official covid figures from 2020 indicate that covid never exceeded previous years' flu incidence rates. there was less covid in 2020 than there was serious diagnosed flu in 2019, 2018, 2017, 2016, 2015 and earlier. the symptoms of covid are less severe than those of a serious case of flu.   because the causes of those symptoms (flu and colds) are environmental, not viral of bacterial. think fishbowls. how do fish get sick, and how do you heal them? do you clean the water? or do you inject the fish to make his insides clean? the dirty environment's just gonna make the fish more sick. workplaces get dirty all the time, some more often than others.
