Iran is the country in the Middle East most affected by the pandemic in terms of raw numbers, and has announced the death of more than 84,000 people out of more than 3.2 million people infected with the disease. Officials have previously acknowledged that these official numbers remain below the actual.

- Nearly four million deaths -

The Coronavirus has killed 3,964,799 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 on Saturday afternoon.

The United States is the most affected country in terms of raw number of deaths (605,304), followed by Brazil with 521,952 deaths, then India with 401,050 deaths, Mexico with 233,425 deaths, and Peru with 192,902 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.

The World Health Organization, taking into account the excess mortality rate directly or indirectly related to Covid-19, considers that the outcome of the epidemic may be two or three times greater than the officially announced outcome.
