“…The rate of HCGI (Table 14) was similar to that observed during our previous study (Paym ent et al 1991a(Paym ent et al ,b, 1993. These results are also comparable to data reported in the early 1950s during the Cleveland studies (Hodges et al 1956) and in the 1980' s during the Tecumseh studies (M onto et al 1980, M onto et al 1983). W hile the annual average rate of gastrointestinal illnesses is relatively constant from year to year, weekly or monthly rates are unpredictable (Rothbart 1995).…”

The objective of this study was to assess if drinking water meeting currently accepted microbiological standards is the source of gastrointestinal illnesses and to attempt to identify the source(s) of these illnesses. A randomized prospective study was conducted over a period of 16 months (September 1993 ±December 1994 in a middle class suburban community served by a single water filtration plant. A representative sample of 1400 families were selected and randomly allocated in four groups of 350, to the following regimens: (1) tap water; (2) tap water from a continuously purged tap; (3) bottled plant water; (4) purified bottled water (tap water treated by reverse osmosis or spring water). The water treatment plant produced wather that met or exceeded current North American regulations for drinking water quality. The distribution system was found to be in compliance for both coliforms and chlorine. Using the purified water group as the baseline, the excess of gastrointestinal illness associated with tap water was 14% in the tap group and 19% in the tap-valve group. Children 2 ±5 years old were the most affected with an excess of 17% in the tap group and 40% in the tap-valve group. Mottled plant water was not the source of any increase in the incidence of gastrointestinal illnesses, even if it contained very high levels of heterotrophic bacteria after two weeks. The data collected suggest that 14 ±40% of the gastrointestinal illnesses are attributable to tap water meeting current standards and that the water distribution system appears to be partly responsible for these illnesses.

“…It was much lower (by between ten-and twenty-fold) than the incidence of enteritis in the community recorded in volunteer studies (Hodges et al 1956;Monto & Koopman, 1980). It is likely, therefore, that only a small proportion of these illnesses caused the patient to consult their doctor.…”

SUMMARYThe incidence and clinical features of campylobacter enteritis were studied in a defined general practice population over a period of three years. Specimens of faeces were cultured from a representative sample of patients suffering from acute enteritis. Of 168 patients submitting a specimen to the laboratory 34 (20-2 %) were positive for thermophilic Campylobacter species. The projected campylobacter infection rate varied from 5-4 % per annum in infancy to 0 3 % per annum in the 5-to 14-year-olds with a mean of I -I % per annum for the whole study population.During the same period campylobacters were isolated from 484 (14-9 %) of 3250 patients suffering from acute enteritis whose general practitioners had sent faecal specimens to the laboratory, confirming the importance of this organism in the aetiology of acute enteritis in the community.

“…7,8 Few studies have investigated the incidence of gastrointestinal disease at the community level, and most of these studies have been conducted in North America. These studies include the Cleveland study, 4,9 the Tecumseh study, 10,11 and the Virus Watch Program. 12 Reported gastrointestinal illness rates were in the range of 0.5 to 2 episodes per year per person, varying from 5 to 100 episodes per 1000 persons per week, according to seasons and age.…”
