Management of gastrointestinal endoscopy unit during post covid-19 endemic outbreak: A report from Wuhan epicenter.

The COVID-19 pandemic is caused by severe acute respiratory syndrome coronavirus 2 and causing a global public health emergency. During the outbreak, Wuhan was the first reported and hardest-hit city. With the dramatic drop in number of confirmed cases and subsequent ending of Wuhan lock down, asymptomatic carriers and patients in their recovery period still pose an increased risk.

Performing EUS during COVID-19 postendemic period: A report from endoscopy center in Wuhan.

In early April 2020, the 3-month-long city-wide lockdown was lifted in Wuhan, the epicenter of China during Coronavirus Disease 2019 (COVID-19) global pandemic. However, continuing precautions are still practiced considering the risk of transmission from asymptomatic carriers. Given that COVID-19 is spread via airborne droplets, including aspiration of oral and fecal material through endoscopes, our endoscopy center has strategically assigned health-care providers to ensure triage workflow and to minimize concomitant exposure from potential asymptomatic carriers.
