WebMar 27, 2024 · In order for a virus like the COVID-19 virus to be detected early in the body using real time RT–PCR, scientists need to convert the RNA to DNA. This is a process called ‘reverse transcription’. They do this because only DNA can be copied — or amplified — which is a key part of the real time RT–PCR process for detecting viruses. WebPurpose: At present, it has been found that managing patients with a redetected positive RNA test after recovery from foreign-imported coronavirus disease 2024 (COVID-19) cases in China is challenging. The purpose of the current study was to describe the clinical characteristics of these patients.
