Due to COVID-19 which is the public health emergency of international concern(PHEIC),through ward construction management,human resource deployment,staff emergency  training,logistic  support  and  so  on,the  general  orthopedic  ward  was  replaced  and converted into a fever emergency observation ward within 7  hours. The process was fast, orderly, scientific and safe. This will provide a reference for the subsequent establishment of isolation wards.
