“…The overall incidence of diarrhoea in the total study population was 0-9 cases per person-year and the peak incidence of diarrhoea in children aged <2 years was 2-1 cases per person-year [13]. The incidence of EAV-associated diarrhoea in the overall population was 2-9 cases per 100 person-years.…”

“…In the same population we have shown that 10-5 % of diarrhoea cases were associated with rotavirus in children <2 years old [13]. However in 85 % of the cases the aetiology remained unknown and probably enteric parasites and enteropathogenic bacteria have a relevant role.…”

“…In the 180 cases of diarrhoea studied, rotavirus was detected in 8 cases (4-3 %) and EAV in 6 cases (3-3 %). Nevertheless a peak of rotavirus-related diarrhoea (10-5 %) occurred during the first year of life, at an incidence of 25 episodes per 100 person-years [13]. Coinfections with the two viruses were not observed.…”

“…Between 1 May 1984, and 31 May 1986, stool specimens from a total of 766 asymptomatic individuals and 180 cases of diarrhoea were collected from the studied individuals. Our laboratory had previously studied the epidemiology of rotavirus infection under natural conditions in this population [13].…”

“…We organized a 2-year prospective study to establish the frequency of different common causes of viral infantile gastroenteritis in a normal population and some results on rotavirus have been reported [13]. As part of the study of EAV, we have included a group of children with community-acquired diarrhoea that required medical care.…”

Epidemiology of enteric adenovirus infection in prospectively monitored Argentine families

et al. 1992

SUMMARYTo examine the role of enteric adenoviruses (EAV) in an urban area of Buenos Aires (Argentina), we prospectively studied faecal samples from 49 families of newborns. These were monitored weekly for diarrhoea for 2 years.A total of 180 samples from cases of diarrhoea and 766 samples obtained during diarrhoea-free periods were studied by dot-blot hybridization with an EAV-specific DNA probe. EAV were found in 6/180 (33 %) cases of diarrhoea and 6/766 (0-8 %) asymptomatic samples (P < 0015). Incidence of EAV was 3*9 cases per 100 person-years in children < 60 months old. EAV-related diarrhoeas were slight and of short duration. In addition, 129 faeces from hospital out-patients, 1-30 months old, were also studied. EAV' was identified in 7/129 cases (54 %). These cases were 9.5 + 35 months old and the diarrhoea was mild or severe, of 3 + 15 days of duration.We suggest that EAV are low-risk causes of diarrhoea under natural conditions, although a few children may develop more severe diarrhoea. The diagnosis of EAV needs to be considered in these patients. INTRODIUCTIONAt present, 47 adenovirus (AV) serotypes have been identified. Group F comprises types 40 and 41; the enteric adenovirus (EAV). These have been implicated as the second most common cause of viral gastroenteritis in infants and young children, after rotavirus [1][2][3]. Most AV serotypes may be excreted in faeces, sometimes for long periods, as with AN' group C [4]. The role of AV other than EAV' in gastroenteritis has recently been suspected [5], although their causal role has not been proved.EAV are difficult to culture and alternative methods, such as immunoassay techniques [6], DNA restriction analysis [7] or molecular hybridization [8], are currently used for diagnosis. EAV usually infect and cause symptoms in children up to 3 years old, but mainly in those 2 years old or younger [9]. Some aetiologic studies of hospitalized and outpatient subjects with diarrhoea have been carried out recently [10][11][12]. Although these studies are necessary in order to determine the importance of the aetiologic agent, the epidemiological results are relevant 21 2

New genome types of Ad3 and Ad7 were found among adenovirus (Ad) strains isolated from stools of children during epidemiological surveys made in São Paulo, Brazil, and Buenos Aires, Argentina. These were characterized by DNA analysis with 11 restriction endonucleases and showed a number of new restriction patterns, notably for BamHI, BcII, BgIII, HindIII, KpnI, and SmaI. Restriction maps of the genome types, named Ad3e1, Ad3e2, Ad3h, and Ad7h, were constructed and compared with those of Ad3p and Ad7p.

The objective of the present study was to determine rotavirus etiology and prevalence of the different rotavirus serotypes in Ecuadorian children younger than 5 years of age with gastroenteritis. Children (729) less than 5 years of age with acute diarrhea from either public or private primary health care centers in 10 different provinces of Ecuador, between March 2006 and August 2006 were included in the study. Rotavirus infection was diagnosed using a commercial immunoenzymatic test. Rotavirus isolated from stool samples was genotyped. Rotavirus was detected in the feces of 269 of the 729 children (37%) with diarrhea. The most prevalent G genotypes were G9 (46.1%) and G2 (27.2%), while the predominant P genotypes were P[8] (57%) and P[4] (29.5%). Among the single infections, the predominant P/G combinations were: P[8]G9 (56.9%) and P[4]G2 (32.6%). The present countrywide survey is one of the major studies for one single season in Latin America and the first in its class in Ecuador. The value of expanding laboratory capability throughout Latin America in order to monitor rotavirus strains over time, with special attention directed at those strains obtained from children who experience vaccine failure, is critical. Only continuous monitoring of rotavirus disease burden and genotype surveillance will provide this information.
