Respiratory syncytial virus (RSV) causes acute lower respiratory tract infection in infants and young children worldwide. To investigate the RSV burden in Thailand over four consecutive years (January 2012 to December 2015), we screened 3,306 samples obtained from children ≤5 years old with acute respiratory tract infection using semi-nested reverse-transcription polymerase chain reaction (RT-PCR). In all, 8.4% (277/3,306) of the specimens tested positive for RSV, most of which appeared in the rainy months of July to November. We then genotyped RSV by sequencing the G glycoprotein gene and performed phylogenetic analysis to determine the RSV antigenic subgroup. The majority (57.4%, 159/277) of the RSV belonged to subgroup A (RSV-A), of which NA1 genotype was the most common in 2012 while ON1 genotype became prevalent the following year. Among samples tested positive for RSV-B subgroup B (RSV-B) (42.6%, 118/277), most were genotype BA9 (92.6%, 87/94) with some BA10 and BA-C. Predicted amino acid sequence from the partial G region showed highly conserved N-linked glycosylation site at residue N237 among all RSV-A ON1 strains (68/68), and at residues N296 (86/87) and N310 (87/87) among RSV-B BA9 strains. Positive selection of key residues combined with notable sequence variations on the G gene contributed to the continued circulation of this rapidly evolving virus.

Background: Acute respiratory tract infection are a major cause of global morbidity and mortality. Observational studies report consistent independent association between low serum concentration of 25-hydroxy-vitamin D and susceptibility to acute respiratory tract infection. This study was done to assess serum vitamin D level in children and correlation with respiratory tract infection.Methods: The present study was undertaken in department of paediatrics medicine, Patna Medical College and Hospital in patients attending out-patients department (OPD) as well as admitted in in-patients department (IPD). Assessment of serum 25(OH) Vitamin D was done by the enzyme immunoassay kit at Patna Medical College and Hospital.Results: The mean serum vitamin D level in cases was (20.52±5.64 ng/ml) where as in control group was (26.46±4.52 ng/ml) with a statically significant p value of <0.0001, hence cases are associated with vitamin D deficiency.Conclusions: The finding in this study showed significantly decreased mean serum vitamin D level in cases than that of control which implies that vitamin D deficiency predisposes to respiratory tract infection in children.

Human enterovirus 68 (HEV-68) is an enterovirus associated with respiratory illness. In China, no information about HEV-68 is available for children yet. This study aimed to investigate the presence of HEV-68 in mainland China between 2009 and 2012 and to explore the migration events of HEV-68 across the world. Among 1565 samples tested from children, 41 (2.6 %) were positive for HEV and 223 (14.3 %) for human rhinovirus (HRV). Seven (17.1 %) of 41 HEVs were HEV-68. Two HEV-68- and five HRV-positive samples were detected in 585 adult samples. HEV-68 is the predominant type of enterovirus in children with acute respiratory tract infection (ARTI), followed by HEV-71 and coxsackievirus A6. Three HEV-68-infected children presented with severe pneumonia and one presented with a severe asthma attack. The viruses were attributed to two novel distinct sublineages of HEV-68 based on phylogenetic analysis of partial VP1 gene sequences. Migration events analysis showed that the USA and the Netherlands were possible geographical sources of HEV-68, from where three strains migrated to China. In conclusion, HEV-68 may play a predominant role among the enteroviruses associated with ARTI in children. Additional surveillance is needed to clarify the reason why HEV-68 causes such a wide spectrum of disease, from asymptomatic to severe respiratory disease and even death.
