Epizootiologic studies were carried out from the introduction of the transmissive gastroenteritis on the Enterprise up to the end of 1984. Clinical observations and morphologic survey were conducted on the infected animal farms. The diagnosis was based on both virologic and serologic investigations with routinely employed methods. The basic reason for the occurrence and spread of transmissive gastroenteritis on the Enterprise were shown to be omissions in the system of prevention measures with regard to infectious diseases, i. e., the functioning of farms as open units and the intense connections between them. The basic way of spreading the infection was shown to be the removal of animals from healthy to affected farms. The part played by other ways of infection transmission proved negligible, and the strict adherence to veterinary and sanitary requirements of protection guaranteed to a high extent the prevention of transmissive gastroenteritis on swine-breeding complexes and farms. It was also found that the disease assumed a stationary character on the infected farms, with periodic enzootic outbreaks in some of them associated with the nonobservance of feeding and raising technologies.

Twelve cases of gastroenteritis caused by Escherichia coli 0142K86H6 are described. Ten of these cases were clearly involved in an outbreak of cross infection. The other two cases yielded interesting information on infection with E. coli. 0142. Five cases, two being fatal, required repeated intravenous infusion, and one further infant required parenteral replacement therapy on a single occasion only. Cross infection occurred at the primary site-a ward partitioned into cubicles-despite full barrier nursing techniques. Infection spread also to two other wards, and resulted from transfer of latently infected cases. Illness in several infants was protracted and debilitating because of the relapsing nature of the infection. The pathology of the two fatalities is reported briefly.

An epidemiological survey was undertaken to establish the importance of rotavirus as a cause of admission of children to hospital in Buenos Aires, Argentina. Between August 1978 and January 1980 rotavirus infection was detected in 62 (34%) of 180 infants and children admitted to hospital with acute gastro-enteritis. In identification of the virus, electron microscopy (EM) was found to be as sensitive as counterimmunoelectrophoresis (CIE). There was agreement between EM and CIE diagnosis in 90.5% cases. Adenovirus and coronavirus were detected by electron microscopy less often. A serological response to rotavirus was revealed by complement fixation test in 38 (72%) of 53 infected patients. Rotaviruses were detected throughout the year, but peak incidence occurred during the cooler months, May to August. Infection was commoner among children under six months of age. Diarrhoea was generally mild in these children and respiratory illness showed no significant association with rotavirus gastroenteritis. These results indicate that rotaviruses may be a major cause of infantile acute gastroenteritis in Buenos Aires, Argentina especially during the winter.

During a three-year period, 336029 children were accorded ambulatory care and 40 492 children were admitted to the Institute of Child Health, Kabul, for in-patient treatment. Sixty-three per cent were boys. Three-quarters (75.3%) were under five years of age and provided 81.7% of the overall mortality. Children with acute gastroenteritis and respiratory infections together accounted for 49.9% of all admissions and 34.5% of all deaths. Malnutrition of varying degrees was a core problem and was seen in 67% of hospitalized children. The infectious diseases as a single group accounted for 70.7% of the morbidity and 71.9% of the mortality. Septicaemia and infections of the central nervous system were associated with the highest case fatality rates, especially among newborn babies. Six-target diseases and accidents accounted respectively for 10.4 and 9.7% of all deaths. Sixty-three per cent of children died within 24 hours of admission and the majority of deaths occurred after regular hospital working hours. In order to safeguard the well being of children in Afghanistan, and to reduce their morbidity and mortality, it will be mandatory to ensure effective delivery of primary health care, improve nutritional standards, provide safe drinking water, immunize the vulnerable population, make free elementary education universal and improve the lot of women and future mothers.

An outbreak of Norwalk agent gastroenteritis occurred in a chronic-care hospital in Tennessee in April 1981. Fifty-five per cent of the elderly psychiatric patients and 61 per cent of the nursing employees on one floor became ill. Infection was most likely to have spread from patient-to-patient by nursing employees. Certain chronic medications seemed to protect patients from symptomatic infection. Anticholinergic drugs appeared to mask the symptoms of this disease; psyllium ('Metamucil') may have prevented infection in some patients. We suggest that prospective studies be undertaken to confirm the possible value of psyllium in averting infection with Norwalk agent.

