Abstract:
Multiple new SARS-CoV-2 variants of concern (VOC) have emerged globally since the onset of the COVID-19 pandemic. With the virus continuing to evolve, more are expected. This emphasizes the need for rapid diagnostic methods for the detection of circulating lineages. Variants-specific real-time reverse transcription (rRT)-PCR method can be used as an alternative to genome sequencing, which is expensive and labored for identifying these variants, especially in settings with limited resources. We assessed the prevalence of various SARS-CoV-2 variants spreading in the Erbil province using a diagno

Abstract:
Over the past two years, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused hundreds of millions of infections, resulting in an unprecedented pandemic of coronavirus disease 2019 (COVID-19). As the virus spreads through the population, ongoing mutations and adaptations are being discovered. There is now substantial clinical evidence that demonstrates the SARS-CoV-2 variants have stronger transmissibility and higher virulence compared to the wild-type strain of SARS-CoV-2. Hence, development of vaccines against SARS-CoV-2 variants to boost individual immunity has become

Abstract:
The evolutionary dynamics of viruses, particularly exemplified by SARS-CoV-2 during the ongoing COVID-19 pandemic, underscore the intricate interplay between genetics, host adaptation, and viral spread. This paper delves into the genetic evolution of SARS-CoV-2, emphasizing the implications of viral variants on global health. Initially emerging from the Wuhan-Hu-1 lineage, SARS-CoV-2 rapidly diversified into numerous variants, each characterized by distinct mutations in the spike protein and other genomic regions. Notable variants such as B.1.1.7 (α), B.1.351 (β), P.1 (γ), B.1.617.2 (δ), and t

Abstract:
Since the outbreak of novel coronavirus pneumonia in Wuhan in 2019, the SARS-CoV-2 epidemic has become a hot topic. Over time, SARS-CoV-2 has evolved many variants. The diversity of the 3-D structure of the variant’s proteins resulted in the difference in the binding ability and infectious differences between different virus variants and human angiotensin-converting enzyme 2 (ACE2) receptors. In 2020, an evolutionary analysis of the Delta and Delta Plus variants of SARS-CoV-2 provided a three-dimensional model of the protein of the delta variant.

Structural and phylogenetic analysis of the spike glycoprotein highlighted that the last variants, annotated as omicron, have about 30 mutations compared to the initial version reported in China, while the delta variant, supposed to be the omicron ancestor, shows only 7 mutations.

Abstract:
SARS-CoV-2 has high infectivity and some of its variants have higher transmissibility. To explore the high infectivity mechanism, the charge distributions of SARS-CoV, SARS-CoV-2, and variants of concern were calculated through a series of net charge calculation formulas. The results showed that the SARS-CoV-2 spike protein had more positive charges than that of SARS-CoV. Further results showed that the variants had similar but higher positive charges than preexisting SARS-CoV-2. In particular, the Delta variant had the greatest increase in positive charges in S1 resulting in the highest infec

Abstract:
Background: The current pandemic, COVID-19, is cause by an RNA Coronavirus that was recently identified as SARS-CoV-2. RNA viruses tend to have a high mutation rate; the rate is around a million times greater than that of their hosts. The mutagenic potential of the virus depends on many factors, including the fidelity of nucleic acid-replicating viral enzymes, such as SARSCoV-2 RNA dependent RNA polymerase (RdRp). The rate of mutation drives viral evolution and genome variability, consequently allowing viruses to escape the immunity of the host and develop resistance to drugs. Therefore, the c

Abstract:
New SARS-CoV-2 variants identified around the world could have an impact on current vaccination programmes. What is the latest evidence on the effectiveness of the COVID-19 vaccines used in the UK on new variants? How quickly can these vaccines be updated and approved? What alternative strategies can be used?

Abstract:
In recent months several new variants of the SARS-CoV-2 virus have been detected in various countries around the world. This article examines how these variants arise, how genetic variation might affect the characteristics of the virus, and the possible impact that these new variants might have on the course of the pandemic.

Abstract:
New variants of concern (VOCs) now account for 67% of all Ontario SARS-CoV-2 infections. Compared with early variants of SARS-CoV-2, VOCs are associated with a 63% increased risk of hospitalization, a 103% increased risk of intensive care unit (ICU) admission and a 56% increased risk of death due to COVID-19. VOCs are having a substantial impact on Ontario’s healthcare system. On March 28, 2021, the daily number of new SARS-CoV-2 infections in Ontario reached the daily number of cases observed near the height of the second wave, at the start of the province-wide lockdown, on December 26, 2020.

Abstract:
The Omicron variant of the SARS-CoV-2 virus, which causes COVID-19, has been found across the world since it was first detected in early November 2021. This article describes the characteristics of the variant and its health impacts. It also discusses vaccine effectiveness against the variant and the medium and long-term outlook for the future course of the pandemic.

Abstract:
The science of getting people to start something new is different from the science of getting them to continue positive behaviours. Amid rising rates of new SARS-CoV-2 variants of concern, Ontario needs a refreshed approach to maintaining and enhancing adherence to public health measures. Promising strategies to increase effective masking and physical distancing include persuasion, enablement, modelling the behaviour, and clear education.
