According to the latest US research, published in April in the journal Nature, Covid-19 survivors were about 39% more likely to have a new diabetes diagnosis in the six months after infection than non-infected users of the veterans’ affairs health system. The risk works out to about 6.5 additional diabetes cases for every 1 000 Covid-19 patients who don’t end up in the hospital. For those who do, the probability jumps to 37 per 1 000 and it’s even higher for patients who required intensive care.

Other explanations may include an acute stress response to the infection, the use of steroid treatments that help survival but increase blood-sugar, or just the unmasking of diabetes cases that had previously escaped diagnosis, according to John Nicholls, a clinical professor of pathology at the University of Hong Kong.
