Recurrent and More Severe COVID-19 Infection: Two Elderly Case Reports.

Abstract

Although the sensitivity of reverse transcriptase-polymerase chain reaction (RT-PCR) is low in the diagnosis of coronavirus disease 2019 (COVID-19), it is the gold standard. Clinical improvement is prioritized in the follow-up of patients with COVID-19 who are followed as possible or definitive cases. Although the priority in the discharge decision is the resolution of complaints, it is also important to see radiological improvement and RT-PCR negativity. A total of 2 of our patients who were hospitalized and treated in our clinic with a diagnosis of COVID-19 were discharged after their complaints were resolved and their treatment was completed. The patients had 2 negative RT-PCR results at discharge. Both of them presented to the hospital with symptoms such as fever, cough, and shortness of breath after the discharge, and both showed positive RT-PCR results. Considering recurrent COVID-19 infection, we aimed to present treatment and the 2 cases we followed.
