| Abstract: | Several viruses have been associated with acute gastroenteritis (AGE), and group
A rotavirus (RVA) and nor-ovirus (NoV) are the most prevalent. This study aimed
to assess their prevalence among children hospitalised for diarrhoea during a
three-year surveillance study. From May 2008-April 2011, overall positivity
rates of 21.6% (628/2904) and 35.4% (171/483) were observed for RVA and NoV,
respectively. The seasonality observed indicated distinct patterns when both
viruses were compared. This finding may explain why hospitalisation for AGE
remains constant throughout the year. Continuous AGE monitoring is needed to
better assess the patterns of infection. |
