THE INTESTINAL WORMS OF 385 FILIPINO WOMEN 

 AND CHILDREN IN MANILA.'

Last year a paper was presented before this association giving tlie 

 results of the examination of over 4,000 adult, male, • Filipinos for the 

 prevalence of animal parasites.* 



The differences which have been reported by numerous authors between 

 the frequency of infection with the various species of parasitic worms in 

 males and in females and in adults and in children were used at that time 

 to make a general forecast of what frequency of infection might be 

 expected in Filipino women and children. However, it remained to 

 definitely inform ourselves concerning the parasites of women and 

 children by actual examination. The results here reported are the first 

 step in that endeavor and are based upon the examination of 385 women 

 and children in Manila. The examinations were made at Bilibid Prison, 

 Hospicio de San Jose, St. Paul's Hospital, and tlie School for Deaf and 

 Dumb Children of the Bureau of Education, and to these institutions we 

 would acknowledge our indebtedness for the facilities provided. 



Of the total 385 persons examined, 342 or 89 per cent were infected 

 with intestinal worms as against 84 per cent of the male prisoners at 

 Bilibid. The total number of infections found in the 385 women and 

 children was 533, or 138.7 infections to each 100 persons examined, 

 against 142 infections with intestinal worms in each 100 men. 



Of the 385 persons examined, 227 were women — and of these alone

* Among the 385 women and children examined, amoeba were found 37 times 

 (10.8 per cent) and other intestinal protozoa 24 times (7.0 per cent), lliese 

 figures are excluded from our statistics since the examinations were frequently 

 made vmder conditions unfavorable for diagnosing these infections, most often 

 owing to the lapse of time after the specimen was passed before the examination 

 could be made.
