Impact of diabetes on COVID-19 and other infection: Report from the 22nd Hong Kong Diabetes and Cardiovascular Risk Factors-East Meets West Symposium.

The coronavirus disease 2019 (COVID-19) pandemic has posed enormous challenges to healthcare systems worldwide. The negative impact of COVID-19 is widespread and includes not only people who contracted the disease but also those with chronic morbidities such as diabetes whose care is compromised due to diversion of medical resources. People with diabetes are generally more susceptible to infection as a result of altered immunity. People with diabetes have a worse prognosis from COVID-19 and there is evidence to suggest that severe acute respiratory syndrome coronavirus 2 may directly affect pancreatic function precipitating hyperglycaemic crises. In the United Kingdom, one of the most heavily affected countries, guidelines are in place to unify the management of people with diabetes hospitalised for COVID-19. Diabetes services are re-organised to ensure that medical care of people with diabetes is maintained despite resource and other practical constraints. Public health measures including social distancing, hand hygiene and the use of face masks are crucial in containing community transmission of the virus. Hong Kong, one of the most densely populated city in the world, is particularly vulnerable and has in place a stringent containment policy and aggressive contact tracing to ensure public safety during this pandemic.
