What’s the point of antibody tests if they can’t discern the difference between covid19 antibodies and other Coronaviruses? Why are people carrying on like this is some kind of stopgap solution?
Were any of the other coronaviruses wide-spread in the west? If not, then it still seems ok.
There are many strains of Coronavirus. 4 of them are what we diagnose as the common cold.
Six species of human coronaviruses are known, with one species subdivided into two different strains, making seven strains of human coronaviruses altogether. Four of these coronaviruses continually circulate in the human population and produce the generally mild symptoms of the common cold in adults and children worldwide: -OC43, -HKU1, HCoV-229E, -NL63.[72] Coronaviruses cause about 15% of commons colds.[73] The majority of colds are caused by rhinoviruses.[74] The four mild coronaviruses have a seasonal incidence occurring in the winter months in temperate climates.[75][76] There is no preference towards a particular season in tropical climates.[77]
