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).

Effect of COVID-19 protective measures on the epidemiology characteristics of rotavirus, adenovirus, and coinfections among pediatric patients with acute gastroenteritis in Hangzhou, China. Microbiol Spectr 2024; 12:e0400723. [PMID: 38345390 PMCID: PMC10913746 DOI: 10.1128/spectrum.04007-23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Accepted: 01/20/2024] [Indexed: 03/06/2024] Open
Abstract
Human rotavirus (RV) and adenovirus (AdV) have been recognized as common enteric viruses associated with viral acute gastroenteritis (AGE) in children aged<5 years. However, with the transmission of coronavirus disease 2019 (COVID-19) has been suppressed due to various aggressive and effective anti-epidemic measures, the prevalence of other viruses has also been affected. Therefore, this study aimed to investigate the impact of COVID-19 on the epidemiological characterization of RV, AdV, and coinfections among children with AGE in a hospital in Hangzhou from 2019 to 2023. The overall changes, seasonal distribution, and age distribution of enteroviruses were analyzed based on 5 years of records. All data were analyzed using SPSS 27.0. A total of 102,049 samples were analyzed from January 2019 to August 2023, and among them 15,911 (15.59%) were positive specimens, 11,646 (11.41%) were RV-positive, 4,057 (3.98%) were AdV-positive, and 208 (0.20%) were coinfection. The positive rate among males was 15.54%, while among females was 15.66% with a male-to-female ratio of 1.42:1. There was no significant difference in the positive rates of enterovirus infection between males and females. Significant associations were found between the month group and RV/AdV infection, with RV detection peaking in winter (74.18%) and early spring (29.22%), while AdV has a high prevalence in summer (16.03%) and spring (12.71%). The age group was also found to be significantly associated with RV/AdV infection, with RV being most prevalent in the 1-3-year-old age group (16.99%), while AdV was highest in the 3-5-year-old age group (8.10%).IMPORTANCEThis study highlights the epidemiological changes of rotavirus (RV), adenovirus (AdV), and coinfections in children with acute gastroenteritis (AGE) before, during, and after coronavirus disease 2019 (COVID-19) periods. There was a highly statistically significant difference in the positive rates of RV-positive, AdV-positive, and coinfection (P < 0.001), indicating that RV remains the main pathogen causing AGE. It emphasizes the importance of continuous surveillance of RV and AdV at both local and global levels. Regular surveillance of prevalent rotavirus strains will facilitate the development of new inactivated rotavirus vaccines and aid in disease prevention and control.

INFECTION, GENETICS AND EVOLUTION : JOURNAL OF MOLECULAR EPIDEMIOLOGY AND EVOLUTIONARY GENETICS IN INFECTIOUS DISEASES 2023; 115:105499. [PMID: 37734510 DOI: 10.1016/j.meegid.2023.105499] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 08/31/2023] [Accepted: 09/05/2023] [Indexed: 09/23/2023]
Abstract
While the GII.4 norovirus was the predominant genotype, non-GII.4 genotype was increasingly focused since the non-GII.4 genotype caused regional epidemics. In this study, the detection rate was16.51% (183/1108) in Ningxia from January to December 2020. Among identified genotypes, GII.4[P31] and GII.4[P16] were the dominant genotypes (n = 20 and 18, respectively) while GII.6[P7] was the main type (n = 6) in non-GII.4 strains which was mainly detected in from May to July. The whole genome sequences of the norovirus diarrhea samples identified as GII.6 [P7] with Ct ≤ 30 collected in 2020 were determined. In this study, the complete genome sequences of norovirus strains PL20-044 and QTX20-071 were identified and analyzed phylogenetically. Phylogenetic analysis of the ORF1and ORF2 regions showed that these strains evolved from the GII·P7-GII.6 strains detected in recent years from different country. The results showed that PL20-044 had intra-type recombination with GII·P7-GII.6c and GII·P7-GII.6a, while QTX20-071 had intre-type recombination within GII·P7-GII.6a. The evolutionary rates of the RdRp gene region of the GII·P7 genotype and the VP1 gene region of the GII.6 genotype were 2.91 × 10-3 (95%HPDs2.32-3.51 × 10-3) and 2.61 × 10-3 (95%HPDs2.14-3.11 × 10-3) substitutions/site/year, respectively. Comparative analysis of the amino acid mutation sites in VP1 with the GII·P7-GII.6a strains before 1997, the later detected strains have changed in aa131 and aa354. Moreover, PL20-044 strains showed special mutations at aa316 and aa395. These results help to understand the norovirus genotype circulating in the human population in Ningxia, and discover the evolutionary characteristics of the GII·P7-GII.6 strain.

