Resume

Les analyses en biologie moléculaire des virus des gastroentérites ont permis à la lois de mieux connaître les agents pathogénes mais aussi de développer de nouvelles techniques de diagnostic.

Dans les pays défavorisés, les gastroentérites sont une cause fréquente de décès chez l'enfant de moins de 5 ans, elles sont dues à de multiples agents infectieux. Dans les pays développés, la mortalité est peu élevée, mais la majorité des diarrhées aiguës est à l'origine d'hospitalisations et de consultations médicales.

Les causes les plus fréquentes des diarrhées aiguës de l'enfant sont les infections virales représentées par quatre familles principales : les rotavirus, les calicivirus, les astrovirus et les adénovirus.

Les gastroentérites virales sont caractérisées par deux profils épidémiologiques : les diarrhées aiguës qui sont endémiques chez le jeune enfant et les épidémies sporadiques qui surviennent à tousles âges.

Le rotavirus est la cause des gastroentérites les plus sévàres, en particulier chez l'enfant de moins de six mois.

Abstract

The molecular characterization of gastroenteritis viruses has led to advances both in our understanding of the pathogens themselves and in development of a new generation of diagnostics.

In developing countries, gastroenteritis is a common cause of death in children under 5 years that can be linked to a wide variety of pathogens. In developed countries, while deaths from diarrhoea are less common, much illness leads to hospitalization or doctor visits.

Much of the gastroenteritis in children is caused by viruses belonging to four distinct families: rotaviruses, caliciviruses, astroviruses and adenoviruses. Viral gastroenteritis occurs with two epidemiologic patterns, diarrhoea that is endemic in children and outbreaks that affect people of all ages. Rotavirus infection causes severe gastroenteritis, particularly in infants under six months of age.
