“…1), with the highest incidence of infection consistently occurring during the summer months (June to September). Finding higher isolation rates from June to September is consistent with reports from the United States (1), Belgium (2), Britain (9), Spain (13), and Sweden (14). This seasonality was apparent for data from each laboratory separately ( Fig.…”

Isolation rates of Campylobacter spp. were analyzed for an 8-year period, 1978 through 1985. Three laboratories of the Ontario Ministry of Health examined 146,842 human feces samples for bacterial pathogens, including Campylobacterjejuni and Campylobacter coli. Campylobacter spp. were isolated from 5,580 specimens (3.8%), with monthly isolation rates ranging from 1.1 to 7.4%. The data showed a seasQnal distribution of isolations, with peaks during the summer months (June to September). Most infections were in children, adolescents, and young adults. More males were infected than females; this finding was most pronounced in the age groups under 25 years. In Northern and Central Ontario, a strikingly higher incidence was observed among farm residents than among rural nonfarm or urban residents. Of 89 farm residents, 63 had consumed raw milk (61 bovine, 2 goat) within 72 h before becoming ill.

“…Diarrhoea1 diseases continue to be a global health problem among young children in developing nations (11). Facilities and resources for the isolation and determination of causative agents of diarrhoea are essential for a developing country (1,4,27,54,55), which may contribute to a better surveillance and early recognition of diarrhoeal infections. In our study the total isolation rate of enteropathogens was 73.4% ; 53.5% were of bacterial origin and 19.9% of viral origin.…”

The causative agents of acute diarrhoea were investigated in children under the age of five years from 1985-1991 in three socio-economically different areas in Lahore, Pakistan. The aim was to determine the frequencies of the most common enteropathogens in faeces. The total isolation rate was 73.4%; two thirds (53.5%) were of bacterial and one third (19.9%) of viral origin. ETEC-LT (23.4%), Rota virus (19.9%), EPEC (15%) and Campylobacter (12%) were the single most frequent pathogens in all age groups and areas of living. The positivity of Campylobacter increased from 1.6% to 12% after the change of isolation technique. Shigella was isolated significantly (p > 0.001) more in children over than under one year of age. The incidence of bacterial infections was high during all seasons, while in certain years Rota virus was relatively low in the summer compared to the cooler months. The prevalence of ETEC-LT diarrhoea was higher in the periurban slum as compared to the village and the urban slum. The study is the first of its kind in Pakistan, and the results are similar to other comparable studies. It is thus possible to establish a well functioning and reliable microbiological laboratory in developing countries in a setting with restricted trained personnel and material resources.

“…Before a decision is made on the introduction of mass vaccina-tion for rotavirus in Spain, information on the epidemiology and current disease burden is needed. Studies on the cause of gastroenteritis in different hospital populations in Spanish cities showed an incidence of rotavirus between 10% and 26% in populations with a variable age distribution (6)(7)(8)(9)(10). But national estimates and specific information about the incidence of hospitalization for rotavirus gastroenteritis in the age group with the highest incidence of infection are limited.…”

The epidemiology of rotavirus infection in Spain was investigated using information from existing surveillance systems. Peports from laboratories and data on hospital admissions were used to estimate the number of hospital admissions due to rotavirus infection. Between January 1989 and December 1995 there were 8265 reports of rotavirus identificatión in the Sistema de Información Microbiológica, a voluntary national laboratory surveillance system. Where age was reported, 89.2% were in children under 5 y old. This represents 21.8% of all pathogens identified in faecal specimens in children of this age group. Between January and December 1994 there were 5639 admissions coded as “infectious intestinal disease” and 8225 as “non‐infective gastroenteritis” in children under 5 y of age in the Conjunto Minimo Básico de Datos, an obligatory hospital admissions surveillance system which covers 83% of publis hospitals. Using regression analysis of admission data and laboratory reports it was estimated that rotavirus infection accounted for 3159 (25.3%) of the hospital admissions. We estimate that 4239 admissions attributable to rotavirus occurred in children under 5 y of age in Spain in 1994, a rate of 2.5/1000 population in this age group. These estimates are lower than those published for other countries, where the burden of disease is considered high enough to warrant a national vaccination programme. A costeffectivenness study with Spanish information is essential before embarking on a national vaccination programme. □Rotavirus, surveillance, vaccination