Prevalence and Characterization of Gastroenteritis Viruses among Hospitalized Children during a Pilot Rotavirus Vaccine Introduction in Vietnam. Viruses 2023; 15:2164. [PMID: 38005842 PMCID: PMC10675811 DOI: 10.3390/v15112164] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 10/16/2023] [Accepted: 10/24/2023] [Indexed: 11/26/2023] Open
Abstract
Rotavirus (RV), norovirus (NoV), sapovirus (SaV), and human astrovirus (HAstV) are the most common viral causes of gastroenteritis in children worldwide. From 2016 to 2021, we conducted a cross-sectional descriptive study to determine the prevalence of these viruses in hospitalized children under five years old in Nam Dinh and Thua Thien Hue provinces in Vietnam during the pilot introduction of the RV vaccine, Rotavin-M1 (POLYVAC, Hanoi, Vietnam). We randomly selected 2317/6718 (34%) acute diarrheal samples from children <5 years of age enrolled at seven sentinel hospitals from December 2016 to May 2021; this period included one year surveillance pre-vaccination from December 2016 to November 2017. An ELISA kit (Premier Rotaclone®, Meridian Bioscience, Inc., Cincinnati, OH, USA) was used to detect RV, and two multiplex real-time RT-PCR assays were used for the detection of NoV, SaV and HAstV. The prevalence of RV (single infection) was reduced from 41.6% to 22.7% (p < 0.0001) between pre- and post-vaccination periods, while the single NoV infection prevalence more than doubled from 8.8% to 21.8% (p < 0.0001). The SaV and HAstV prevalences slightly increased from 1.9% to 3.4% (p = 0.03) and 2.1% to 3.3% (p = 0.09), respectively, during the same period. Viral co-infections decreased from 7.2% to 6.0% (p = 0.24), mainly due to a reduction in RV infection. Among the genotypeable samples, NoV GII.4, SaV GI.1, and HAstV-1 were the dominant types, representing 57.3%, 32.1%, and 55.0% among the individual viral groups, respectively. As the prevalence of RV decreases following the national RV vaccine introduction in Vietnam, other viral pathogens account for a larger proportion of the remaining diarrhea burden and require continuing close monitoring.

Abstract
Norovirus (NoV) is a major pathogen that causes acute gastroenteritis (AGE) in people of all ages, especially in children. In this study, we investigated the molecular epidemiological characteristics of NoV in children with AGE in Shanghai from 2018 to 2021. The overall detection rate of NoV was 11.9% (181/1545), with annual detection rates of 9.4% (36/381), 13.6% (29/213), 5.8% (13/226) and 14.2% (103/725), respectively. Of note, the prevalence of NoV in 2020 was significantly lower than that in 2018-2019 (10.9%, 65/594) (P = 0.023) and 2021 (14.2%, 103/725) (P = 0.000). The 181 NoV strains identified in this study were classified into the GI group (1.1%, 2/181), GII group (98.3%, 178/181) and GIX group (0.6%, 1/181) according to the VP1 gene. The most common NoV VP1 genotype was GII.4 Sydney_2012 (63.5%, 115/181), followed by GII.3 (19.9%, 36/181) and GII.2 (9.4%, 17/181). For P genotypes, 174 strains were sequenced successfully according to the RdRp gene, and the predominant genotype was GII.P16 (44.8%, 78/174), followed by GII.P31 (25.9%, 45/174) and GII.P12 (21.3%, 37/174). Among the 174 cases, GII.4 Sydney_2012[P16] (36.8%, 64/174) was the dominant genotype, followed by GII.4 Sydney_2012[P31] (25.3%, 44/174), GII.3[P12] (20.1%, 35/174) and GII.2[P16] (8.0%, 14/174). In particular, the dominant genotypes in Shanghai changed from GII.4 Sydney_2012[P31] in 2018-2019 to GII.4 Sydney_2012[P16] in 2020-2021. This is the first report to describe the epidemiological changes in NoV infection before and during the COVID-19 pandemic in Shanghai. These data highlight the importance of continuous surveillance for NoV in children with AGE in Shanghai.

