epidemiology and risk factors

This retrospective observational study aims to explore associations between PM2.5 and COVID-19 severity amongst PwMS.

The objective of this systematic review and meta-analysis was to review the evidence on the effectiveness of public health measures in reducing the incidence of COVID-19, SARS-CoV-2 transmission, and COVID-19 mortality.

The objective of this study was to investigate the association of SSRIs with outcomes in patients with COVID-19 by analyzing electronic health records (EHRs).

The objective of this study was to derive and validate risk prediction algorithms to estimate the risk of COVID-19 related mortality and hospital admission in UK adults after one or two doses of COVID-19 vaccination.

This study aimed to identify risk factors for post-vaccination SARS-CoV-2 infection and describe the characteristics of post-vaccination illness.

In this study the authors trialled daily testing of contacts as an alternative to assess whether this resulted in similar control of transmission, while allowing more school attendance.

This critical review highlights the injury pathways possible through SARS-CoV-2 infection that have the potential to increase and contribute to cognitive impairment and dementia.

In this article the authors detect auto-Abs neutralizing 100-fold lower, more physiological, concentrations of IFN-α and/or -ω in 13.6% of 3,595 patients with critical COVID-19, including 21% of 374 patients > 80 years, and 6.5% of 522 patients with severe COVID-19.
