“…As then the NoV GII.4 is continuously circulating in this area until now. Simultaneously, the NoV studies conducted in another regions also reported the detection of NoV with the GII.4 as a common genotype detected . In the survey between 2000 and 2016, 26 different human NoV genotypes have been identified ( Figure ).…”

Norovirus (NoV) and sapovirus (SaV) infections remain public health problems in Thailand, particularly, causing an acute gastroenteritis in people of all age groups. This review summarizes the epidemiology and genotype distribution of NoV and SaV in Thailand during the period of 2000-2016. The overall prevalence of NoV infection in patients with acute gastroenteritis of all age groups ranged from 0.09% to 44.7% while those of SaV were 0.0-15.0%. The majority of NoV genogroup detected was NoV GII with a small proportion of NoV GI. The NoV GII.4 was the most predominant genotype (63.4%) followed by GII.3 (15.0%), GII.6 (3.9%), GII.17 (3.3%), GII.13 (2.1%) and many other genotypes with small proportion. Furthermore, eight GII.4 variant strains and 11 different NoV recombinant strains had also been reported. For SaV, 10 different human SaV genotypes were detected including GI.1, GI.2, GI.4, GI.5, GII.1, GII.2, GII.3, GII.4, GIV.1, and GV.1.

Sapovirus (SaV) is an emerging cause of children gastrointestinal complications such as acute gastroenteritis (AGE). The aim of the present systematic review and metaanalysis was to estimate the global prevalence of the SaV in children and association of infection with SaVs and AGE in children based on case-control studies. Four international databases (PubMed, Scopus, Web of Sciences and Google Scholar) were used to retrieve English-language studies published between January 2000 and December 2020. Comprehensive Meta-Analysis software was applied to estimate the overall prevalence, publication bias and heterogeneity index. The pooled prevalence of SaV infection among children with gastroenteritis was 3.4% [95% confidence interval (CI): 2.9%-3.9%] based on a random-effects meta-analysis.Genogroup I was the dominant genogroup of SaV in children with gastroenteritis [2.2% (95% CI: 1.6%-3.0%)], association analysis showed that SaV was associated with gastroenteritis [OR: 1.843 (95% CI: 1.27-2.66)]. Given the significant prevalence of the virus in children, it is necessary to pay more attention to this situation.Therefore, preventive health measures in children should be a priority.

Noroviruses and sapoviruses associated with acute gastroenteritis in pediatric patients in Thailand: increased detection of recombinant norovirus GII.P16/GII.13 strains

Enteric caliciviruses, including noroviruses (NoVs) and sapoviruses (SaVs), are recognized as important etiologic agents of acute gastroenteritis (AGE) with considerable genetic diversity. In order to gain an overview of the molecular epidemiology of human NoVs and SaVs in children hospitalized with AGE in Chiang Mai, Thailand, a total of 889 fecal specimens were collected from 2012 to 2014 and screened for NoVs and SaVs. Out of 889 fecal specimens, 154 (17.3%) and 6 (0.7%) were positive for NoV GII isolates and SaV, respectively. Among the NoV GII, 10 different genotypes were identified with genotype GII.4 being predominant (103 strains), followed by GII.3 (17 strains), GII.13 (13 strains), GII.1 (7 strains), GII.6 (7 strains), GII.7 (2 strains), GII.17 (2 strains), and one each of GII.2, GII.15, and GII.21 genotypes. It was observed that four variants of NoV GII.4 (Den Haag 2006b, Apeldoorn 2007, New Orleans 2009, Sydney 2012) were detected from 2012 to 2014. Analysis of partial nucleotide sequences of RdRp and VP1 of the emerging NoV GII.13 strains (9 of 13 strains) revealed that they all were GII.P16/GII.13 recombinants. In addition, four different genotypes of SaV, GI.1 (2 strains), GII.1 (1 strain), GII.4 (2 strains), and GIV.1 (1 strain) were detected. The data revealed heterogeneity and a highly dynamic distribution of NoV and SaV genotypes circulating in children admitted to hospitals with AGE in Chiang Mai, Thailand, during the period of 2012 to 2014.
