A STATISTICAL STUDY OF UNCINARIASIS AMONG WHITE 

 MEN IN THE PHILIPPINES. 1 



By Weston P. Chambeklain. 1 



The subject of hookworm disease at the present time is so much before 

 the public that it may be of interest to consider in detail one feature of 

 the situation, namely, the occurrence of the disease among adult American 

 males in these Islands. Of all the infections which commonly are included 

 in books on tropical medicine there are few, if any, which have such a wide 

 distribution geographically, and especially such a range in latitude as 

 uncinariasis. It is found in many regions that can lay no claim to being 

 tropical, or even subtropical. Therefore, when studying the origin of the 

 disease among Americans in the Philippines, it is necessary to consider 

 two widely separated sources of infection : First, the Philippine Islands, 

 and, second, certain parts of the United States where the disease is 

 endemic. 



OPPORTUNITIES FOE INFECTION IN THE PHILIPPINES. 



When a white man in the Philippines is found to be harboring hook- 

 worms one is apt to assume that he became infected in the Islands, and 

 a study of helminthiasis among the natives shows that opportunity for 

 soil contamination is not lacking. 



The first extensive work performed along this line was the examination of 



1 Kead at the first biennial meeting of the Far Eastern Association of Tropical 

 Medicine, held in Manila, P. I., March 7, 1910.

 for the Study of Tropical Diseases as they occur in the Philippine Islands.
