How conservative are the current COVID-19 pandemic global statistics?

After almost a year and a half of the COVID-19 pandemic, the actual case count of those infected with its causative virus – SARS-CoV-2 – remains unclear. Though well over 167.2 million cases have been reported worldwide, this is certainly believed by many to be a massive undercount. A new epidemiological study uses the classical SIR-C mathematical model to find the peak size and date of cases, both documented and unidentified, and the gap between them.
