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...
Characteristics and outcomes of vaccinated and nonvaccinated patients hospitalized in a single Italian hub for COVID-19 during the Delta and Omicron waves in Northern Italy
Publication Type: Academic Journal
Source(s): International Journal of Infectious Diseases, Vol 122, Iss , Pp 420-426 (2022)
Abstract: Objective: We compared the characteristics and outcomes of vaccinated and nonvaccinated patients hospitalized with COVID-19. Design: We analyzed patients hospitalized in a COVID hub during three one-month periods: (i) October 15, 2020-November 15, 2020...
Post COVID-19 condition after delta infection and omicron reinfection in children and adolescentsResearch in context
Publication Type: Academic Journal
Source(s): EBioMedicine, Vol 92, Iss , Pp 104599- (2023)
Abstract: Summary: Background: The burden of COVID-19 in children and adolescents has increased during the delta and omicron waves, necessitating studies of long-term symptoms such as fatigue, dyspnoea and cognitive problems. Furthermore, immune responses in rel...
Simultaneous co-infection with Omicron (B.1.1.529) and Delta (21A/478K.V1) SARS-CoV-2 variants confirmed by whole genome sequencing
Publication Type: Academic Journal

Adsorption of SARS CoV-2 spike proteins on various functionalized surfaces correlates with the high transmissibility of Delta and Omicron variants
Publication Type: Academic Journal
Source(s): Materials Today Bio, Vol 14, Iss , Pp 100265- (2022)
Abstract: The SARS-CoV-2 virus emerged at the end of 2019 and rapidly developed several mutated variants, specifically the Delta and Omicron, which demonstrate higher transmissibility and escalating infection cases worldwide. The dominant transmission pathway of...
