Article Synopsis
- The COVID-19 pandemic led to significant changes in the occurrence of respiratory syncytial virus (RSV) in Gwangju, South Korea, resulting in no RSV during the 2020/2021 season and a three-fold increase in incidence in the 2021/2022 season, especially in children under 5.
- Whole-genome sequencing of RSV samples pre- and post-pandemic showed shifts in lineages, with only the A.D.3.1 lineage found in the 2021/2022 season, while multiple lineages, including A.D.1 and A.D.3, co-circulated in the following season.
- The study emphasizes the importance of ongoing surveillance to understand
Genomic Analysis and Tracking of SARS-CoV-2 Variants in Gwangju, South Korea, From 2020 to 2022.

Article Synopsis
- - The study analyzes SARS-CoV-2 genetic data from COVID-19 patients in Gwangju, South Korea, from 2020 to 2022 to understand variance trends and infection patterns over time.
- - Key variants identified included B.41, B.1.497, B.1.619.1, and B.1.617.2, with a notable increase in the rapid spread of the Omicron variant after its identification in late December 2021.
- - Findings highlight the importance of regional genomic surveillance alongside national efforts to enhance variant tracking and improve overall infectious disease management.
The non-pharmaceutical interventions implemented to prevent the spread of COVID-19 have affected the epidemiology of other respiratory viruses. In South Korea, Human metapneumovirus (HMPV) typically occurs from winter to the following spring; however, it was not detected for two years during the COVID-19 pandemic and re-emerged in the fall of 2022, which is a non-epidemic season. To examine the molecular genetic characteristics of HMPV before and after the COVID-19 pandemic, we analyzed 427 HMPV-positive samples collected in the Gwangju area from 2018 to 2022.

In the past, evaluation of the enantiomeric ratios of chiral compounds in fruits has been applied as an effective indicator of adulteration by the addition of synthetic compounds or natural components of different botanical origin.
Objective: To analyse the volatile flavour compounds of Citrus junos Sieb.
Tea contains characteristic volatile organic compounds, polyphenols, caffeine and catechins, and is therefore among the most widely consumed beverages all over the world. In this study, fresh Jukro tea leaves collected from Damyang-gun (Jeollanam-do) at 40, 60 and 90day growth stages, were semi-fermented. The volatile organic compounds (VOCs) were extracted by simultaneous distillation-solvent extraction (SDE) and analyzed by gas chromatography/mass spectrometry (GC/MS).
