- More than four million deaths -

The coronavirus has killed 4,086,242 people in the world since the World Health Organization office in China reported the emergence of the disease at the end of December 2019, according to a census conducted by Agence France-Presse based on official sources Sunday at 10:00 GMT.

The United States is the most affected country in terms of raw number of deaths (608,898), followed by Brazil with 541,266 deaths, India with 413,609 deaths, Mexico with 236,240 deaths, and Peru with 195,047 deaths.

The numbers are based on daily reports issued by health authorities in each country and exclude subsequent reviews by statistical agencies that indicate much higher death numbers.
