Global prevalence of norovirus gastroenteritis after emergence of the GII.4 Sydney 2012 variant: a systematic review and meta-analysis. Front Public Health 2024; 12:1373322. [PMID: 38993708 PMCID: PMC11236571 DOI: 10.3389/fpubh.2024.1373322] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Accepted: 05/30/2024] [Indexed: 07/13/2024] Open
Abstract
Introduction Norovirus is widely recognized as a leading cause of both sporadic cases and outbreaks of acute gastroenteritis (AGE) across all age groups. The GII.4 Sydney 2012 variant has consistently prevailed since 2012, distinguishing itself from other variants that typically circulate for a period of 2-4 years. Objective This review aims to systematically summarize the prevalence of norovirus gastroenteritis following emergence of the GII.4 Sydney 2012 variant. Methods Data were collected from PubMed, Embase, Web of Science, and Cochrane databases spanning the period between January 2012 and August 2022. A meta-analysis was conducted to investigate the global prevalence and distribution patterns of norovirus gastroenteritis from 2012 to 2022. Results The global pooled prevalence of norovirus gastroenteritis was determined to be 19.04% (16.66-21.42%) based on a comprehensive analysis of 70 studies, which included a total of 85,798 sporadic cases with acute gastroenteritis and identified 15,089 positive cases for norovirus. The prevalence rate is higher in winter than other seasons, and there are great differences among countries and age groups. The pooled attack rate of norovirus infection is estimated to be 36.89% (95% CI, 36.24-37.55%), based on a sample of 6,992 individuals who tested positive for norovirus out of a total population of 17,958 individuals exposed during outbreak events. Conclusion The global prevalence of norovirus gastroenteritis is always high, necessitating an increased emphasis on prevention and control strategies with vaccine development for this infectious disease, particularly among the children under 5 years old and the geriatric population (individuals over 60 years old).

[PMID: 38276149 PMCID: PMC10818385 DOI: 10.3390/pathogens13010003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Revised: 12/07/2023] [Accepted: 12/11/2023] [Indexed: 01/27/2024] Open
Abstract
Norovirus stands out as a leading cause of acute gastroenteritis (AGE) worldwide, affecting all age groups. In the present study, we investigated fecal samples from medically attended AGE patients received from nine Brazilian states, from 2019 to 2022, including the COVID-19 pandemic period. Norovirus GI and GII were detected and quantified using RT-qPCR, and norovirus-positive samples underwent genotyping through sequencing the ORF1/2 junction region. During the four-year period, norovirus prevalence was 37.2%, varying from 20.1% in 2020 to 55.4% in 2021. GII genotypes dominated, being detected in 92.9% of samples. GII-infected patients had significantly higher viral concentrations compared to GI-infected patients (median of 3.8 × 107 GC/g and 6.7 × 105 GC/g, respectively); and patients aged >12-24 months showed a higher median viral load (8 × 107 GC/g) compared to other age groups. Norovirus sequencing revealed 20 genotypes by phylogenetic analysis of RdRp and VP1 partial regions. GII.4 Sydney[P16] was the dominant genotype (57.3%), especially in 2019 and 2021, followed by GII.2[P16] (14.8%) and GII.6[P7] (6.3%). The intergenogroup recombinant genotype, GIX.1[GII.P15], was detected in five samples. Our study is the first to explore norovirus epidemiology and genotype distribution in Brazil during COVID-19, and contributes to understanding the epidemiological dynamics of norovirus and highlighting the importance of continuing to follow norovirus surveillance programs in Brazil.