Abstract
To understand the evolution of GII.P6-GII.6 and GII.P7-GII.6 strains, the prevalent human norovirus genotypes, we analysed both the RdRp region and VP1 gene in globally collected strains using authentic bioinformatics technologies. A common ancestor of the P6- and P7-type RdRp region emerged approximately 50 years ago and a common ancestor of the P6- and P7-type VP1 gene emerged approximately 110 years ago. Subsequently, the RdRp region and VP1 gene evolved. Moreover, the evolutionary rates were significantly faster for the P6-type RdRp region and VP1 gene than for the P7-type RdRp region and VP1 genes. Large genetic divergence was observed in the P7-type RdRp region and VP1 gene compared with the P6-type RdRp region and VP1 gene. The phylodynamics of the RdRp region and VP1 gene fluctuated after the year 2000. Positive selection sites in VP1 proteins were located in the antigenicity-related protruding 2 domain, and these sites overlapped with conformational epitopes. These results suggest that the GII.6 VP1 gene and VP1 proteins evolved uniquely due to recombination between the P6- and P7-type RdRp regions in the HuNoV GII.P6-GII.6 and GII.P7-GII.6 virus strains.

[PMID: 37344873 DOI: 10.1186/s12985-023-02105-z] [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: 02/25/2023] [Accepted: 06/17/2023] [Indexed: 06/23/2023] Open
Abstract
BACKGROUND Human adenovirus (HAdV) has been recognized as one of the common enteric viruses associated with acute gastroenteritis (AGE) in children. The aim of this study was carried out to illustrate the epidemiological characterization of HAdV Infections among children younger than 15 years in Shanghai during COVID-19. METHODS During May 2020 and April 2022, 1048 fecal samples were collected from children ≤ 15 years diagnosed with AGE in the Children's Hospital of Fudan University. HAdV was identified by PCR and sequenced with specific primers. All the obtained sequences were analyzed by MEGA (version 6.0). Demographic information and clinical features data were also collected and analyzed. RESULTS In total, 97 (9.3%, 97/1048) samples were detected to be HAdV during May 2020 and April 2022. We found an atypical upsurge in HAdV infection in the year 2021 after a major suppression in the year 2020. Approximately 84.5% (82/97) of HAdV-infected children were aged 0-60 months. Among the 97 HAdV-positive samples, only two species and five genotypes were detected. HAdV-F (88.7%, 86/97) was the most prevalent species and HAdV-F41 (87.6%, 85/97) was the most common genotype. Diarrhea, vomiting, and fever were the main clinical manifestations in children infected with HAdV. The children aged from 0 to 12 months showed simpler patterns of clinical presentation than those of children older than 13 months. CONCLUSIONS Our findings described the epidemiological changes of HAdV infection in children with AGE during the COVID-19, which further underscored the importance of continuous surveillance of HAdV at both local and global scales.

