COVID-19 project believes infections estimates should include all infected individuals of the SARS-CoV-2 virus, not just those that took a COVID-19 test and tested positive. As of January 2021, they estimate the true number of infected individuals in the US to be roughly 2-4x higher than the reported cases (20-50% detection rate). See our writeup, Estimating True Infections, for a more detailed look into this subject. Because not all currently infected individuals are infectious, they recommend dividing the “currently infected” estimate by 2-4 to get a sense of the number of currently infectious individuals.

Confirmed Omicron cases, deaths, and admissions
France, Israel, Denmark, and Ireland have the highest cases per capita of Omicron in the world. This shows what happens with massive surges of virus spread, even ones with 60-70% less severity.
