A case was defined as a resident of San Francisco with AIDS who was reported to the San Francisco Department of Public Health with a laboratory-confirmed, positive stool test for Cryptosporidium parvum from May 1996 through September 1998.
Cryptosporidium oocysts have an ubiquitous geographic distribution and can be detected in most surface drinking water sources [ 8 ] . The oocysts are resistant to environmental degradation [ 9 ] , survive chlorination water treatment, and are too small (4 to 6 microns) to be removed by conventional water filters [ 6 ] . Risk factors for acquiring cryptosporidiosis have been determined primarily in studies of community-wide outbreaks, and drinking water has been implicated as the source of these outbreaks [ 9 10 11 12 13 14 ] . Case-control studies in AIDS patients have also been conducted during outbreaks [ 12 15 ] , but levels of endemic risk in the United States remain uncertain, even though there is great concern for diarrheal disease associated with drinking water in this population [ 16 17 ] . Because defining the risk associated with drinking tap water is particularly important for counseling immunocompromised patients on reducing their risk of cryptosporidiosis, we conducted a case-control study among persons with AIDS in San Francisco to test the hypothesis that the pattern of tap water consumption is associated with the development of endemic cryptosporidiosis.
Because the incubation period between exposure to Cryptosporidium oocysts and symptoms is not well understood in persons with AIDS, it is possible that contact with fecal material which occurred long before the incident diagnosis might be the source of these infections.
Because symptomatic cryptosporidiosis cases represent only a small fraction of those who may be infected with Cryptosporidium , the conclusions drawn from a study such as ours may not apply to those asymptomatically infected.
Cases were recruited from those individuals identified through surveillance who had a stool test that was positive for Cryptosporidium . Cases who were reported to the CEIP from July 1999 through July 2001 were invited to participate in the case-control study and were screened for eligibility before administration of verbal consent and the questionnaire over the telephone.
