Table II shows that the percentage of infected persons varies 

 from 65 to 67 and that of Trichuris from 39 to 44. Hookworm 

 and Ascaris infections vary greatly. In Cebu city, hookworm in^ 

 fection is 12 per cent less than in the towns of Cebu Province, 

 while it is 5 per cent more than that of Ascaris. If we believe 

 that the sanitary condition of the city of Cebu is better than 

 that of other towns of Cebu Province, we can deduce that hook- 

 worm infection is greatly influenced and lessened by improve- 

 ment of sanitation and Ascaris infection is altered only slightly, 

 if at all. The individual infections of Trichuris, hookworm, 

 and Ascaris in Cebu Province and outside of Cebu vary only 

 from 2 to 3 per cent. 



DISTRIBUTION BY SEX 



Out of 1,603 patients examined, 354 were women.. 

 lowing gives their corresponding infections.

Females 













The females showed about 4 per cent more infections than the 

 males. Infections with Trichuris and Ascaris were more numer- 

 ous in the females ; infections with hookworm were more numer- 

 ous in the males. A greater percentage of hookworm infection 

 in men than in women is to be expected for the reason that
