You have to consider the epidemiology, not the number of confirmed cases. Back when Iran had a little over 100 cases but had spread it to 3 other countries, epidemiologists estimated there were 18,300 cases. A few days later it had spread to 12 countries from Iran indicating over 100,000 cases. In order to explain the spread now there must be over a million cases. An epidemiologist reported a couple days ago that half of Tehran's 12 million people will soon be infected. Countrywide Iran is likely reaching the saturation point for the first wave if infection. That is why there are reports of burials in mass graves.
Italy has spread it to more than 20 countries more than a week ago indicating the number of infections now is likely around 1 million. They are probably 3 weeks away from reaching the saturation point for the first wave there. We did not get a believable body count from China or Iran, but hopefully we get the real numbers from Italy, so other countries can prepare.
