In our study, we conducted surveillance by regular virus testing and detected two positive cases (3.23%) among the 62 recovered medical staff. Surprisingly, Case 1 showed typical clinical and radiological manifestations on admission, while the manifestation in Case 2 was not typical. Moreover, both throat swab and stool tests turned negative in Case 1 before discharge. During home isolation, none of the two cases experienced discomfort, indicating that disease relapse was unlikely.
