Always ask, when the Native Americans were exposed to European diseases hundreds died instantly. And then the infection rates went down until herd immunity was acheived. Same happened here in communities where most people were exposed to coronavirus for the first time; first the death rate was extremely high and then it went down BEFORE the vaccine was distributed. Also, the varients vary in intensity and the Delta varient has mutated to the point where it is not as vicious as the original version. All varients were increasingly more moderate to the point that the death rate went down drastically before vaccination distribution. The rates are climbing now after vaccination distribution.
There are ways of treating covid-19 with medication which would’ve lowered the initial as well as the current death rate, but many health professionals ignore those treatments as does the CDC and WHO and the MSM who not only do/did they ignore this info but they also made fun of Trump’s promoting certain medications successfully treat covid-19.
