So this German peer-reviewed study, dated April 6, concluded that only an average of 6% of cases worldwide were actually detected:
Instead of doing that, I'm simply going to state what is less obvious. As the "one out of every ___" gets to be closer to 100% infection, the R0 naturally diminishes simply due to each person having fewer uninfected hosts to infect. Also, it goes from 50% infected to 100% infected just as fast as it has been doubling when the numbers were far smaller. Today, 1 in 12 Italians have been infected by the coronavirus, according to this estimate.

So if Italy had 9,172 confirmed cases on March 9, they would have had more than 260,000 actual infections at that time. The study estimates that Italy then had "around 3 million" (1 in 20 Italians infected) on March 31, three weeks ago. Sixteen days later, Italy eased its lockdown. On that day, April 15, there were 162,488 confirmed cases. This, according to the study indicates that about 4.6 million (more than 1 in 15) had been infected by then, which is consistent. This is more than a seventeen-fold increase during the lockdown. From this, a doubling rate can be extrapolated and then applied to the overall population to estimate how long until the entire country will have been infected by the SARS-CoV-2 virus.Insufficient and delayed testing may explain why some European countries, such as Italy and Spain, are experiencing much higher casualty numbers (relative to reported confirmed cases) than Germany, which has detected an estimated 15.6% of infections compared to only 3.5% in Italy or 1.7% in Spain. Detection rates are even lower in the United States (1.6%) and the United Kingdom (1.2%) – two countries that have received widespread criticism from public health experts for their delayed response to the pandemic.
In sharp contrast to this, South Korea appears to have discovered almost half of all its SARS-CoV-2 infections. The authors estimate that on 31 March 2020, Germany had 460,000 infections. Based on the same method, they calculate that the United States had more than ten million, Spain more than five million, Italy around three million and the United Kingdom around two million infections. On the same day the Johns Hopkins University reported that globally there were less than 900,000 confirmed cases, meaning that the vast majority of infections were undetected.