Rotavirus infection in black infants contrasts markedly with that of white infants in being much less common and showing no seasonal variation. In this multicentre study in Johannesburg, the aetiology of winter infantile gastroenteritis in black, coloured, and white infants was investigated. Stools were examined by electron microscopy and also by enzyme-immunoassay to detect subparticular antigen which may be missed by electron microscopy in patients presenting late in the course of the illness. Stools were also examined bacteriologically by conventional techniques. Rotavirus was the most common pathogen in all three population groups with bacteria playing a relatively minor role. Striking differences were observed in the rotavirus rates between the three groups. Infection in the whites was five times more common than in the blacks (60% versus 12%) with the coloureds intermediate at 40%. The hypothesis was put forward that the relative protection of the black population may be due to a greater degree of colonization of neonates, thus inducing protection against symptomatic infection at the target age of 6 to 24 months. This may well have important implications in immunoprophylaxis. The reason for the lack of seasonal variation in the black population is still unclear.

Fastidious enteric adenovirus have recently been recognized as an important cause of acute gastroenteritis in young children. Their inability to grow in vitro has hampered classification by conventional methods. With modern immunological and chemical techniques the enteric adenoviruses have been shown to be distinct from the 39 established human adenovirus serotypes. In a prospective study of the viral, bacterial and parasitic aetiology of acute gastroenteritis 410 children and 205 age-matched controls were studied. An enteropathogenic agent was detected in 67% of the diarrhoeic patients and 57% were of viral origin. Rotavirus was the major agent found in 43% of the patients whereas adenovirus was found in 13%. Of the 50 adenovirus specimens, so far fully characterized by electron microscopy, ELISA-assays, DNA-restriction analysis and isolation studies 70% were identified as enteric adenoviruses. Two serotypes, adeno 40 and 41, were detected representing the new subgroups F and G. Twelve of 17 paired serum specimens, from children with enteric adenovirus showed a significant rise in hemagglutination inhibition titers. Infection with enteric adenoviruses showed 2 small seasonal peaks in summer and late winter. Infection occurred early in life, 85% of the children aged less than 3 years. Diarrhoea was the main symptom with an average duration of 9 days. Adenovirus type 41 seemed to cause diarrhoea of longer duration. Fever and vomiting was mild with a mean of 2 days. Respiratory symptoms occurred in 20% of the cases. The incubation period could be estimated as 7 days. Virus was excreted for 10-14 days.

In a prospective survey carried out over 12 months 447 children aged under 2 years were admitted to the Manchester Regional Infectious Diseases Unit for treatment of gastroenteritis. Comparison of the children with those in a survey 15 years previously in the same unit showed that the illness was milder than in the earlier series, with no deaths and with lower incidences of hypernatraemia (1%), uraemia (8%), and dehydration (14%). These improved findings occurred despite several deficiencies of care in the prehospital phase of the illness, particularly poor compliance with the widely recommended guidelines for fluid and dietary management in infantile gastroenteritis.

Over the decade from 1971 to 1980, there was a decline in Western Australia in the number of Aboriginal infants and children admitted to hospital with infections. The most marked change occurred in admissions for gastroenteritis and other infections in the Kimberley region in the far north of the State. Despite this decline, there is still a very wide gap between the rate of admission to hospital for infectious diseases of Aboriginal and that of non-Aboriginal infants and children. The decline reported here is considered to reflect improvements in health status caused by several interrelating factors, including improvement in the general standard of living, housing and hygiene, and the provision of comprehensive, community-based health programmes. Environmental contamination is still a major factor causing ill health in Australian Aboriginal communities.

Nausea and vomiting occur commonly with gastroenteritis caused by parvovirus-like agents. Infection results in histologic injury to the small bowel mucosa, but the gastric mucosa remains unaffected. We have studied gastric emptying of liquids serially in 10 volunteers before and after ingestion of the parvovirus-like agents, Norwalk and Hawaii viruses. The five subjects who developed illness all showed marked delays in gastric emptying, while the five well subjects had no alteration of emptying. Five addition volunteers who developed Norwalk virus gastroenteritis underwent serial studies of gastric secretion of hydrochloric acid, pepsin, and intrinsic factor. No change was detected in either basal or betazole-stimulated secretion of these three substances during the course of illness. The nausea and vomiting accompanying this type of viral gastroenteritis may result from abnormal gastric motor function.
