Abstract

The severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) dwells in the respiratory airways, however, its digestive tract presence, infectivity, mucosal attachment and penetrating mechanisms, enteric proliferation, stool shading, flashed bio-aerosol spreading and fecal-oral transmission is far from being understood. The present review opens some skylights to lighten the long, tortuous, dark and challenging tunnel of the gastrointestinal tract and his uninvited covid-19 viral new inhabitant.
