“…The results are generally consistent with previously published data on rotavirus [Nelson et al, 2004[Nelson et al, , 2005a and norovirus [Ho et al, 2006] in Hong Kong. Our results suggest that the proportion of acute gastroenteritis cases caused by norovirus has risen compared to 15-20 years ago (1.9%) [Chan et al, 1994].…”

“…This may be the result of a particular outbreak, but is also consistent with previous data also reported a winter predominance of rotavirus in Hong Kong, China and worldwide [Chan et al, 1994;Nelson et al, 2004;Orenstein et al, 2007]. It has been reported that norovirus peaks between October and March in Hong Kong [Nelson et al, 2005a;Ho et al, 2006] and elsewhere . Our results however, showed that the number of norovirus detected remained fairly stable throughout the 8 months.…”

A total of 209 stool samples were collected from pediatric patients admitted for acute gastroenteritis in a hospital in Hong Kong, during an 8-month period from January to August 2008, and were tested for the presence of rotavirus, norovirus, sapovirus, adenovirus, and astrovirus using a multiplex RT-PCR assay. The most common virus was rotavirus group A (59 of 209, 28%, mainly serotypes G1, G2, G3, and G9), followed by norovirus group II (48 of 209, 23%), adenovirus (7 of 209, 3%, serotypes 2, 3, and 41), and sapovirus (2 of 209, 1%). Interestingly, none of the specimens in this study were positive for astrovirus. One sample was found to have a dual infection with both norovirus group II and adenovirus. The results support the importance of norovirus as a causative agent of diarrhea in children, which may be underestimated by the current routine diagnostic testing.

“…The World Health Organization (WHO) and UNICEF estimate that almost 2.5 billion episodes of diarrhea occur annually in children <5 year of age in developing countries, with more than 80% of the episodes occurring in Africa and South Asia, 46% and 38%, respectively [1]. In India diarrhea is the third leading killer of children, responsible for 13% of all deaths in children below 5 years of age and kills an estimated 300,000 children in India each year [2].…”

Objectives: To estimate the prevalence and seasonal distribution of Rotavirus diarrhea in hospitalized children less than 5 years in South Rajasthan. Design: Cross-sectional study. Setting: Bal-Chikitsalaya, RNT Medical College, Udaipur, Rajasthan. Methods: Hospitalized children less than 5 years admitted for acute diarrhea were examined and standardized proforma was used to collect the demographic and clinical profile of the children. Severity of the illness was classified as per Vesikari scoring system and the dehydration was treated as per WHO protocol. Stool samples were collected and tested for gross appearance, routine microscopy, pH, reducing sugar and Rotaviral antigen by a commercial enzyme Immunoassay kit (SD BIOLINE KIT). Results: Out of 300 children, 94(31.33%) were positive for Rotavirus. The prevalence of Rotaviral diarrhea in children was as follows: <6 months-14.8%, 6-12 months-45.7%, 12-24 months-38.3% and >24 months-0.01%. Rotaviral diarrhea was more common during Winter and Spring months (September to April) 91.4%, with highest prevalence in the months of November (52%), December (68%) and January (56%). Rotavirus negative diarrhea had high prevalence (62.6%) during summer and monsoon months (March-August). Out of 94 rotavirus positive children, 6 cases (6.38%) had no dehydration, 55(58.51%) had some dehydration and 33 (35.10%) had severe dehydration. Among the Rotavirus positive children, vomiting was present in 70 (74.46%) children and fever in 52 (55.31%) children. Conclusions: The prevalence of Rotaviral diarrhea in children less than 5 years in southern Rajasthan is high and it is more common during Winter and Spring seasons of the year.
