ABSTRACT

Introduction: There is inadequate information on infections with the Severe Acute Respiratory Syndrome Virus 2 (SARS-CoV-2) in children. Their clinical, as well as pathological correlation, is poorly understood. In India, children and adolescents account for 12% of all Coronavirus Disease 2019 (COVID-19) cases reported. Children accounted for roughly 11% of those impacted globally last year. However, this year, we are seeing around 20-40% of youngsters in positive instances over the world. Even babies and infants are testing positive for COVID-19, although their illness is under control and seldom becomes fatal. Children aged 5 to 12 years, on the other hand, are at a higher risk. Aim: To study the clinical, pathological and genomic characteristics among children with SARS-CoV-2 infection. Materials and Methods: This cross-sectional study was conducted among 48 paediatric positive patients for SARS-CoV-2 at Government Institute of Medical Sciences, Noida, Uttar Pradesh, and CSIR-Institute of Genomics and Integrative Biology, New Delhi, India, from 2021 and May 2021. The laboratory testing was done by the real-time Reverse Transcription-Polymerase Chain Reaction (RT-PCR) method. The patients were classified as mild, moderate, severe, or asymptomatic. Their clinical and pathological findings were recorded in the case sheet. Genomic analyses were done for identifying the genetic variant in the nine selected samples. Data entry and analysis were performed using Statistical Package for Social Sciences (SPSS) version 26.0. Chi-square test was used for categorical variables and the t-test was used for continuous variables. Results: The study group has median age of 12 years. Male:Female ratio was 2:3. Most children had acquired infection from the community and 30% had the moderate illness and were admitted. Serum Glutamic-Oxalacetic Transaminase (SGOT) and Glutamic-Pyruvic Transaminase (SGPT) were raised in six patients. Alkaline Phosphatase (ALP) was raised in 21 patients and bilirubin was raised in two patients. The average duration of hospitalization was 6 days (range 2-13 days). No mortality among the 48 paediatric patients studied was identified in the hospital. Delta variant (B.1.617.2) was identified in seven patients with D614, P681R, L452R mutations and B.1.617.2 was identified in two patients. Delta variant was present in the paediatric patients but it did not prolong the hospital stay or cause mortality. Conclusion: The findings of the study suggest that children may be a potential source of infection in the SARS CoV2 pandemic while having an asymptomatic to mild illness.

ABSTRACT

With the emergence of the Variant of Concern, omicron (B.1.1.529), India has enhanced genomic surveillance in international travellers. The omicron variant was detected in 59 cases from different States;40 from Maharashtra, 17 from Rajasthan and one each from Gujrat and Tamil Nadu. The positive cases and their contacts were asymptomatic and genomic surveillance could identify two clusters, one from Maharashtra and another from Rajasthan.

ABSTRACT

Coronavirus disease (COVID-19) emerged from a city in China and has now spread as a global pandemic affecting millions of individuals. The causative agent, SARS-CoV-2, is being extensively studied in terms of its genetic epidemiology using genomic approaches. Andhra Pradesh is one of the major states of India with the third-largest number of COVID-19 cases with limited understanding of its genetic epidemiology. In this study, we have sequenced 293 SARS-CoV-2 genome isolates from Andhra Pradesh with a mean coverage of 13,324X. We identified 564 high-quality SARS-CoV-2 variants. A total of 18 variants mapped to RT-PCR primer/probe sites, and 4 variants are known to be associated with an increase in infectivity. Phylogenetic analysis of the genomes revealed the circulating SARS-CoV-2 in Andhra Pradesh majorly clustered under the clade A2a (20A, 20B and 20C) (94%), while 6% fall under the I/A3i clade, a clade previously defined to be present in large numbers in India. To the best of our knowledge, this is the most comprehensive genetic epidemiological analysis performed for the state of Andhra Pradesh. © 2021 BMJ Publishing Group. All rights reserved.
