Abstract
Parechovirus A (PeV-A) infections have been detected with increasing frequency in US infants under 6 months of age, leading to a Centers for Disease Control and Prevention (CDC) health advisory in July 2022. Clinicians are advised to consider PeV-A laboratory testing of blood and cerebrospinal fluid when infants present with unexplained fever, sepsis-like illness, or neurological issues. Clinical laboratories are encouraged to offer in-house molecular testing for PeV-A to avoid diagnostic delays, unnecessary use of antibiotics, and prolonged hospitalization of infants presenting with sepsis-like illness. While data are evolving on potential neurodevelopmental sequelae after PeV-A infant central nervous system infections, most infected infants return to baseline health for age. This review examines the PeV-A literature with a focus on PeV-A3, including aspects of epidemiology, clinical presentations/management, laboratory diagnostics, genotyping, and post-infectious sequelae related to PeV-A infections in infants.

Abstract
Human Parechoviruses (HPeVs) have rarely been considered in the virological investigation of Acute Flacid Paralysis (AFP) cases in Africa, where enteric infections are very common. This study investigated the prevalence and genetic diversity of HPeV in 200 children aged ≤ 15 years with AFP in Cameroon from 2018 to 2019. HPeVs were detected in their faecal RNA using 5'-untranslated real-time RT-PCR. Detected HPeVs were typed by phylogenetic comparison with homologous sequences from homotypic reference strains. Overall, HPeV RNA was detected in 11.0% (22/200) of the 200 stool samples tested. Twelve HPeVs were successfully sequenced and reliably assigned to HPeV-A1, A4, A5, A10, A14, A15, A17 and A18 genotypes. Phylogenetic analyses revealed a high genetic variability among the studied HPeVs, as well as between the studied HPeVs and their previously reported counterparts from Cameroon in 2014. These findings suggest that different HPeV genotypes co-circulate in Cameroon without documented epidemics.

Abstract
Human parechovirus A (HPeV-A) is a causative agent of respiratory and gastrointestinal illnesses, acute flaccid paralysis encephalitis, meningitis, and neonatal sepsis. To clarify the characteristics of HPeV-A infection in children, 391 fecal specimens were collected from January 2014 to October 2015 from patients with acute gastroenteritis in Seoul, South Korea. Of these, 221/391 (56.5%) HPeV-A positive samples were found in children less than 2 years old. Three HPeV-A genotypes HPeV-A1 (117/221; 52.94%), HPeV-A3 (100/221; 45.25%), and HPeV-A6 (4/221; 1.81%) were detected, among which HPeV-A3 was predominant with the highest recorded value of 58.6% in 2015. Moreover, recombination events in the Korean HPeV-A3 strains were detected. Phylogenetic analysis revealed that the capsid-encoding regions and noncapsid gene 2A of the four Korean HPeV-A3 strains are closely related to the HPeV-A3 strains isolated in Canada in 2007 (Can82853-01), Japan in 2008 (A308/99), and Taiwan in 2011 (TW-03067-2011) while noncapsid genes P2 (2B-2C) and P3 (3A-3D) are closely related to those of HPeV-A1 strains BNI-788St (Germany in 2008) and TW-71594-2010 (Taiwan in 2010). This first report on the whole-genome analysis of HPeV-A3 in Korea provides insight into the evolving status and pathogenesis of HPeVs in children.

Abstract
Parechovirus A (PeV-A, Parechovirus, Picornaviridae) are human pathogens associated with mild to severe gastrointestinal and respiratory diseases in young children. While several studies have investigated the association of PeV-A with human disease, little is known about its epidemiology or detection in Latin America. Between the years 2014 and 2015, a total of 200 samples were collected from Panamanian pediatric patients aged < 16 years old exhibiting symptoms associated with respiratory (n = 64), gastrointestinal (n = 68), or neurological (n = 68) diseases. These samples were gathered from patients who had previously received negative diagnoses for the main respiratory viruses, rotavirus, and neurological viruses like herpes virus, enterovirus, and cytomegalovirus. The presence of PeV-A was analyzed by real time RT-PCR.Eight positive PeV-A infections (4.0%, 95% CI: 1.7 to 7.7) were detected: two in respiratory samples (3.0%, 95% CI: 0.3 to 10.8), five in gastrointestinal samples (7.3%, 95% CI: 2.4 to 16.3), and one in cerebrospinal fluid (1.5%, 95% CI: 1.4 to 7.9). The study provides evidence of PeV-A circulation in Panama and the data collectively, remarked on the importance of considering PeV-A in the Panamanian pediatric diagnostic landscape, especially when conventional testing for more common viruses yields negative results.

