Coronavirus disease 2019 (COVID-19) is still pandemic all over the world. Patients requesting screening in emergency departments (ED) have continually increased. Establishing additional screening stations outside of the ED to increase the number of patients tested and protect the safety of health care workers poses an urgent challenge. We employed a container house near the entrance of an ED to create an outdoor screening station, which separates suspected patients of COVID-19 from regular emergency patients to prevent cross infections. In our experience, a container house station can not only provide additional screen area but also reduce the consumption of personal protective equipment. Container houses are sturdier than tents and can be fully assembled rapidly. Appropriate protective equipment can be installed with them to fulfill demands for COVID-19 screening.
