This paper explores some economic variables that determine the emerging of new COVID-19 variants and the determinants of vaccination advances in 108 countries during a quarterly period from March 2020 to March 2022. We found that more people being fully vaccinated and more education (measured as schooling years) decrease the probability of the emergence of new COVID-19 variants, but more crowded cities and higher percentages of urban population increase that probability. Furthermore, we found that the percentage of fully vaccinated people depends positively on the country's preparation to respond to a health crisis, educational levels, and the index of economic complexity (which measures how diverse in the production of goods and services a country is and the level of its infrastructure), and it depends negatively on the percentage of rural populations (which makes vaccination more difficult).

This study investigates the evolution and genetic diversity of SARS-CoV-2 strains circulating in Morocco to track the spread, clade distributions and mutations of the virus across various regions from February 2020 to June 2024. The genome sequences were retrieved from the GISAID database. A total of 2630 SARS-CoV-2 genome sequences were analyzed using bioinformatic tools such as Nextclade, followed by phylogenetic and statistical analyses.

Purpose: SARS-CoV-2-specific CD8 cytotoxic T lymphocytes (CTLs) are crucial in viral clearance, disease progression, and reinfection control. However, numerous SARS-CoV-2 immunodominant CTL epitopes theoretically are still unidentified due to the genetic polymorphism of human leukocyte antigen class I (HLA-I) molecules.
Methods: The CTL epitopes of SARS-CoV-2 were predicted by the epitope affinity and immunogenicity prediction platforms: the NetMHCpan and the PromPPD.

Introduction: In this study, we analyzed the psychological aspects of coronavirus disease 2019 (COVID-19) patients who were discharged from the hospitals in Shanghai, China, and later had positive nucleic acid retest results for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant infection (re-positive COVID-19). The purpose was to gain clarity on the patients' needs and to provide evidence for the medical staff to deliver scientific and targeted health care to the patients.
Methodology: We screened patients who tested positive for SARS-CoV-2 Omicron variant infection by nucleic acid testing after having previously recovered from a COVID-19 infection and being discharged from Shanghai shelter hospitals or COVID-19-designated hospitals from April 3, 2022, to May 10, 2022.
Introduction: China implemented a dynamic zero-COVID strategy to curb viral transmission in response to the coronavirus disease 2019 (COVID-19) pandemic. This strategy was designed to inhibit mutation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for COVID-19. This study explores the dynamics of viral evolution under stringent non-pharmaceutical interventions (NPIs) through real-world observations.