First description and phylogenetic analysis of coxsackie virus A non-polio enteroviruses and parechoviruses A in South Sudanese children. J Med Virol 2023; 95:e29194.

Abstract
Enteroviruses (EV) and parechoviruses A (PeV-A) are commonly circulating viruses able to cause severe disease. Surveillance studies from sub-Saharan Africa are limited and show high but variable infection rates and a high variation in genotypes. This is the first study to describe EV and PeV-A circulation in children in South Sudan. Of the fecal samples collected, 35% and 10% were positive for EV and PeV-A, respectively. A wide range of genotypes were found, including several rarely described EV and PeV-A types. Coxsackie virus A (CVA) EV-C types, particularly CVA13, were the most dominant EV types. The CVA13 types had a high diversity with the majority belonging to four different previously described clusters. PeV-A1 and -A14 were the most common PeV-A genotypes. A lack of representative data from our and other studies from sub-Saharan Africa demonstrates the need for more systematic surveillance of non-polio EV and PeV-A types in this region.

Abstract
Parechovirus-A (PeV-A) causes emerging infection in children, and clinical presentation depends on genotype. The virus has been investigated mainly in developed countries; however, data from developing countries, especially in Asia, are sparse. This study investigated whether PeV-A circulated in children in Myanmar. This retrospective study evaluated PeV-A in nasopharyngeal samples from children aged 1 month to 12 years who were hospitalized with acute lower respiratory infection at Yankin Children Hospital, Yangon, Myanmar, during the period from May 2017 to April 2019. Real-time polymerase chain reaction (PCR) was used to detect PeV-A, and PCR-positive samples were used for genotyping and phylogenetic analysis. In total, 11/570 (1.9%) of samples were positive for PeV-A; 7 were successfully genotyped by sequencing the VP3/VP1 region, as follows: PeV-A1 (n = 4), PeV-A5 (n = 1), PeV-A6 (n = 1), and PeV-A14 (n = 1). Median age was 10.0 months (interquartile range 4.0-12.0 months), and other respiratory viruses were detected in all cases. Phylogenetic analysis showed that all detected PeV-A1 strains were in clade 1 A, which was a minor clade worldwide. Four PeV-A genotypes were detected in Myanmar. The clinical impact of PeV-A in children should be evaluated in future studies.

Abstract
We analyzed the prevalence and genotypes of Parechovirus A (PeV-A) in children with diarrhea in Beijing, China, 2017-2019. A total of 1734 stool samples collected from children <5 years of age with diarrhea were tested for the presence of PeV-A. Viral RNA was detected by real-time RT-PCR, and then genotyped by nested RT-PCR. We detected PeV-A in 93 (5.4%, 93/1734) samples, of which 87 could be genotyped by amplification of either the complete or partial VP1 region or the VP3/VP1 junction region. The median age of PeV-A infected children was 10 months. Most PeV-A infections were observed between August and November, with a peak in September. Seven known genotypes of PeV-A1A, -A1B, -A3, -A4, -A6, -A8 and -A11 were detected and PeV-A1B was the most prevalent genotype. Coinfection with other diarrheal viruses was observed in 30.1% (28/93) of PeV-A positive samples. All strains of PeV-A1A, -A1B, -A4 and -A6 obtained in this study contained the arginine-glycine-aspartic (RGD) motif, while all strains of PeV-A3, -A8 and -A11 lacked it. This study revealed a high genetic diversity of PeV-A circulating in Beijing and PeV-A11 was reported for the first time in children with diarrhea in China.

Abstract
Using a metagenomic sequencing approach, we described and compared the diversity and dynamics of the oropharyngeal and fecal eukaryotic virome of nine asymptomatic children in a semi-rural community setting located in the State of Morelos, Mexico. Ninety oropharyngeal swabs and 97 fecal samples were collected starting 2 weeks after birth and monthly thereafter until 12 months of age. In both niches, more than 95% of the total sequence reads were represented by viruses that replicate either in humans or in plants. Regarding human viruses, three families were most abundant and frequent in the oropharynx: Herpesviridae, Picornaviridae, and Reoviridae; in fecal samples, four virus families predominated: Caliciviridae, Picornaviridae, Reoviridae, and Anelloviridae. Both niches showed a high abundance of plant viruses of the family Virgaviridae. Differences in the frequency and abundance of sequence reads and diversity of virus species were observed in both niches and throughout the year of study, with some viruses already present in the first months of life. Our results suggest that the children's virome is dynamic and likely shaped by the environment, feeding, and age. Moreover, composition analysis suggests that the virome composition is mostly individual. Whether this constant exposition to different viruses has a long-term impact on children's health or development remains to be studied.

