Prospective cohort study.
An urban slum in Fortaleza, Brazil.
Thirty-one households with a child less than 3 years of age (index case) who was positive for Cryptosporidium parvum using acid-fast and auramine-stained stool smears.
Three stool samples (at 0, 2, and 6 weeks after identification of the index case) and two serum samples (0 and 6 weeks) were collected from each family member in households with an index case of Cryptosporidium infection.
Forty-five percent of index cases of Cryptosporidium infection were associated with persistent (>14 days) diarrhea.
