Abstract

SIQUEIRA, Jones Anderson Monteiro et al. Group A rotavirus and norovirus display sharply distinct seasonal profiles in Belém, northern Brazil. Mem. Inst. Oswaldo Cruz [online]. 2013, vol.108, n.5, pp.661-664. ISSN 0074-0276.  http://dx.doi.org/10.1590/S0074-02762013000500020.

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.

Keywords : rotavirus; norovirus; seasonality.