Abstract
Human parechoviruses (HPeVs) are important causes of infection in children. However, without a comprehensive and persistent surveillance, the epidemiology and clinical features of HPeV infection remain ambiguous. We performed a hospital-based surveillance study among three groups of pediatric patients with acute respiratory infection (Group 1), acute diarrhea (Group 2), and hand, foot and mouth disease (Group 3) in Chongqing, China, from 2009 to 2015. Among 10,212 tested patients, 707 (6.92%) were positive for HPeV, with the positive rates differing significantly among three groups (Group 1, 3.43%; Group 2, 14.94%; Group 3, 3.55%; P < 0.001). The co-infection with other pathogens was detected in 75.2% (531/707) of HPeV-positive patients. Significant negative interaction between HPeV and Parainfluenza virus (PIV) (P = 0.046, OR = 0.59, 95% CI = 0.34–0.98) and positive interactions between HPeV and Enterovirus (EV) (P = 0.015, OR = 2.28, 95% CI = 1.23–4.73) were identified. Among 707 HPeV-positive patients, 592 (83.73%) were successfully sequenced, and 10 genotypes were identified, with HPeV1 (n = 396), HPeV4 (n = 86), and HPeV3 (n = 46) as the most frequently seen. The proportion of genotypes differed among three groups (P < 0.001), with HPeV1 and HPeV4 overrepresented in Group 2 and HPeV6 overrepresented in Group 3. The spatial patterns of HPeV genotypes disclosed more close clustering of the currently sequenced strains than those from other countries/regions, although they were indeed mixed. Three main genotypes (HPeV1, HPeV3, and HPeV4) had shown distinct seasonal peaks, highlighting a bi-annual cycle of all HpeV and two genotypes (HPeV 1 and HPeV 4) with peaks in odd-numbered years and with peaks in even-numbered years HPeV3. Significantly higher HPeV1 viral loads were associated with severe diarrhea in Group 2 (P = 0.044), while associated with HPeV single infection than HPeV-EV coinfection among HFMD patients (P = 0.001). It’s concluded that HPeV infection was correlated with wide clinical spectrum in pediatric patients with a high variety of genotypes determined. Still no clinical significance can be confirmed, which warranted more molecular surveillance in the future.

J Virol Methods 2021; 293:114167. [PMID: 33894205 DOI: 10.1016/j.jviromet.2021.114167] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2020] [Revised: 03/17/2021] [Accepted: 04/15/2021] [Indexed: 10/21/2022]
Abstract
Parechoviruses (PeVs) are common viruses that cause mild gastrointestinal or respiratory symptoms to severe central nervous system infections. In infants, parechovirus infection is one of the leading causes of life-threatening viral disease. High-quality antibodies with broad binding specificities are essential to improve accurate parechovirus diagnosis in diagnostic laboratories. Such antibodies have potential in the development of rapid antigen detection assay against PeVs. In the present study, VP4 and VP2 genes from human parechovirus A1 (PeV-A1) were cloned and VP0 fusion protein produced to develop monoclonal antibodies against PeVs. Two pan-parechovirus antibodies, one IgG and one IgM isotype, were isolated. The properties of IgG1/κ monoclonal (designated as Mab-PAR-1) was studied further. Mab-PAR-1 was shown to be functional in western blot against denatured recombinant protein and viral particles. In immunofluorescence assay, the antibody tested positive for nineteen PeV-A1 isolates while showing no cross-reactivity to fourteen entero- and rhinovirus types. In addition, Mab-PAR-1 showed positive reactivity against five other cultivable parechovirus types 2-6. A unique Mab-PAR-1 epitope located in the junction of the three capsid proteins VP0, VP1, and VP3 was identified using a peptide library screen. This study demonstrates that PeV-A1-VP0 protein is functional antigen for developing monoclonal antibody for diagnosis of broad range of parechovirus infections.

