  • The etiological agent is SARS-CoV-2, named for the similarity of its symptoms to those induced by the severe acute respiratory syndrome, causing coronavirus disease 2019 (COVID-19), is a virus identified as the cause of an outbreak of respiratory illness first detected in Wuhan, China.[1][2]
  • The growing number of patients however, suggest that human-to-human transmission is actively occurring.[3][4]
  • The outbreak was declared a Public Health Emergency of International Concern on 30 January 2020.

Pathophysiology

  • SARS-CoV-2 uses the Angiotensin-converting enzyme 2 (ACE2) and the serine protease TMPRSS2 receptors for cell entry. These receptors are presently abundantly not only in the lungs but also in the enterocytes of the small intestinal.[5][6] Other sites of expression of the receptors in the gastrointestinal tract are-the upper esophagus, liver, and colon. [5]
  • Entry of the virus causes disruption of the enterocytes and may lead to inflammation and alteration of intestinal permeability.
  • COVID- 19 is being treated by atrial of many different antivirals and antibiotics. Diarrhea could also be a result of an alteration of the gut microbiota due to any of these. [7]