Abstract
Norovirus (NoV) is an important cause of viral acute gastroenteritis (AGE). To gain insights into the epidemiological characteristics and genetic diversity of NoV among children in Hubei, 1216 stool samples from children (≤ 5 years) obtained under AGE surveillance from January 2017 to December 2019 were analyzed. The results showed that NoV was responsible for 14.64% of AGE cases, with the highest detection rate in children aged 7-12 months (19.76%). Statistically significant differences were found between male and female infection rates (χ2 = 8.108, P = 0.004). Genetic analysis of RdRp and VP1 sequences showed that NoV GII genotypes were GII.4 Sydney [P31] (34.35%), GII.3 [P12] (25.95%), GII.2 [P16] (22.90%), GII.4 Sydney [P16] (12.98%), GII.17 [P17] (2.29%), GII.6 [P7] and GII.3 [P16] (each at 0.76%). GII.17 [P17] variants were divided into the Kawasaki323-like lineage and the Kawasaki308-like lineage. A unique recombination event was detected between strains of GII.4 Sydney 2012 and GII.4 Sydney 2016. Significantly, all GII.P16 sequences associated with GII.4/GII.2 obtained in Hubei were correlated with novel GII.2 [P16] variants that re-emerged in Germany in 2016. Antigenic site analysis of complete VP1 sequences from all GII.4 variants from Hubei identified notable variable residues of antibody epitopes. Genotyping under continuous AGE surveillance and observation of the antigenic sites of VP1 are important monitoring strategies for emerging NoV strains.

Abstract
Norovirus is a leading cause of epidemic acute gastroenteritis. More than 30 genotypes circulate in humans, some are common, and others are only sporadically detected. Here, we investigated whether serology can be used to determine which genotypes infect children. We established a multiplex protein microarray with structural and non-structural norovirus antigens that allowed simultaneous antibody testing against 30 human GI and GII genotypes. Antibody responses of sera obtained from 287 children aged < 1 month to 5.5 years were profiled. Most specific IgG and IgA responses were directed against the GII.2, GII.3, GII.4, and GII.6 capsid genotypes. While we detected antibody responses against rare genotypes, we found no evidence for wide circulation. We also detected genotype-specific antibodies against the non-structural proteins p48 and p22 in sera of older children. In this study, we show the age-dependent antibody responses to a broad range of norovirus capsid and polymerase genotypes, which will aid in the development of vaccines.

Abstract
Noroviruses are important etiological agents causing acute intestinal infection in humans. In the last decades, the most common norovirus genotype was GII.4 despite a significant genetic diversity among strains, while the active circulation of noroviruses with other genotypes was observed periodically. This study shows an increase in the detection rate of recombinant GII.3[P12] norovirus in Nizhny Novgorod, Russia, from 6.8% in 2018-2019 to 34.9% in 2020-2021. We performed a phylogenetic analysis based on the nucleotide sequences of noroviruses possessing this genotype obtained in this work, as well as presented in the GenBank database. It has been shown that the circulation of GII.3[P12] noroviruses in the study area was the result of several independent introductions, either directly from the Western Pacific region, or through the Asian part of Russia. The polyphyletic origin, the geographical expansion, and the growth of the epidemic significance of the recombinant GII.3[P12] noroviruses were noted.

Abstract
Background Group A rotavirus (RVA) remains the main causative agent of acute diarrhea among children under five years in countries that have not yet introduced the RVA vaccine worldwide. Long-term and continuous monitoring data on RVA infection in outpatient children were lacking in Shanghai. We investigated the prevalence and distribution of RVA genotypes in outpatient children with acute diarrhea in Shanghai from 2012 to 2018. Methods Stool specimens of outpatient children under five years were collected from the Children’s Hospital of Fudan University in Shanghai, China. All the samples enrolled in this study were detected and characterized for the P and G genotypes of RVA were determined using the semi-multiplex RT-PCR technique. Results Of 1814 children enrolled with acute diarrhea and having specimens collected, 246 (13.6%) were infected with RVA. The highest frequency of RVA was observed in children younger than two years old (87.0%, 214/246). Year-round RVA transmission was observed and the RVA detection rate peaked every winter and troughed in summer. In this study, 12 different RVA strains were identified in children. G9P[8] (49.2%, 121/246) was detected as the most prevalent genotype, followed by G–P[8] (22.8%, 56/246), G3P[8] (11.4%, 28/246), and G9P- (4.9%, 12/246). Although RVA strains detected in this study varied with the time, G9P[8] has been the most predominant circulating genotype since 2012. Furthermore, 12.2% (30/246) RVA positive samples were co-infected with other diarrhea viruses. Conclusion The present analysis showed that RVA was still a major cause of children with acute diarrhea in Shanghai from 2012 to 2018. A great diversity of RVA strains circulated in children with acute diarrhea with G9P[8] being the predominant genotype since 2012. Long-term and continuous monitoring of RVA genotypes is therefore indispensable to refine future vaccine strategy in Shanghai.

