Initial Introduction and Spread of the SARS‐CoV‐2 AY.4.2.1 Delta Variant in Bulgaria, a Genomic Insight
Using genomic epidemiology, the first insights are provided of the introduction of AY.4.2.2 in Bulgaria and the A.3.1.1 sublineage that found larger dissemination only in the United Kingdom.
Seasonal coronaviruses and SARS-CoV-2: effects of preexisting immunity during the COVID-19 pandemic
Preexisting antibodies can help the body protect against SARS-CoV-2 infection, reduce the severity of COVID-19, and rapidly increase the immune response post-infection.
COVID-19: vaccines, efficacy and effects on variants
Three leading strategies of vaccine development against coronavirus disease 2019 (COVID- 19): mRNA vaccines, adenoviral vector vaccines and recombinant nanoparticles are reviewed and the evidence for the effectiveness of the vaccines against those five VoC is explored.
SARS-CoV-2 Therapeutic Landscape, Opportunity and Future Threats
Developing a global viral, fungi and microbes platform can help to predict mutations on their genomic, structural and pathophysiological profile to better address early on future threats by such infectious agents.
SARS-CoV-2 surveillance in Italy through phylogenomic inferences based on Hamming distances derived from pan-SNPs, -MNPs and -InDels
An analytical workflow for identifying accurately the PANGO lineages of SARS-CoV-2 samples and building of discriminant minimum spanning trees (MST) bypassing the usual time consuming phylogenomic inferences based on multiple sequence alignment (MSA) and substitution model.
Quarantine and testing strategies to ameliorate transmission due to travel during the COVID-19 pandemic: a modelling study
The minimum travel quarantine duration such that the infection rate within the destination country did not increase compared to a travel ban is identified, defining this minimum quarantine as “sufficient” and providing guidance for travel policy during all phases of pandemic diseases.
Guide pratique à l’intention des laboratoires cliniques pour les tests de sérologie du SRAS-CoV-2
Le répertoire des tests de diagnostic disponibles du coronavirus du syndrome respiratoire aigu sévère 2 (SRAS-CoV-2) évolue rapidement. Bien que les tests sérologiques aient une capacité de
