ABSTRACT
Diabetes mellitus (DM) is an important risk factor for both severe disease and death due to coronavirus-2019 (COVID-19). About 19 million of the 463 million persons living with DM (PLWD) globally are found in sub-Saharan Africa (SSA). The dual burden of DM and poverty in SSA, coupled with the rising number of cases of COVID-19 in this region, predisposes PLWD to inadequate care and poor glycemic controls due to the disruption to the economy and the healthcare system. The risk of acquisition of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) among PLWD is the same as those in the general population. Therefore, the standard preventive measures outlined by the World Health Organization must be strictly adhered to. In addition, maintaining adequate glycemic control is associated with better outcomes in DM patients with COVID-19. In SSA, adequate supply of DM medication while patients stay at home is crucial to minimize routine hospital visits since DM clinics are usually overcrowded and have longer waiting times, which may maximize risk of SARS-CoV-2 transmission to PLWD across the region. Psychosocial support to improve adherence to anti-hyperglycemic medications may improve COVID-19 outcomes. Trained healthcare professionals should diagnose and evaluate severity comprehensively as well as evaluate the need for in-patient care for PLWD with COVID-19 irrespective of disease severity. Due to the increased risk of severe disease, a multi-disciplinary approach to the management of COVID-19 in PLWD should preferably be in a setting where close monitoring is available, typically a health facility, even for mild disease that may require home management according to local guidelines. In conclusion, DM complicates COVID-19 outcomes and the on-going COVID-19 pandemic adversely affects DM care at individual and global public health levels. PLWD should be prioritized as COVID-19 vaccines are being rolled out.
