Investigation of the possibility of catching a COVID-19 lower gastrointestinal waste (A Systematic Review Study)

Introduction: Gastrointestinal tract may act as a transmission route of infection apart from the respiratory tract in the spread of viral diseases. Covid pneumoniae 19 is a highly contagious infectious disease. There is growing evidence that patients with Covid 19 can develop gastrointestinal symptoms. The present study was performed to investigate the possibility of Covid 19 infection through the lower gastrointestinal tract. Methods: The present study is a systematic review study using the English keywords Gastrointestinal, Endoscopy, SARS-CoV-2, COVID-19 in the international international databases Pub Med, Science Direct, Google scholar from January to May 2020. AD is done. The total search for related resources was 474 articles and finally 22 articles were selected. Results: Although Covid 19 often causes respiratory symptoms; But gastrointestinal manifestations may be just the first sign in some patients with Covid. Emerging evidence suggests persistence of SARS-Covid-2 virus RNA in fecal samples even after a negative breath test, and the gastrointestinal tract may be a potential route for transmission of Covid-19 infection. Conclusion: We recommend that RT-PCR be performed before lower endoscopy; Even in cases where respiratory RT-PCR is negative, it can be considered as a standard in the guidelines of health commissions.
