This WSJ report on critical analysis of coronavirus data has a very useful chart of Estimated Range of Symptomatic Cases Reported by Country. Complete coronavirus data for all symptomatic persons who have the coronavirus infection is lacking in most countries. Many people in large populations have symptoms and are positive but are not reflected in the official data collection. This is a big problem as the total number of cases are understated by a magnitude of twice to five times the numbers reported in official tally. South Korea has done a good job of getting more of the symptomatic people with the infection in its data, as about 53% to 90% of such persons are reflected in official data. Next comes Germany at a range of 38% to 55%. China comes third and has about 28% to about 38% of such persons reflected in its data, the U.S. currently on April 4 at about 14% to 19%, according to this chart in the WSJ. The source for this is Mathematical Modeling Center at the London School of Hygiene and Tropical Medicine. What this means is that the US. number of cases at 278,000 reported infected people with symptoms (April 4) is only 14% to 19% of the true number. Another way to say this is that the actual infected persons with symptoms is about 5 times what is reported, or over 1 million not the 278,000 reported. As happens for China data collection agencies may never get the true number. To be comparable to the Chinese numbers, as the U.S. is a large country, the figure closer to the true numbers would be twice the 278,000 reported or over half a million symptomatic infections of coronavirus in the U.S. Why is this data important. With widespread testing as in South Korea one gets data that tells one how many people are infected (the size of the problem) and therefore the resources needed and the point of greatest impact. Also it tells one the typical transmission rate per person, and it helps hospitals in each area know what to expect and what resources are needed to prepare- not find people suddenly turn up in the E.R. in unpredictable numbers. The lack of widespread testing and better reporting in the data to get a grip on the pandemic is shown in this chart for countries hardest hit, less than 5-6% for Italy and Spain. The UK and France at 5-8%. ...
