment upon such a situation, but it is one 
that will continue to occur, in isolated instances, until the malarial 
fevers are considered as infectious diseases and the same precautions 
taken to prevent their spread as would be taken in the case of yellow 
fever. 
In a carefully screened ward it would be unnecessary, of course, 
to further screen a malarial patient, but in an unscreened ward this 
should always be done, and, under such circumstances, it is better to 
place the patient in a room by himself, the same precautions being 
taken regarding screening, nor should he be allowed to leave the 
screened quarters until the plasmodia have either disappeared from 
his blood or been reduced to a noninfectious minimum. This will, 
of course, necessitate a microscopic examination of the patient's blood 
at daily intervals, but it is only by such an examination that we can 
adequately control the treatment of malaria and render the pro¬ 
phylaxis of the disease effective, so far as the patient is concerned. 
The screening of every individual in hospital for malarial fever is 
an absolutely necessary prophylactic measure if one desires to limit 
the spread of these infections.
