Prevalence of ascariasis and ancylostomiasis in families: a collaborative inquiry.
A collaborative survey was carried out to estimate the prevalence of ascariasis and ancylostomiasis in random samples of 200 families in each of 3 different communities: a city slum (CS), an industrial township (IT), a farming village community (FVC). Stool examination was done by Kato's qualitative thick smear method. Ascariasis was prevalent in all the three communities; the percentage of families with multiple members infected varied from 50 to 91 per cent; the percentage of members infected within such a family varied from 48 to 74 per cent; the infection was highly prevalent (41-78%) in all age groups excepts adults in the IT. From 8 to 11 per cent of persons with ascariasis were negative on stool examination but passed worms after medication. Ancylostomiasis was arevelent mainly in the FVC and to a less extent in the IT; the percentage of families with multiple members infected was 83 per cent in the FVC and 17 per cent in the IT; the percentage of members infected within such a family was 54 per cent in the FVC and 58 per cent in the IT. All the persons surveyed received a single 10 mg/kg dose of pyrantel pamoate (Combantrin*, Pfizer) which was well tolerated.
