Core Tip

Core Tip: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection can progress to a severe respiratory and systemic disease named coronavirus disease–2019 (COVID-19). Nevertheless, SARS-CoV-2 can also generate a gastrointestinal infection. In this review, we explore the impact of COVID-19 on the gastrointestinal system, gut microbiome, and the gut-lung axis and the severity and possible implications and interventions in COVID-19 patients.
