  As Europe is experiencing a second violent CoVid-19 storm, with the PCR-based
testing system deteriorating due to the high volumes of people to be tested
daily, there is a general reconsideration of the mathematical theories at the
basis of our contact tracing and testing approaches. Drawing upon the concept
of super spreader, we propose the use of (less sensitive) rapid tests to detect
those secondary infections that do not need the use of PCRs, thus saving the
most part of PCR tests currently used. This before the system fails.
