Background & Objective: The 2019 coronavirus disease (COVID-19) is a highly contagious disease that has affected people in several countries around the world. COVID‐19 has been announced a pandemic by the World Health Organization (WHO). Unfortunately, in some cases, COVID-19 diagnosis tests are confirmed positive again after the recovery of patients and or discharge from the hospital. This study aimed to evaluate the symptoms of patients in whom coronavirus testing was recurrent positive.

Results: Studies have shown that in some patients, after a coronavirus test is negative and after the patients are discharged from the hospital, the RT-PCR test is positive again without contact with another patient.
