Haughwout: Endemic Malaria

while seemingly in perfect health, show enlarged spleens. Cases 

 of this character may never enter the hospital at all, or they 

 .may enter to receive treatment for some other ailment con- 

 tingent upon chronic malaria, although not so recorded on the 

 hospital returns. 



Gill goes on to state that the problem of the prevention of 

 malaria in war resolves itself largely into the prevention of 

 malaria, in cantonments at the very least, in times of peace — 

 this in order that the army may confidently take the field free of 

 autogenous infection, especially if conditions there be favorable 

 to the spread of malarial infection. 



Gill has shown the conditions met in India by the recruiting 

 staff. The sequel at the front is shown by Woodcock. (36) 

 I quote from the latter author (p. 300) : 



Until July there was scarcely any malaria, but during that month it 

 began to increase. The worst months were September and October. 

 Parasites were found in forty-three per cent of the cases, and especially 

 among the Indians; quite five or six per cent in addition were obviously 

 malarial bloods, although no parasites could be found. The findings are 

 summarized in Table IV.

Among the British, benign tertian was twice as frequent as malignant 

 tertian (pernicious) , but among the Indians and Egyptian Labour Corps 

 the malignant form was by far the most common. The rarity of quartan 

 cases was noteworthy, only two being met with, both occurring in Indians. 

 I was struck by the scantiness of the parasites in quite a number of the 

 benign tertian cases among the British. Probably insufficient prophylactic 

 dosage of quinine was responsible, checking but not completely inhibiting 

 the development of the parasites. 



In all the British malignant cases, the parasites (in the ring-form) 

 were frequent or numerous, whereas the contrary was often the case 

 among the Indians. On two or three occasions, malignant parasites 

 very bacilliform in character were seen, but a few typical rings could 

 always be found by searching. Crescents were never found in the British 

 cases, as nearly all of these were new infections. [The italics are mine,
