TYPHOID FEVER IN THE PHILIPPINES. 



317 



Group II; 19 cases with short ill-defined fever of less than 10 days' 

 duration; 13.1 per cent. 



Group III ; 41 cases of irregular fever of less than 10 days' duration, 

 probably representing last part of mild ambulant typhoid types; 26.6 

 per cent. 



Group IV ; 89 cases of well marked continued fever, clinically typhoid, 

 lasting more than 10 days; 56.6 per cent. 



GROUP I. CASES TERMINATING FATAXLY. 



Seven patients out of the 157 died, a mortality of 4.5 per cent. The 

 cause of death was peritonitis following perforation of the intestine in 3 

 instances, toxasmia in 3, and shock following haemorrhage in one. Bacillus 

 typhosus was obtained from the blood of 3 of these fatal cases and from 

 the gall bladder of another. 



Eogers found a mortality of 16.3 per cent among 139 cases in Calcutta 

 and reports that in the British army in India the returns show a death 

 rate of 26 to 27 per cent at the present time (1909-1910). This in- 

 dicates a more serious condition than is seen in these Islands. The range 

 in the typhoid mortality experience of the Army in the Philippines for the 

 last ten years as contrasted with that among the troops in the United 

 States is shown in Table XV :

Average ... 

















" The average mortality was obtained by dividing the total number of deaths for the 

 period under consideration by the total number of cases for the same period. 



It will be observed that the average mortality is a trifle higher for the 

 Filipino than for the American troops serving in the Philippines, 17.6 

 per cent as compared with 16.8 per cent. It is quite probable that
