Diabetes Type II and Covid-19: Need of Rethinking

In the medical literature, the association between diabetes type II and COVID-19 has been analyzed several times [1-9] with almost the common finding that the disease is a risk factor for COVID-19 infection and death. The increase of ACE2 receptors in diabetic patients [2,4,6,] has been considered as one of the major causes, together with the inflammatory condition and insulin resistance which are common characteristics of diabetes type II [5,6]. Some authors were mentioning that the poorly controlled diabetes represents a risk factor for any infectious disease [8,9]. All these data, despite giving an important contribution to the understanding of the matter, most of the time are related to one country only.
