The outbreak of COVID-19, caused by the novel coronavirus SARS-CoV-2 began in December 2019 in Wuhan, China. Acute respiratory complications during SARS-CoV-2 infection were the first focus of interest of the medical community especially in people with comorbidities. Today, post covid has become a worldwide public health problem, with organizations such as Santé Publique France estimating that 30% of patients have this syndrome. In this work, Dr. Rebouh focuses on the sequelae in patients who survived COVID-19, examining the clinical data and exploring the underlying pathological mechanisms. By providing an in-depth analysis of this critical issue, this study contributes to the overall understanding of the effects of COVID-19 on human health, and paves the way for new preventive interventions.
