The epidemiology of acute viral gastroenteritis in hospitalized children in Cordoba city, Argentina: an insight of disease burden

Abstract

Information concerning the disease burden of viral gastroenteritis has important implications for the use and monitoring the impact of public health policies. The present study, carried out in Córdoba city, Argentina, documents the epidemiology of severe viral diarrhea as well as the burden of viral gastrointestinal disease in the hospital children admission. A total of 133 stools were collected from hospitalized children (Town Childhood Hospital) suffering from acute diarrhea and studied for the presence of Group A rotavirus, astrovirus and adenovirus 40/41 by enzyme-immuno assay, between November 1997 and October 1998. Enteric viruses accounted for 42.1% of the total diarrheal cases analyzed. Group A rotaviruses, astroviruses, adenoviruses 40/41 and mixed infections were found in 35.3, 4.5, 1.5, and 0.8% studied specimens respectively. We estimated that 1 in 27 children in the 0-35 month-old cohort/range would be annually hospitalized for a viral gastroenteritis illness. The major impact on viral diarrhea lies on rotaviral infection, accounting for 84.0% of the viral diarrheal cases analyzed and for approximately one third of severe diarrheas requiring hospital admission in Córdoba City, Argentina.

Astrovirus infection in children living in the Central West region of Brazil

“…In this study, a higher detection rate of astrovirus in cases of AG (4.3%) was observed, as compared to non-diarrheic patients (0.5%) (p < 0.05). This result is comparable to those from other studies where viral detection rates in cases of AG ranged from 1.5 to 20% (Mitchell et al 1999, Giordano et al 2001, Denno et al 2005. In contrast, results from children without gastroenteritis are lower than those observed in other studies where detection rates of 1.2 to 5.7% were yielded considering the same population (Pennap et al 2002, Riechmann et al 2004.…”

“…The astroviruses are recognized as one of the most common cause of viral gastroenteritis in infants and young children in worldwide (Giordano et al 2001) and its seasonality is variable according to the geographic region (Naficy et al 2000, Guix et al 2002. The main symptom of the astrovirus infections is a watery and mild diarrhea, which generally results in mild diarrheic disease (Matsui & Greenberg 2001), although a recent study has described astrovirus infection related to severe dehydrating gastroenteritis among isolated Brazilian communities (Gabbay et al 2006).…”

Increase in the detection rate of viral and parasitic enteric pathogens among Egyptian children with acute diarrhea

“…Viruses, including rotavirus (RV), norovirus (NoV), enteric adenovirus 40/41 (AdV) and astrovirus (AsV) have been shown to be important causes of acute diarrhea in children during the early years of life [8][9][10][11]. RV and NoV are considered the most important causative agents of viral gastroenteritis [12,13] and surveillance studies have demonstrated that RV is one of the most common causes of diarrhea among children seeking hospital care for their illness [14].…”

Astrovirus (HAstV) como agente causal de diarrea en niños Colombianos: Siete años de estudio

“…La tabla 2 se realizó para determinar la procedencia y el año en el cual se obtuvo cada cepa y relacionarlo con el resultado del comportamiento filogenético por NJ. Cuando se evalúan los HAstV, se detectan prevalencias muy bajas que no alcanzan a elevar el porcentaje de las diarreas diagnosticadas en un tipo de poblaciones como la nuestra (13)(14)(15)(16)(17).…”
