A few countries still have somewhat precise numbers. UK has the ZOE health study, which found over 1 million people currently being infected out of roughly 50 million (from memory; I don't know how many people live in UK).
Germany has the SentiSurv study, indicating incidences approaching 1000 again. While the latter is only a survey in a few major cities, it allows calculation of a dark figure when put in relation to officially registered cases, which can then be applied to all regions that have the same criteria for when to test.
Overall, not great that millions will miss a chance to get the upcoming vaccine that would provide very decent protection against the most common strains.
