In early 2020, it seemed like people with diabetes were disproportionately dying with Covid-19, but the data provided more questions than answers. What type of diabetes did people have? Were people dying because the condition itself put them at greater risk, or because those with it tend to be older and have other illnesses? And what should people with diabetes do to protect themselves?
Now, researchers are harnessing data from NHS England to address these questions – and some of their findings are unexpected.
It is still unclear whether people with diabetes are more likely to catch the virus.
