The covid is another illustrous episode

The covid is another illustrous episode in the history of humanity. Before Covid didn’t exist and now after all the thinking in universities there is a new disease. So all the study was not to have one fewer disease, after all the study we have one more terrible disease. Who is responsible?, is there anyone investigating why the new virus appeared?. Medicine is to erradicate diseases. In the dark ages prisoners in cages could not get Covid because Covid didn’t exist. Is humanity going backwards?. Share if you dare and care. Thank you
