Abstract
Echovirus 9 (E9) belongs to the species Enterovirus B. So far, 12 whole genome sequences of E9 are available in GenBank. In this study, we determined the whole genomic sequences of five E9 strains isolated from the stools of patients with hand-foot-and-mouth disease in Kunming, Yunnan Province, China, in 2019. Their nucleotide and amino acid sequences shared 80.8–80.9% and 96.4–96.8% identity with the prototype Hill strain, respectively, and shared 99.3–99.9% and 99.1–99.8% mutual identity, respectively. Recombination analyses revealed that intertype recombination had occurred in the 2C and 3D regions of the five Yunnan E9 strains with coxsackieviruses B5 and B4, respectively. This study augmented the whole genome sequences of E9 in the GenBank database and extended the molecular characterization of this virus in China.

Abstract
In humans, several respiratory viruses can have neurologic implications affecting both central and peripheral nervous system. Neurologic manifestations can be linked to viral neurotropism and/or indirect effects of the infection due to endothelitis with vascular damage and ischemia, hypercoagulation state with thrombosis and hemorrhages, systemic inflammatory response, autoimmune reactions, and other damages. Among these respiratory viruses, recent and huge attention has been given to the coronaviruses, especially the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic started in 2020. Besides the common respiratory symptoms and the lung tropism of SARS-CoV-2 (COVID-19), neurologic manifestations are not rare and often present in the severe forms of the infection. The most common acute and subacute symptoms and signs include headache, fatigue, myalgia, anosmia, ageusia, sleep disturbances, whereas clinical syndromes include mainly encephalopathy, ischemic stroke, seizures, and autoimmune peripheral neuropathies. Although the pathogenetic mechanisms of COVID-19 in the various acute neurologic manifestations are partially understood, little is known about long-term consequences of the infection. These consequences concern both the so-called long-COVID (characterized by the persistence of neurological manifestations after the resolution of the acute viral phase), and the onset of new neurological symptoms that may be linked to the previous infection.

Abstract
HISTORY A 35-year-old, previously healthy woman presented with short history of headache and fever. Several other family members reported active hand, foot, and mouth disease. FINDINGS Clinical findings showed subfebrile temperatures and a prominent meningism. Cerebrospinal fluid and computed tomography of the head were unrevealing. Subsequent PCR-analysis of the cerebrospinal fluid was positive for Enteroviral-RNA. DIAGNOSIS AND THERAPY Enteroviral-meningitis was diagnosed. The empirically administered antimicrobial therapy was stopped and further diagnostic tests could be withheld. COURSE Symptom-oriented therapy resulted in complete resolution within the next few days. CONCLUSIONS Our case emphasizes that, in patients with typical signs of meningeal irritation, normal cellular analysis of the cerebrospinal fluid does not exclude the presence of infectious meningitis. The astute clinician should be reminded that this constellation is highly suggestive of enteroviral meningitis.

Analysis of enterovirus genotypes in the cerebrospinal fluid of children associated with aseptic meningitis in Liaocheng, China, from 2018 to 2019. BMC Infect Dis 2021; 21:405. [PMID: 33933008 PMCID: PMC8088645 DOI: 10.1186/s12879-021-06112-9] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Accepted: 04/23/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Aseptic meningitis is most often caused by enteroviruses (EVs), but EVs associated with aseptic meningitis have not yet been reported in Liaocheng. The aim of this study was to determine the prevalence and genetic characteristics of EVs causing aseptic meningitis in children in Liaocheng. METHODS We reviewed the epidemiological and clinical characteristics of 504 paediatric cases of aseptic meningitis in Liaocheng from 2018 to 2019 and analysed the phylogeny of the predominant EV types causing this disease. RESULTS A total of 107 children were positive for EV in cerebrospinal fluid samples by nested PCR. Most of the positive patients were children 13 years old or younger and had symptoms such as fever, headache and vomiting (P < 0.05). The seasons with the highest prevalence of EV-positive cases were summer and autumn. The 107 EV sequences belonged to 8 serotypes, and echovirus types 18, 6 and 11 were the three dominant serotypes in Liaocheng during the 2-year study period. Phylogenetic analyses demonstrated that the E18 and E6 isolates belonged to subgenotype C2, while the E11 isolates belonged to subgenotype D5. VP1 analysis suggested that only one lineage of these three types was cocirculating in the Liaocheng region. CONCLUSIONS This study demonstrated the diverse EV genotypes contributing to a large outbreak of aseptic meningitis in Liaocheng. Therefore, large-scale surveillance is required to assess the epidemiology of EVs associated with aseptic meningitis and is important for the diagnosis and treatment of aseptic meningitis in Liaocheng.

