Italy on Wednesday reported 475 new deaths from the novel coronavirus, the highest one-day official toll of any nation since the first case was detected in China late last year.
Total deaths in Italy have reached 2,978, more than half of all the cases recorded outside China, while the number of infections stood at 35,713.
The previous record high of 368 deaths was also recorded in Italy, on Sunday.
Italy, a nation of 60 million, has now recorded 34.2 percent of all the deaths officially attributed to COVID-19 across the world.