Abstract
Norovirus (NoV) is a leading cause of epidemic and sporadic gastroenteritis in people of all ages. Humans are the primary source of NoV and household contact is one of the risk factors for NoV transmission. However, the mechanisms underlying person-to-person NoV transmission are poorly understood. Here we conducted a survey to profile the frequency and characteristics of intrafamily NoV transmission. Stool samples were collected every week from three households between 2016 and 2020; the total number of samples was 1105. The detection of NoV and the genotyping were performed by reverse transcription-polymerase chain reaction targeting the capsid region and direct sequencing methods. NoV was detected in 3.4% of all samples. Eight NoV genotypes were identified. The most common genotype was GII.17, followed in order by GII.6, GI.6, GII.4, GI.3, and GI.2/GI.8/GI.9. Most NoV-positive samples were obtained from asymptomatic individuals. The highest number of NoV transmissions was found in household 3 (6 infections), followed by household 2 (2 infections), while household 1 had no NoV transmission, suggesting that asymptomatic NoV carriers play a major role in infection as NoV reservoirs in the households. Further clarification of the mode of infection will contribute to improved understanding and an appropriate prevention.

Abstract
Noroviruses (NoVs) are a global concern, causing widespread outbreaks and sporadic acute gastroenteritis (AGE) cases across all age groups. Recent research has shed light on the emergence of novel recombinant strains of NoV in various countries. To delve deeper into this phenomenon, we extensively analyzed 1,175 stool samples collected from Japanese infants and children with AGE from six different prefectures in Japan over three years, from July 2018 to June 2021. Our investigation aimed to determine the prevalence and genetic characteristics of NoV associated with sporadic AGE while exploring the possibility of detecting NoV recombination events. Among the analyzed samples, we identified 355 cases positive for NoV, 11 cases attributed to GI genotypes, and 344 associated with GII genotypes. Notably, we discovered four distinct GI genotypes (GI.2, GI.3, GI.4, and GI.6) and seven diverse GII genotypes (GII.2, GII.3, GII.4, GII.6, GII.7, GII.14, and GII.17). The predominant genotypes were GII.4 (56.4%; 194 out of 344), followed by GII.2 and GII.3. Through dual genotyping based on sequencing of the ORF1/ORF2 junction region, we identified a total of 14 different RdRp/capsid genotypes. Of particular interest were the prevalent recombinant genotypes GII.4[P31] and GII.2[P16]. Notably, our study revealed a decrease in the number of children infected with NoV during and after the COVID-19 pandemic. These findings underscore the importance of continuous NoV surveillance efforts.

J Clin Virol 2021; 143:104968. [PMID: 34509928 DOI: 10.1016/j.jcv.2021.104968] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Revised: 08/18/2021] [Accepted: 08/27/2021] [Indexed: 11/17/2022]
Abstract
Globally, norovirus (NoV) has become one of the important causes of acute gastroenteritis (AGE) in children. It is responsible for death of children younger than 5 years in developing countries. Although there is limited information and the rate of child mortality caused by diarrhea is low in Malaysia, the burden of diarrhea is high, especially in Sabah. NoV GI, GII and GIV genogroups are known to infect humans, and GII.4 is the predominant genotype distributed worldwide. Better understanding of the etiology of NoV will help to inform policies for prevention and control. The aim of this study was to determine the burden and genotype distribution of NoV in children younger than 5 years with AGE who attended health-care facilities in Sabah, Malaysia. Diarrhea stool samples were collected from 299 children with AGE and NoV was detected by amplifying the capsid and RNA-dependent RNA polymerase gene and reverse transcription-polymerase chain reaction (RT-PCR) analysis. Nucleotide sequencing of the amplicons was used for genotypes and phylogenetic analyses . NoV-positive stool samples were found in 17.7% (53/299) among which 13/53 (24.5%), 38/53 (71.7%), and 2/53 (3.8%) identified as NoV GI, GII and combination of GI and GII, respectively. The most common genotypes were GII.3 [P12] (80%) followed by GII.6 [P7] (13.3%), and GII.17 [P17] (6.7%). In the phylogenetic tree, all Sabahan NoV samples were shown to share ancestry with their respective genotype from predominantly East Asian countries and to some extent Australia and Europe. However, the Sabahan strains formed independent clusters with significant bootstrap values, indicating a clonal spread after the strains had entered Sabah.

