For Eurípedes Donizeti Donzeli, 66, the covid came in a double dose: in February 2021, he was diagnosed with the disease for the first time. Ten months later, a new test confirmed that he had coronavirus again.

“In both situations, I didn’t have any symptoms. In the first episode, I only took the exam because my wife had a fever. In the second, I participated in an end-of-year get-together and discovered that some people present had tested positive”, says the resident. de Franca, in the interior of São Paulo.

But the surprises didn’t stop there: after recovering from the second case of covid, Donzeli was guided by the doctor to do some routine exams, the popular check. “That’s when I found out my glucose was at 146 and I was diagnosed with diabetes afterwards,” she says.
