COVID-19, the disease caused by SARS-CoV-2, has been disruptive worldwide. It was primarily a respiratory disease that affected many of the medically vulnerable, but the true impact of postacute sequelae of SARS-CoV-2 (PASC), which has been demonstrated to involve all organ systems, is now coming to light. In addition, a new disease entity emerged, multisystem inflammatory syndrome in children (MIS-C), which has had significant morbidity and mortality associated with it. This issue reviews the presentation, evaluation, and management of patients with COVID-19, MIS-C, and PASC. Additionally, the current literature supporting public health measures, as well as COVID-19 vaccinations and their complications are discussed.
