150 DISEASES DUE TO PROTOZOA 



Attempts have been made to procure a curative and immunizing 

 serum, but without success for man. 



It is interesting to note that the physician, Kerandal, claims as his 

 cure intravenous injections of tartar emetic given in four series of daily 

 injections of lo cm. each, the number of doses in each series being 17, 

 15, 15 and 18 respectively, or 55 in all, equal to 5-50 grm. of tartar 

 emetic. His weakness disappeared as " if by enchantment " after 

 the first course of injections. Atoxyl, of which he took 70 grm. in all, 

 did not appear to affect the course of the disease. 



PROPHYLAXIS. 



What has been said about sanitary measures for the prevention of 

 mosquito breeding need not be repeated here. 



In whatever work is undertaken the Government must co-operate. 



There should be medical inspection of all the villages on the 

 boundarv of the fly area. Natives must co-operate also, and this is 

 the most difficult task. If they do not volunteer to do so they must 

 be forced. Some suggest that the infected should be isolated and 

 treated, but this is neither practicable nor possible in the District du 

 Kwango of the Belgian Congo, where about 70 per cent, of the total 

 population is infected. To adopt such regulations would mean the 

 closing down of all important works in that district, and the natives 

 would be far worse off than before. 



Flv-free areas should be chosen or prepared, new villages built 

 and maintained, plantations prepared and maintained, all infected 

 villages to be destroyed and the inhabitants removed to the new ones, 

 the infected peoples treated drastically, and those in the last stage 

 removed to lazarets. This is a gigantic task, and is beyond the purse 

 of the Government or any private enterprise in Central Africa. It 

 should be worked as far as possible. The bush should be cleared and 

 planted for 300 metres around every village, and from the water's edge 

 for 100 metres. Then a new generation of individuals would arise, 

 free from the disease, capable of increasing their kind and developing 

 their country under guidance and control. 



Fly catching is impracticable in most districts to be of any real 

 good . 



The extermination of big game is, in my opinion, unadvisable. 

 Wherever man may go some animals will accompany him, and these 

 will become carriers as well as man. 



The legs of Europeans should always be protected with puttees or 

 leggings when passing through fly districts. 



European residences should be well away from native quarters. 



Quinine does not seem to be a prophylactic in any way.