Abstract
Background Human noroviruses are the leading cause of sporadic cases and outbreaks of viral acute gastroenteritis in all age groups worldwide. Methods Epidemiological data and fecal specimens were collected between January 2011 and December 2018 from 4911 children < 5 years of age with diarrhea in three districts of Beijing. From 2011 to 2013, One-Step Reverse Transcription Polymerase Chain Reaction (RT-PCR) was used to detect noroviruses, and from January 2014 to December 2018, norovirus GI and GII were screened using duplex quantitative real-time RT-PCR (qRT-PCR). One-Step RT-PCR and RT-seminested PCR were performed to amplify the RNA-dependent polymerase and capsid genes of noroviruses in positive sample. Amplified products were sequenced directly; norovirus was typed using the online Norovirus Genotyping Tool v2.0 and phylogenetic analyses were conducted using MEGA-X. Results From 2011 to 2018, noroviruses were detected in 16.5% of specimens from children with diarrhea. The highest prevalence was observed in children aged 12 to 23 months (22.4%, 319/1421), followed by children aged 6 to 11 months (17.6%, 253/1441). The highest prevalence of norovirus infections occurred in autumn followed by winter, spring, and summer. From 2011 to 2018, the most prevalent dual types (genotype and polymerase type) were GII.4 Sydney[P31] (51.6%, 239/463), followed by GII.3[P12] (24.0%, 111/463), GII.4 2006b[P4 2006b] (7.3%, 34/463), GII.2[P16] (5.0%, 23/463), GII.17[P17] (2.6%, 12/463) and GII.6[P7] (2.6%, 12/463). GII.4 2006b[P4 2006b] predominated in 2011 and 2012. GII.4 Sydney[P31] predominated from 2013 to 2018. In total, 15 genotypes, 15 P-types and 19 dual types were detected in this study, reflecting the genetic diversity. Conclusions There were significant epidemiological characteristics and genetic diversity among outpatient children with norovirus infections < 5 years of age in Beijing from 2011 to 2018. These characteristics differ from those of norovirus outbreaks in Beijing. The complete genome sequences of each genotype are needed to better understand norovirus evolutionary mechanisms.

Abstract
Norovirus (NoV) has been recognized as a leading cause of gastroenteritis worldwide. This review estimates the prevalence and genotype distribution of NoV in China to provide a sound reference for vaccine development. Studies were searched up to October 2020 from CNKI database and inclusion criteria were study duration of at least one calendar year and population size of >100. The mean overall NoV prevalence in individuals with sporadic diarrhea/gastroenteritis was 16.68% (20796/124649, 95% CI 16.63-16.72), and the detection rate of NoV was the highest among children. Non-GII.4 strains have replaced GII.4 as the predominant caused multiple outbreaks since 2014. Especially the recombinant GII.P16-GII.2 increased sharply, and virologic data show that the polymerase GII.P16 rather than VP1 triggers pandemic. Due to genetic diversity and rapid evolution, predominant genotypes might change unexpectedly, which has become major obstacle for the development of effective NoV vaccines.

