title: Diarrhea and school toilet hygiene in Cali, Colombia.
abstract: In a 4-week period in early 1976 in a poor, working class area of Cali, Colombia, the prevalences of diarrhea, vomiting, common cold, and head lice in schoolchildren were measured in relation to classroom size and to the condition of the school toilets. The study found that unhygienic toilet conditions were related to diarrhea, and it was estimated that if all schools could reach the modest level of hygiene of the two schools with the relatively best facilities, diarrhea would be reduced by 44% and vomiting by 34%. Toilet hygiene was found to be unrelated to colds or head lice, which have similar social class distributions to diarrhea and vomiting. Crowding was found to be related to a small percentage of the prevalences of vomiting, head lice and colds.
