| 13 | Current understanding of the impact of COVID-19 on gastrointestinal disease:Challenges and openings显示文摘The novel coronavirus disease-2019(COVID-19)is caused by a positive-sense single-stranded RNA virus which belongs to the Coronaviridae family.In March 2019 the World Health Organization declared that COVID-19 was a pandemic.COVID-19 patients typically have a fever,dry cough,dyspnea,fatigue,and anosmia.Some patients also report gastrointestinal(GI)symptoms,including diarrhea,nausea,vomiting,and abdominal pain,as well as liver enzyme abnormalities.Surprisingly,many studies have found severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)viral RNA in rectal swabs and stool specimens of asymptomatic COVID-19 patients.In addition,viral receptor angiotensin-converting enzyme 2 and transmembrane protease serine-type 2,were also found to be highly expressed in gastrointestinal epithelial cells of the intestinal mucosa.Furthermore,SARS-CoV-2 can dynamically infect and replicate in both GI and liver cells.Taken together these results indicate that the GI tract is a potential target of SARS-CoV-2.Therefore,the present review summarizes the vital information available to date on COVID-19 and its impact on GI aspects. | Tarun Sahu Arundhati Mehta Yashwant Kumar Ratre Akriti Jaiswal Naveen Kumar Vishvakarma Lakkakula Venkata Kameswara Subrahmanya Bhaskar Henu Kumar Verma | 2021 | World Journal of Gastroenterology2021，27，6： | 0 |
