The coronavirus disease 2019 (COVID-19) pandemic has irrevocably changed the way the world functions. In particular, the pandemic resulted in unspeakable horrors in the healthcare field. The incidence and severity of many diseases varied as a result, and many researchers have attempted to identify what changes occurred in society, health, and people’s lives during this period. Research on adults and youth with type 1 diabetes mellitus (T1DM) has focused on its occurrence, causes, and clinical aspects. Until now, there has been controversy about whether the increased incidence of T1DM and/or the severity of clinical symptoms are directly related to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection [1-4]. However, these articles proved that during the COVID-19 pandemic, the incidence of newly diagnosed T1DM in children increased, and clinically more severe symptoms appeared [1,5,6]. In addition, significant increases were observed in the global rates of diabetic ketoacidosis (DKA), severe DKA, high blood sugar, and glycosylated hemoglobin levels among children [6,7]. A possible cause is the poor accessibility of hospitals, as care for non-COVID-19-related diseases was reduced to control COVID-19 infection in healthcare institutions. Furthermore, many avoided hospitals to minimize exposure to SARS-CoV-2 [6,8]. In addition, infection in children is potentially associated with pancreatic islet autoimmunity, promoting progression to apparent T1DM or precipitating stressors [9]. Therefore, some researchers have proposed that timely access to healthcare, an increase in public and healthcare providers’ awareness of T1DM symptoms through public health education and screening campaigns, and proper diabetes management during pandemics or similar situations remain essential and key to avoiding similar increases in incidences of DKA or severe DKA in the future [10].
