By searching PubMed, Medline, Scopus, Embase, Google Scholar, and PakMediNet databases, an online literature search was conducted from March 2020 to November 2021. Guidelines for reporting systematic reviews and meta-analyses (PRISMA) were used. There were 660 publications found, of which 27 were original studies involving 3241 COVID-19 patients were selected. In the COVID-19 patients with new-onset diabetes, mean age was 43.21±21.00 years. Fever, cough, polyuria, and polydipsia were the most frequently reported symptoms, followed by shortness of breath, arthralgia, and myalgia. The developed world reported (109/1119) new diabetes cases (9.74%), while the developing world reported (415/2122) (19.5%). COVID-19 new-onset diabetic mortality rate was 470/3241 (14.5%).
