No data. 











There was no mortality for the undetermined fevers shown in the Table III 

 except in 1900 when it was 0.01 per 1,000 in the Philippines and 0.05 per 1,000 

 in the United States. ' ' 



On studying these tables it will be observed that for the ten-year period 

 the typhoid admission rate per 1,000 has been higher in the Philippines 

 than in the United States, 6.28 as compared with 6.10. The death rate 

 from typhoid has been three times as high in the Philippines, 1.06 per 

 -1,000 as compared with 0.36. During the years 1907 and 1908, when the 

 sanitary conditions and the ^service conditions in the Philippines closely 

 approximated those at home, the typhoid admission rate has not materially 

 differed in the two countries while in 1909 it was twice as high in the 

 Philippines as in tlie United States. The admissions for 1910 have be^n 

 38, making an admission rate of approximately 3.1 per 1,000 which 

 exceeds the home rate for 1908 and 1909. 



In considering the comparative admission rates for typhoid in the Islands 

 and at home, it is important to bear in mind that in the United States the wat6r 

 supplies of many towns and posts are not above suspicion, yet little care is 

 generally exercised by soldiers to avoid drinking these doubtful waters. In the 

 Philippines distilled water, of unquestioned purity is everywhere furnished fpr 

 soldiers and the fear of dysentery and cholera, together with the stringent orders 

 on the subject, make the drinking of this water veiy general. If the same 

 carelessness in drinking which we see everywhere at home were practiced here, 

 we believe that the typhoid rate would be very much higher than it is at present. 



A consideration of the above remarks points very strongly to a wide 

 spread and easily accessible source of typhoid infection in these Islands.
