Not minimising, but to fact check: he was not the "chief medical officer of Italy". He was a primary care doctor, a GP, who was also President of the Medical Association of Varese, a city in the North of Italy. He was caring for patients but got infected and was admitted to hospital himself on 6 March. And he died on Tuesday 10 March, it's just getting wider reporting now. Probably a lot because of the assumption that "medical chief" means the top doctor in the country, rather than a doctor who holds an administrative position in something like the Italian regional GMC.
