Even though COVID-19 is mainly a respiratory illness, around 20–50% of patients report gastrointestinal symptoms, which may be explained by the presence of angiotensin-converting enzyme 2 (ACE2) receptors on the gastrointestinal tract and the ability of the virus to persist in the gut even longer than in the respiratory system [3,4]. The gene discussed is ACE2; the disease is COVID-19.
