Hur många är smittade i iran egentligen??

On March 3, 23 out of 290 members of parliament—about 7.9 percent—had the disease. (Unlike ordinary people, these MPs probably had reliable access to diagnosis. State media insisted they contracted the disease not from one another, but from their home districts.) The rate of infection of parliamentarians would, if applied to Iran’s total population
, come to 6.4 million cases.
A paper by the University of Toronto’s Ashleigh Tuite and others noted that, by February 23, cases of Iranian origin had surfaced in Canada, Lebanon, and the United Arab Emirates. Given the volume of air travel between Iran and these countries, Tuite’s team estimated how many native COVID-19 cases must have occurred in Iran to produce one case each in these other countries. Their estimate for February 23: 18,300. Since the epidemic reached 100 cumulative cases, the official numbers have doubled roughly every three days. If that rate held, the estimate
as of today would be 586,000.
Let’s consider the other politicians. The senior advisory council has experienced two known deaths out of 39 members; the cabinet has two known infections out of 30. Even if no other council or cabinet members had COVID-19, that’s an infection rate of 5.8 percent.
That would mean an estimate of 4.7 million.
A government website invited Iranians to submit details of symptoms they were experiencing. After 2 million responses, about 9 percent reported COVID-19 symptoms. In the United States, among those whose symptoms and history have led them to be tested for COVID-19, about 10 percent have eventually tested positive. If that rate holds,
Iran would have 730,000 cases.
On March 8, health authorities in Golestan province declared that hospitals there were full. Golestan has about 2.2 percent of Iran’s population, and if we assume it has the same percentage of its hospital beds, the province should have 2,600 hospital beds. Let’s assume that at least some people with other conditions are already in those beds and that roughly 2,000 beds are now filled with COVID-19 patients. About 15 percent of COVID-19 patients need a hospital stay. That suggests that 13,000 people—or about 0.8 percent of the province’s population—have COVID-19 in Golestan. If that rate applies countrywide, it yields 610,000 infections, which suggests a cumulative total of about 1 million infections—if we include those who have already recovered. Finally, because hospitalizations are a lagging indicator, double that number to account for growth in the past week:
2 million.
On March 4 and 5, two evacuation flights of Chinese citizens were allowed to leave Tehran for China’s Gansu province. Chinese authorities were of course wary of introducing more coronavirus carriers into the country, so they tested passengers and found 11 COVID-19 cases out of 311 passengers. If Chinese people in Iran got the disease at the same rate as Iranians, that suggests a rate of 3.5 percent, for a total of 5.7 million at the time of the flight. Tuite, the researcher who studied earlier flights, cautions that this number would undercount total cases, because it represents the number of cases on that plane at that time (the “point prevalence”) and not total cumulative cases—which would be higher,
about 8 million. “It’s alarming, and I have a hard time wrapping my head around the implications of this,” she told me. “But I think it’s possible.”
Undra hur många iranier som är smittade i sverige?? borde kunna räkna på det med ju