Abstract
Noroviruses are considered an important cause of acute gastroenteritis (AGE) across all age groups. Here, we investigated the incidence of norovirus, genotypes circulation, and norovirus shedding in AGE stool samples from outpatients in Brazil. During a two-year period, 1546 AGE stool samples from ten Brazilian states were analyzed by RT-qPCR to detect and quantify GI and GII noroviruses. Positive samples were genotyped by dual sequencing using the ORF1/2 junction region. Overall, we detected norovirus in 32.1% of samples, with a massive predominance of GII viruses (89.1%). We also observed a significant difference between the median viral load of norovirus GI (3.4×105 GC/g of stool) and GII (1.9×107 GC/g). The most affected age group was children aged between 6 and 24 m old, and norovirus infection was detected throughout the year without marked seasonality. Phylogenetic analysis of partial RdRp and VP1 regions identified six and 11 genotype combinations of GI and GII, respectively. GII.4 Sydney[P16] was by far the predominant genotype (47.6%), followed by GII.2[P16], GII.4 Sydney[P31], and GII.6[P7]. We detected, for the first time in Brazil, the intergenogroup recombinant genotype GIX.1[GII.P15]. Our study contributes to the knowledge of norovirus genotypes circulation at the national level, reinforcing the importance of molecular surveillance programs for future vaccine designs.

Abstract
In the post rotavirus vaccine era, norovirus (NoV) plays an increasingly important role in epidemic and sporadic gastroenteritis among children. This study was designed to provide an updated meta-analytic review of the prevalence of NoV among paediatric patients with gastroenteritis and to clarify the relationship between NoV infection and gastroenteritis. Systematic searches of the literature for potentially relevant studies were carried out from 1 January 2015 to 29 May 2020. The inverse variance method was chosen for weighting of the studies, and the random-effects model was used to analyse data. To determine the association between NoV infection and gastroenteritis in children, pooled odds ratio (OR) and its 95% confidence interval (CI) were computed for case-control studies. The pooled prevalence of NoV infection among 12,0531 children with gastroenteritis from 45 countries across the world was 17.7% (95% CI: 16.3%-19.2%). There were 28 studies with a case-control design, and the pooled prevalence of NoV infection among 11,954 control subjects was 6.7% (95% CI: 5.1%-8.8%). The pooled OR of the association of NoV infection and gastroenteritis was 2.7 (95% CI: 2.2-3.4). The most common NoV genotypes were GII.4 (59.3%) and GII.3 (14.9%). The highest frequency of NoV was found in the age group below 1 year. Our findings indicated a substantial burden of gastroenteritis caused by NoV globally, with GII.4 and GII.3 the major genotypes responsible for the majority of NoV-associated gastroenteritis cases among children. Younger age and male sex can be considered risk factors for NoV-associated gastroenteritis among children.

