Currently, there are seven types of coronaviruses that can infect humans. Among them, severe acute respiratory syndrome coronavirus (SARS‑CoV), middle east respiratory syndrome coronavirus (MERS‑CoV) and severe acute respiratory syndrome coronavirus‑2 (SARS‑CoV‑2) are three types of coronavirus which have the greatest impact on human health in the past 20 years. Diabetic patients with hypoimmunity may have adverse outcomes and different injury mechanisms when infected with coronaviruses. This review is about the advance on clinical characteristics and injury mechanism of diabetic patients with SARS‑CoV, MERS‑CoV, or SARS‑CoV‑2. The purpose of writting this review is to arouse the attention of clinicians to diabetic patients with coronavirus infection and provide help for clinicians in the treatment of coronavirus disease 2019. © 2021, Editorial Board of Medical Journal of Wuhan University.
