Investigation of SARS-CoV-2 lineages and mutations circulating in a university-affiliated hospital in South Korea analyzed using Oxford Nanopore MinION sequencing
Publication Type: Academic Journal
Source(s): Osong Public Health and Research Perspectives, Vol 13, Iss 5, Pp 360-369 (2022)
Abstract: Objectives Despite the introduction of vaccines, treatments, and massive diagnostic testing, the evolution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has continued to overcome barriers that had slowed its previous spread. As the vi...
The SARS-CoV-2 Delta (B.1.617.2) variant with spike N501Y mutation in the shadow of Omicron emergence
Publication Type: Academic Journal
Source(s): Heliyon, Vol 8, Iss 12, Pp e12650- (2022)
Abstract: Circulation of the Omicron variant with the reemergence of the N501Y mutation along with many others in the spike protein has once again stirred the academic community. Interestingly, tracing the genetic diversity of SARS-CoV-2 shed light on a less fre...
Reduction of the risk of severe COVID-19 due to Omicron compared to Delta variant in Italy (November 2021 – February 2022)
Publication Type: Academic Journal
Source(s): International Journal of Infectious Diseases, Vol 129, Iss , Pp 135-141 (2023)
Abstract: Objectives: During 2022, Omicron became the dominant SARS-CoV-2 variant in Europe. This study aims to assess the impact of such variant on severe disease from SARS-CoV-2 compared with the Delta variant in Italy. Methods: Using surveillance data, we ass...
Prevalence and associating factors of long COVID in pediatric patients during the Delta and the Omicron variants
Publication Type: Academic Journal
Source(s): Frontiers in Pediatrics, Vol 11 (2023)
Abstract: IntroductionThe number of pediatric COVID-19 infections is increasing; however, the data on long COVID conditions in children is still limited. Our study aimed to find the prevalence of long COVID in children during the Delta and Omicron waves, as well...
Post COVID-19 condition after delta infection and omicron reinfection in children and adolescentsResearch in context