Molecular epidemiology and genetic diversity of norovirus infection in children hospitalized with acute gastroenteritis in East Java, Indonesia in 2015-2019. INFECTION GENETICS AND EVOLUTION 2021; 88:104703. [PMID: 33401005 DOI: 10.1016/j.meegid.2020.104703] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Revised: 12/02/2020] [Accepted: 12/30/2020] [Indexed: 12/12/2022]
Abstract
Noroviruses are recognized as a leading cause of outbreaks and sporadic cases of acute gastroenteritis (AGE) among individuals of all ages worldwide, especially in children <5 years old. We investigated the epidemiology of noroviruses among hospitalized children at two hospitals in East Java, Indonesia. Stool samples were collected from 966 children with AGE during September 2015-July 2019. All samples were analyzed by reverse transcription-polymerase chain reaction (RT-PCR) for the amplification of both the RNA-dependent RNA polymerase (RdRp) and the capsid genes of noroviruses. The genotypes were determined by phylogenetic analyses. In 2015-2019, noroviruses were detected in 12.3% (119/966) of the samples. Children <2 years old showed a significantly higher prevalence than those ≥2 years old (P = 0.01). NoV infections were observed throughout the year, with the highest prevalence in December. Based on our genetic analyses of RdRp, GII.[P31] (43.7%, 31/71) was the most prevalent RdRp genotype, followed by GII.[P16] (36.6%, 26/71). GII.[P31] was a dominant genotype in 2016 and 2018, whereas GII.[P16] was a dominant genotype in 2015 and 2017. Among the capsid genotypes, the most predominant norovirus genotype from 2015 to 2018 was GII.4 Sydney_2012 (33.6%, 40/119). The most prevalent genotype in each year was GII.13 in 2015, GII.4 Sydney_2012 in 2016 and 2018, and GII.3 in 2017. Based on the genetic analyses of RdRp and capsid sequences, the strains were clustered into 13 RdRp/capsid genotypes; 12 of them were discordant, e.g., GII.4 Sydney[P31], GII.3[P16], and GII.13[P16]. The predominant genotype in each year was GII.13[P16] in 2015, GII.4 Sydney[P31] in 2016, GII.3[P16] in 2017, and GII.4 Sydney[P31] in 2018. Our results demonstrate high detection rates and genetic diversity of norovirus GII genotypes in pediatric AGE samples from Indonesia. These findings strengthen the importance of the continuous molecular surveillance of emerging norovirus strains.

Abstract
Group A rotaviruses (RVA) are the leading cause of acute gastroenteritis (AGE) in young (aged <5 years) children. Several studies showed that RVA is one of the main cause of nosocomial gastroenteritis in hospitalized pediatric population worldwide, with an incidence ranging from 8 to 33 cases per 100 hospitalized children. Nosocomial infections, in which AGE symptoms develop at least 2 days after admission, may severely affect children already admitted to hospital for other causes. This study aimed to define the trends of the RVA genotypes through statistical analysis of the data obtained by the rotavirus surveillance in Umbria in 10 consecutive seasons, from 2007-2008 to 2016-2017, with update information on hospital-acquired RVA AGE. During RVA gastroenteritis surveillance in Umbria (Italy) in 2007 to 2017, a total of 741 RVA positive faecal samples were collected from children hospitalized with AGE, and RVA strains were genotyped following standard EuroRotaNet protocols. Of the 741 analyzed samples, 75 (10%) were reported to be hospital-acquired. Comparing the distributions of the RVA genotypes circulating in the community or associated with nosocomial infections, we observed a different distribution of genotypes circulating inside the hospital wards, with respect to those observed in the community except in 2010 to 2011, 2011 to 2012, and 2012 to 2013 when G1P[8], G4P[8] and the novel strain G12P[8] caused a large community- and hospital-acquired outbreak. Of the 741 analyzed samples, 75 (10%) were reported to be hospital-acquired. Comparing the distributions of the RVA genotypes circulating in the community or associated with nosocomial infections, we observed a different distribution of genotypes circulating inside the hospital wards, with respect to those observed in the community except in 2010 to 2011, 2011 to 2012, and 2012 to 2013 when G1P[8], G4P[8], and the novel strain G12P[8] caused a large community- and hospital-acquired outbreak. The information from this study will be useful to implement guidelines for preventing nosocomial RVA AGE, which should include an improved management of the hospitalized patients and an increase in vaccination coverage.

