Complete Genome Sequences of Five Human Coronavirus NL63 Strains Causing Respiratory Illness in Hospitalized Children in China.

ABSTRACT: We report the complete genome sequences of five human coronavirus NL63 (HCoV-NL63) strains obtained using next-generation sequencing. The five HCoV-NL63 strains were obtained from hospitalized children with severe acute respiratory infection detected in Guangdong, China. This study provides several complete genomes of HCoV-NL63 and improves our understanding of HCoV-NL63 evolution in China.

Human coronavirus NL63 infection and other coronavirus infections in children hospitalized with acute respiratory disease in Hong Kong, China.

Project description:BackgroundHuman coronavirus NL63 (HCoV-NL63) is a recently discovered human coronavirus found to cause respiratory illness in children and adults that is distinct from the severe acute respiratory syndrome (SARS) coronavirus and human coronaviruses 229E (HCoV-229E) and OC43 (HCoV-OC43).MethodsWe investigated the role that HCoV-NL63, HCoV-OC43, and HCoV-229E played in children hospitalized with fever and acute respiratory symptoms in Hong Kong during the period from August 2001 through August 2002.ResultsCoronavirus infections were detected in 26 (4.4%) of 587 children studied; 15 (2.6%) were positive for HCoV-NL63, 9 (1.5%) were positive for HCoV-OC43, and 2 (0.3%) were positive for HCoV-229E. In addition to causing upper respiratory disease, we found that HCoV-NL63 can present as croup, asthma exacerbation, febrile seizures, and high fever. The mean age (+/- standard deviation [SD]) of the infected children was 30.7 +/- 19.8 months (range, 6-57 months). The mean maximum temperature (+/- SD) for the 12 children who were febrile was 39.3 degrees C +/- 0.9 degrees C, and the mean total duration of fever (+/- SD) for all children was 2.6 +/- 1.2 days (range, 1-5 days). HCoV-NL63 infections were noted in the spring and summer months of 2002, whereas HCoV-OC43 infection mainly occurred in the fall and winter months of 2001. HCoV-NL63 viruses appeared to cluster into 2 evolutionary lineages, and viruses from both lineages cocirculated in the same season.ConclusionsHCoV-NL63 is a significant pathogen that contributes to the hospitalization of children, and it was estimated to have caused 224 hospital admissions per 100,000 population aged < or = 6 years each year in Hong Kong.

Genome Sequences of Human Coronavirus OC43 and NL63, Associated with Respiratory Infections in Kilifi, Kenya.

Project description:Coding-complete genomes of two human coronavirus OC43 strains and one NL63 strain were obtained by metagenomic sequencing of clinical samples collected in 2017 and 2018 in Kilifi, Kenya. Maximum likelihood phylogenies showed that the OC43 strains were genetically dissimilar and that the NL63 strain was closely related to NL63 genotype B viruses.

Human coronavirus in young children hospitalized for acute respiratory illness and asymptomatic controls.

Project description:Human coronaviruses (HCoVs) have been detected in children with upper and lower respiratory symptoms, but little is known about their relationship with severe respiratory illness.To compare the prevalence of HCoV species among children hospitalized for acute respiratory illness and/or fever (ARI/fever) with that among asymptomatic controls and to assess the severity of outcomes among hospitalized children with HCoV infection compared with other respiratory viruses.From December 2003 to April 2004 and October 2004 to April 2005, we conducted prospective, population-based surveillance of children <5 years of age hospitalized for ARI/fever in 3 US counties. Asymptomatic outpatient controls were enrolled concurrently. Nasal/throat swabs were tested for HCoV species HKU1, NL63, 229E, and OC43 by real-time reverse-transcription polymerase chain reaction. Specimens from hospitalized children were also tested for other common respiratory viruses. Demographic and medical data were collected by parent/guardian interview and medical chart review.Overall, HCoV was detected in 113 (7.6%) of 1481 hospitalized children (83 [5.7%] after excluding 30 cases coinfected with other viruses) and 53 (7.1%) of 742 controls. The prevalence of HCoV or individual species was not significantly higher among hospitalized children than controls. Hospitalized children testing positive for HCoV alone tended to be less ill than those infected with other viruses, whereas those coinfected with HCoV and other viruses were clinically similar to those infected with other viruses alone.In this study of children hospitalized for ARI/fever, HCoV infection was not associated with hospitalization or with increased severity of illness.

Closed Complete Annotated Genome Sequences of Five Haemophilus influenzae Biogroup aegyptius Strains.

Project description:Haemophilus influenzae biogroup aegyptius is a cause of conjunctivitis in children. Biogroup aegyptius strains also caused fatal outbreaks of invasive disease, known as Brazilian purpuric fever (BPF), in the 1980s. BPF is fatal if untreated. Here, we report the complete genome sequences of five strains of Haemophilus influenzae biogroup aegyptius.

A novel pancoronavirus RT-PCR assay: frequent detection of human coronavirus NL63 in children hospitalized with respiratory tract infections in Belgium.

Project description:BackgroundFour human coronaviruses are currently known to infect the respiratory tract: human coronaviruses OC43 (HCoV-OC43) and 229E (HCoV-229E), SARS associated coronavirus (SARS-CoV) and the recently identified human coronavirus NL63 (HCoV-NL63). In this study we explored the incidence of HCoV-NL63 infection in children diagnosed with respiratory tract infections in Belgium.MethodsSamples from children hospitalized with respiratory diseases during the winter seasons of 2003 and 2004 were evaluated for the presence of HCoV-NL63 using a optimized pancoronavirus RT-PCR assay.ResultsSeven HCoV-NL63 positive samples were identified, six were collected during January/February 2003 and one at the end of February 2004.ConclusionsOur results support the notation that HCoV-NL63 can cause serious respiratory symptoms in children. Sequence analysis of the S gene showed that our isolates could be classified into two subtypes corresponding to the two prototype HCoV-NL63 sequences isolated in The Netherlands in 1988 and 2003, indicating that these two subtypes may currently be cocirculating.