Abstract
BACKGROUND In addition to rotavirus and norovirus, human adenovirus (HAdV) and classic human astrovirus (classic HAstV) are important pathogens of acute diarrhea in infants and young children. Here, we present the molecular epidemiology of HAdV and classic HAstV in children with acute diarrhea in Shanghai. METHODS Fecal specimens were collected from 804 outpatient infants and young children diagnosed with acute diarrhea in Shanghai from January 2017 to December 2018. All of the samples were screened for the presence of HAdV and classic HAstV. HAdV and classic HAstV were detected using traditional PCR and reverse-transcription PCR, respectively. All of the HAdV and classic HAstV positive samples were genotyped by phylogenetic analysis. RESULTS Among the 804 fecal samples, 8.58% (69/804) of samples were infected with either HAdV or classic HAstV, and five were co-infected with two diarrhea viruses. The overall detection rates of HAdV and classic HAstV were 3.47% (28/804) and 5.22% (42/804), respectively. Four subgroups (A, B, C, and F) and seven genotypes (HAdV-C1, -C2, -B3, -C5, -A31, -F40, and -F41) of HAdV were detected. Subgroup F had the highest constituent ratio at 64.29% (18/28), followed by non-enteric HAdV of subgroup C (21.43%, 6/28) and subgroup B 10.71% (3/28). HAdV-F41 (60.71%, 17/28) was the dominant genotype, followed by HAdV-C2 (14.29%, 4/28) and HAdV-B3 (10.71%, 3/28). Two genotypes of classic HAstV (HAstV-1 and HAstV-5) were identified in 42 samples during the study period; HAstV-1 (95.24%, 40/42) was the predominant genotype, and the other two strains were genotyped as HAstV-5. No significant differences were found between boys and girls in the detection rates of HAdV (P = 0.604) and classic HAstV (P = 0.275). Over half of the HAdV infections (82.14%, 23/28) and classic HAstV infections (66.67%, 28/42) occurred in children less than 36 months. Seasonal preferences of HAdV and classic HAstV infections were summer and winter, respectively. In this study, the common clinical symptoms of children with acute diarrhea were diarrhea, vomiting, fever and abdominal pain. CONCLUSIONS Our findings indicate that HAdV and classic HAstV play important roles in the pathogenesis of acute diarrhea in children in Shanghai. Systematic and long-term surveillance of HAdV and classic HAstV are needed to monitor their prevalence in children and prevent major outbreak.

[PMID: 34039425 PMCID: PMC8149921 DOI: 10.1186/s13099-021-00430-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2021] [Accepted: 05/12/2021] [Indexed: 12/28/2022] Open
Abstract
Objectives Norovirus genotype GII.3[P12] strains have been an important pathogen for sporadic gastroenteritis infection. In previous studies of GII.3[P12], the number of specimens and time span are relatively small, which is difficult to truly reflect the infection and evolution of this type of norovirus. Here we report a molecular epidemiological study of the NoVs prevalent in Jiangsu between 2010 and 2019 to investigate the evolution of the GII.3[P12] strains in China. Methods In this study 60 GII.3[P12] norovirus strains were sequenced and analyzed for evolution, recombination, and selection pressure using bioanalysis software. Results The GII.3[P12] strains were continuously detected during the study period, which showed a high constituent ratio in males, in winter and among children aged 0–11 months, respectively. A time-scaled evolutionary tree showed that both GII.P12 RdRp and GII.3 VP1 sequences were grouped into three major clusters (Cluster I–III). Most GII.3[P12] strains were mainly located in sub-cluster (SC) II of Cluster III. A SimPlot analysis identified GII.3[P12] strain to be as an ORF1-intragenic recombinant of GII.4[P12] and GII.3[P21]. The RdRp genes of the GII.3[P12] showed a higher mean substitution rate than those of all GII.P12, while the VP1 genes of the GII.3[P12] showed a lower mean substitution rate than those of all GII.3. Alignment of the GII.3 capsid sequences revealed that three HBGA binding sites of all known GII.3 strains remained conserved, while several amino acid mutations in the predicted antibody binding sites were detected. The mutation at 385 was within predicted antibody binding regions, close to host attachment factor binding sites. Positive and negative selection sites were estimated. Two common positively selected sites (sites 385 and 406) were located on the surface of the protruding domain. Moreover, an amino acid substitution (aa204) was estimated to be near the active site of the RdRp protein. Conclusions We conducted a comprehensive analysis on the epidemic and evolution of GII.3[P12] noroviruses and the results suggested that evolution was possibly driven by intergenic recombination and mutations in some key amino acid sites.