Abstract
Norovirus (NoV) is one of the most important viral causes of acute gastroenteritis (AGE) in children worldwide. Only a few studies have reported AGE with NoV-positive in some cities in Indonesia. This study aimed to investigate the incidence and clinical characteristic of NoV infection, and also genotype distribution of NoV in children with AGE in Jambi, as the capital and the largest city of Jambi province, Indonesia. Stool samples were collected from children (≤15 years of age) with AGE at three participating hospitals in Jambi from February to April 2019. The detection of NoV and its genotyping were carried out by reverse-transcriptase polymerase chain reaction and direct sequencing. Of the 91 stool samples collected, 14 (15.4%) were positive for NoV. Fever, vomiting, and severe diarrhea were commonly observed in AGE with NoV, while level of dehydration was statistically significant difference between children with NoV-positive and those with NoV-negative. The most prevalent genotype was GI.4 (42.9%), followed by GII.6 (28.6%) and some other genotypes. Interestingly, this study found the predominance of GI.4, differed from previous reports in Indonesia. Continuously investigation of the circulating genotype is needed to control the NoV-infected AGE.

Protective action of Bacillus clausii probiotic strains in an in vitro model of Rotavirus infection. Sci Rep 2020; 10:12636.

Abstract
Rotavirus is the most common cause of acute gastroenteritis (AGE) in young children. Bacillus clausii (B. clausii) is a spore-forming probiotic that is able to colonize the gut. A mixture of four B. clausii strains (O/C, T, SIN and N/R) is commonly used for the treatment of AGE, and it has been demonstrated that it can reduce the duration and severity of diarrhea in children with AGE. Few studies have sought to characterize the mechanisms responsible for such beneficial effects. Intestinal effects of probiotics are likely to be strain-specific. We conducted a series of in vitro experiments investigating the activities of this mixture of B. clausii strains on biomarkers of mucosal barrier integrity and immune function in a cellular model of Rotavirus infection. B. clausii protected enterocytes against Rotavirus-induced decrease in trans-epithelial electrical resistance, and up-regulated expression of mucin 5AC and tight junction proteins (occludin and zonula occludens-1), all of which are important for effective mucosal barrier function. B. clausii also inhibited reactive oxygen species production and release of pro-inflammatory cytokines (interleukin-8 and interferon-β) in Rotavirus-infected cells, and down-regulated pro-inflammatory Toll-like receptor 3 pathway gene expression. Such mechanisms likely contributed to the observed protective effects of B. clausii against reduced cell proliferation and increased apoptosis in Rotavirus-infected enterocytes.

Abstract
We analyzed 46 pediatric fecal samples collected between the years 1997 and 2000 to retrospectively evaluate the norovirus strains circulating during that era and to identify possible re-emergence patterns. From the tested fecal samples, we detected GII.1, GII.3, GII.4 (95/96-US) and GII.6 strains. Most importantly, two novel polymerase genotypes (GI.PNA4 and GII.PNA7) were detected during the study. Two possible recombinant strains (GII.6[P7] and GII.3[P29]) were identified and SimPlot analysis confirmed that GII.6[P7] is a recombinant strain. The study emphasizes the importance of retrospective evaluation of human fecal samples in obtaining a better understanding of norovirus circulation, re-emergence and evolution.

Abstract
Background: The objective of this study was to investigate the clinical manifestation of norovirus infection between norovirus genogroup and severity of acute diarrhea in pediatric patients at the Dr. Soetomo Hospital, Surabaya, Indonesia. Methods: This cross-sectional study involved 31 participants aged 1-60 months admitted to the hospital with acute diarrhea from April 2012 to March 2013. Norovirus genogroups (GI and II) were identified from patient stool using reverse transcription polymerase chain reaction (RT-PCR). Severity was measured using the Ruuska and Vesikari scoring system. Results: In total, 94 stool samples were obtained, of which 31 (19%) were norovirus positive. Norovirus GI was found in one sample with mild diarrhea. Norovirus GII was found in 30 samples (96.8%); one sample with mild diarrhea (3.3%), 20 samples with moderate diarrhea (66.7%), and nine samples with severe diarrhea (30%). Conclusion: Norovirus GII was the most prevalent cause of acute diarrhea and 30% of the cases manifested as severe diarrhea.
