Long COVID-19, radiological findings, and its management: a systematic review

ABSTRACT

Background: COVID-19 is a disease caused by SARS-CoV-2 and has numerous clinical spectrums. Mild respiratory infection is the common clinical manifestation of COVID-19, and the less common is pneumonia accompanied by fever, cough, and breathing difficulty. Long COVID can be defined as prolonged signs and symptoms which cannot be explained for other reasons 4 weeks after being diagnosed with SARS-CoV-2. This study aimed to describe the cause of illness is confirmed or suspected COVID-19 patients, specifically on long COVID. Subjects and Method: We performed literature searches of the latest articles with Medline, CINAHL (EBSCO), Global Health (Ovid), WHO Global Research on COVID-19 database, LitCovid and Google Scholar databases published from 2019 to 2020. Two reviewers searched all articles independently (P and W, with 7 and 10 years of experience, respectively). We conducted a systematic review to provide recent evidence of symptoms and complications in long COVID. We followed PRISMA guidelines.