Global prevalence and genotype distribution of norovirus infection in children with gastroenteritis: A meta-analysis on 6 years of research from 2015 to 2020. Rev Med Virol 2021; 32:e2237. [PMID: 33793023 DOI: 10.1002/rmv.2237] [Citation(s) in RCA: 42] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2021] [Revised: 03/10/2021] [Accepted: 03/15/2021] [Indexed: 12/12/2022]
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.

Epidemiology of norovirus gastroenteritis in hospitalized children under five years old in western China, 2015-2019. JOURNAL OF MICROBIOLOGY, IMMUNOLOGY, AND INFECTION = WEI MIAN YU GAN RAN ZA ZHI 2021; 54:918-925. [PMID: 33531203 DOI: 10.1016/j.jmii.2021.01.002] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 12/30/2020] [Accepted: 01/06/2021] [Indexed: 02/08/2023]
Abstract
OBJECTIVES Norovirus is associated with one-fifth of all gastroenteritis cases, but basic epidemiological data is lacking, especially in developing countries. As long-term surveillance on norovirus gastroenteritis is scarce in western China, this study aims to update the epidemiological knowledge of norovirus gastroenteritis and to characterize the genotypes of norovirus strains. METHODS Stool samples were collected from hospitalized children under 5 years old with gastroenteritis in Chengdu, China. All samples were tested for norovirus as well as rotavirus, sapovirus, enteric adenovirus, and astrovirus by real-time RT-PCR. RdRp and VP1 genes were sequenced in norovirus-positive samples to investigate viral phylogenies. RESULTS Of the 1181 samples collected from 2015 to 2019, 242 (20.5%) were positive for norovirus. Among norovirus-positive cases, 65 cases had co-infection with another virus; norovirus/enteric adenovirus was most frequently detected (50.8%, 33/65). The highest positive rate was observed in children aged 13-18 months (23.7%, 68/287). Norovirus infection peaked in autumn (36.6%, 91/249), followed by summer (20.3%, 70/345). Pearson correlation analysis showed significant correlation between the norovirus-positive rate and humidity (r = 0.773, P < 0.05). GII.4 Sydney 2012 [P31] (48.5%, 79/163) and GII.3 [P12] (35.6%, 58/163) were the dominant norovirus strains. CONCLUSIONS Norovirus has become one of the most common causes of viral gastroenteritis in children under 5 years old in western China. Continuous monitoring is imperative for predicting the emergence of new epidemic strains and for current vaccine development.

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
INTRODUCTION Noroviruses are a leading cause of acute gastroenteritis worldwide. An estimated 21 million illnesses in the United States and upwards of 684 million illnesses worldwide are attributed to norovirus infection. There are no licensed vaccines to prevent norovirus, but several candidates are in development. AREAS COVERED We review recent advances in molecular epidemiology of noroviruses, immunology, and in-vitro cultivation of noroviruses using human intestinal enteroids. We also provide an update on the status of norovirus vaccine candidates. EXPERT OPINION Molecular epidemiological studies confirm the tremendous genetic diversity of noroviruses, the continuous emergence of new recombinant strains, and the predominance of GII.4 viruses worldwide. Duration of immunity, extent of cross protection between different genotypes, and differences in strain distribution for young children compared with adults remain key knowledge gaps. Recent discoveries regarding which epitopes are targeted by neutralizing antibodies using the novel in vitro culture of human noroviruses in human intestinal enteroids are enhancing our understanding of mechanisms of protection and providing guidance for vaccine development. A future norovirus vaccine has the potential to substantially reduce the burden of illnesses due to this ubiquitous virus.
