A survey of 428 households in a shanty town in Coatzacoalcos, Mexico, revealed high

heavy infections through the town. Within each age class, those individuals with egg counts
in the upper 20% of the range for that age were classified as “heavily infected”. When the
data were stratified by household size, it was found that the distribution of “heavily-infected” …
