Longer diabetes duration increases risk of severe COVID-19: study

Researchers have teased out the main risk factors for poor prognosis among people with diabetes, including microvascular complications and comorbidities

Duration of diabetes is a key risk factor for severe and fatal COVID-19, partly explaining why people with type 1 diabetes appear to be at higher risk than those with type 2 disease, UK researchers say.