Abstract
Human parechoviruses (HPeVs) are human pathogens that usually cause diseases ranging from rash to neonatal sepsis in young children. HPeV1 and HPeV3 are the most frequently reported genotypes and their three-dimensional structures have been determined. However, there is a lack of systematic research on the antigenic epitopes of HPeVs, which are useful for understanding virus-receptor interactions, developing antiviral agents or molecular diagnostic tools, and monitoring antigenic evolution. Thus, we systematically predicted and compared the conformational epitopes of HPeV1 and HPeV3 using bioinformatics methods in the study. The results showed that both epitopes clustered into three sites (sites 1, 2 and 3). Site 1 was located on the "northern rim" near the fivefold vertex; site 2 was on the "puff"; and site 3 was divided into two parts, of which one was located on the "knob" and the other was close to the threefold vertex. The predicted epitopes highly overlapped with the reported antigenic epitopes, which indicated that the prediction results were accurate. Although the distribution positions of the epitopes of HPeV1 and HPeV3 were highly consistent, the residues varied largely and determined the genotypes. Three amino acid residues, VP3-91N, -92H and VP0-257S, were the key residues for monoclonal antibody (mAb) AM28 binding to HPeV1 and were also of great significance in distinguishing HPeV1 and HPeV3. We also found that two residues, VP1-85N and -87D, might affect the capability of mAb AT12-015 to bind to HPeV3.

Abstract
Parechovirus A (PeV-A), previously known as human parechovirus, is a common pathogen in children that can cause respiratory and gastrointestinal diseases as well as severe neurological disease. Take advantage of our previous findings on the genetic diversity of PeV-A circulating in Japanese children with acute gastroenteritis (AGE), this study was conducted to investigate the genetic diversity of PeV-A isolated from children with AGE in Japan as well as their clinical symptoms. Of 1070 stool samples collected from Japanese infants and children with AGE during the 2-year period from July 2016 to June 2018, 76 were positive for PeV-A by multiplex reverse transcriptase-polymerase chain reaction (RT-PCR) and were subjected to genotyping based on viral protein 1 (VP1) sequences. Five different PeV-A genotypes including PeV-A1B, -A2, -A3, -A4, and -A6 were detected with predominant of PeV-A1 clade B genotype. This study revealed a high genetic diversity of PeV-A circulating in Japanese infants and children with AGE and the PeV-A2, a rare genotype, was detected for the first time in Japan in patients with AGE. The clinical symptoms observed in these patients included diarrhea, vomiting, fever, cough, rhinorrhea, and dehydration.

Abstract
Parechoviruses are emerging pathogens of humans often affecting the pediatric age group, with a growing line of evidence implicating them as agents of a broad spectrum of clinical syndromes in adults. However, because many clinicians are not familiar with the manifestation of the infections, they are not included in the list of diagnostic pathogens. Furthermore, due to the indistinguishable feature of the infection compared with other common pathogens, a large number of cases are likely to go unchecked. Some may develop asymptomatic infection and recover without overt clinical disease. In this manuscript, we reviewed available literature on parechovirus infection in adult and summarized information relating to epidemiology, clinical manifestation, laboratory diagnosis, and therapeutics. The information provided should help in early case detection and support an evidence-based clinical decision.

Abstract
Using a metagenomics approach, we have determined the first full-length genome sequence of a human parechovirus type 15 (HPeV15) strain, isolated from a child with acute flaccid paralysis and co-infected with EV-A71. HPeV15 is a rarely reported type. To date, no full-length genome sequence of HPeV15 is available in the GenBank database, where only limited VP1 sequences of this virus are available. Pairwise comparisons of the complete VP1 nucleotide and deduced amino acid sequences revealed that the study strain belongs to type 15 as it displayed 79.6% nucleotide and 93.4% amino acid identity with the HPeV15 prototype strain. Comparative analysis of available genomic regions and phylogenetic analysis using the P2 and P3 coding regions revealed low nucleotide identity to HPeV reference genomes. Phylogenetic and similarity plot analyses showed that genomic recombination events might have occurred in the UTRs and nonstructural region during HPeV15 evolution. The study strain has high similarity features with different variants of HPeV3 suggesting intertypic recombination. Our data contributes to the scarce data available on HPeVs in Africa and provides valuable information for future studies that aim to understand the evolutionary history, molecular epidemiology or biological and pathogenic properties of HPeV15.
