It has long been known that benign coronavirus species are capable of causing 15 – 30 % of common colds (usual symptoms: runny nose, cough, sore throat). This reality was recently mentioned by an internationally-famous virologist from Germany, in an interview where he also admitted that laboratory confirmation of COVID-19 is next to impossible given the high incidence of both false-positive "COVID-19" PCR swab tests and false positive "COVID-19"  serum antibody tests.

Apparently, neither test seems to be able to distinguish between the benign coronaviruses that can cause common colds and the more serious coronavirus that actually causes COVID-19!!