J Pediatric Infect Dis Soc 2021; 10:398-407. [PMID: 33150450 DOI: 10.1093/jpids/piaa111] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2020] [Accepted: 09/01/2020] [Indexed: 01/07/2023]
Abstract
BACKGROUND Enteroviruses (EVs) occur frequently worldwide and are known to be associated with a broad spectrum of clinical manifestations from mild syndromes to neurological disease. To understand the epidemiology of EV in Korea, we characterized EV-infected cases during 2012-2019 based on national surveillance. METHODS We collected specimens from patients with suspected EV infections and analyzed the data using real-time reverse-transcription polymerase chain reaction and VP1 gene sequencing. RESULTS Among the 18 261 specimens collected, EVs were detected in 6258 (34.3%) cases. Although the most common EV types changed annually, EV-A71, echovirus 30, coxsackievirus B5, coxsackievirus A6, and coxsackievirus A10 were commonly identified. Among the human EVs, the case numbers associated with the 2 major epidemic species (EV-A and EV-B) peaked in the summer. While EV-A species affected 1-year-old children and were associated with herpangina and hand, foot, and mouth disease, EV-B species were mostly associated with neurologic manifestations. The highest incidence of EV-B species was observed in infants aged <12 months. Feces and respiratory specimens were the most predictive of EV infection. Specimens collected within 5 days of symptom onset allowed for timely virus detection. CONCLUSIONS EV-A and EV-B species co-circulating in Korea presented different epidemiologic trends in clinical presentation, affected subjects, and seasonality trends. This study could provide information for the characterization of EVs circulating in Korea to aid the development of EV antivirals and vaccines, as well as public health measures to control enteroviral diseases.

Abstract
Limited recent molecular epidemiology data are available for pediatric Central Nervous System (CNS) infections in Europe. The aim of this study was to investigate the molecular epidemiology of enterovirus (EV) involved in CNS infections in children. Cerebrospinal fluid (CSF) from children (0–16 years) with suspected meningitis–encephalitis (ME) who were hospitalized in the largest pediatric hospital of Greece from October 2017 to September 2020 was initially tested for 14 common pathogens using the multiplex PCR FilmArray® ME Panel (FA-ME). CSF samples positive for EV, as well as pharyngeal swabs and stools of the same children, were further genotyped employing Sanger sequencing. Of the 330 children tested with FA-ME, 75 (22.7%) were positive for EV and 50 different CSF samples were available for genotyping. The median age of children with EV CNS infection was 2 months (IQR: 1–60) and 44/75 (58.7%) of them were male. There was a seasonal distribution of EV CNS infections, with most cases detected between June and September (38/75, 50.7%). EV genotyping was successfully processed in 84/104 samples: CSF (n = 45/50), pharyngeal swabs (n = 15/29) and stools (n = 24/25). Predominant EV genotypes were CV-B5 (16/45, 35.6%), E30 (10/45, 22.2%), E16 (6/45, 13.3%) and E11 (5/45, 11.1%). However, significant phylogenetic differences from previous described isolates were detected. No unusual neurologic manifestations were observed, and all children recovered without obvious acute sequelae. Specific EV circulating genotypes are causing a significant number of pediatric CNS infections. Phylogenetic analysis of these predominant genotypes found genetic differences from already described EV isolates.

Clinical characteristics of echovirus 11 and coxsackievirus B5 infections in Taiwanese children requiring hospitalization. JOURNAL OF MICROBIOLOGY, IMMUNOLOGY, AND INFECTION = WEI MIAN YU GAN RAN ZA ZHI 2020; 54:581-587. [PMID: 32653431 DOI: 10.1016/j.jmii.2020.06.008] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/18/2020] [Revised: 05/29/2020] [Accepted: 06/24/2020] [Indexed: 11/21/2022]
Abstract
BACKGROUND Severe illness can occur in young children infected with certain types of enteroviruses including echovirus 11 (Echo11) and coxsackievirus B5 (CoxB5). The manifestations and outcomes of Echo11 and CoxB5 diseases across all ages of children remained not comprehensively characterized in Taiwan. METHODS Culture-confirmed Echo11 (60 patients) or CoxB5 (65 patients) infections were identified in a hospital from 2010 to 2018. The demographics, clinical presentations, laboratory data and outcomes were abstracted and compared between the two viruses infections. RESULTS Echo11 and CoxB5 was respectively identified in 7 (77.8%) and 2 (22.2%) of 9 calendar years. The median age of all patients was 15 months (range, 1 day-14.5 years). For infants ≤3 months old, Echo11 (23 cases) was associated with higher incidence of aseptic meningitis (35% versus 0%, P = 0.003), and a lower rate of upper respiratory tract infections (URI) (22% versus 65%, P = 0.004) compared to CoxB5 (20 cases) infections. For patients >3 months old, URI was the cardinal diagnosis (60%) for both viruses. Aseptic meningitis was also more commonly identified in elder children with Echo11 infections (27% versus 11%), though with marginal significance (P = 0.07). Acute liver failure was identified in four young infants with Echo11 infections including one neonate dying of severe sepsis and myocarditis. All patients with CoxB5 infections recovered uneventfully. CONCLUSION Aseptic meningitis, sepsis-like illness and acute liver failure were more commonly identified in children with Echo11 than those with CoxB5 infections, suggesting greater neurological tropism and virulence toward Echo11.
