There was a spike in non-influenza related pneumonia cases prior to the outbreak, particularly in Australia where it's not flu season. My wife caught it in early March and developed mild bacterial pneumonia but tested negative for flu and Covid-19. Part of the argument for natural evolution is that there are mutations that most likely occured in a human host as they indicated adaption to an immune response. My personal theory is that an individual infected with this unknown virus that was going around came into contact with the bat originated coronavirus in Wuhan (which may or may not have originated in the lab). RNA was exchanged and a novel variation emerged that was now both highly contagious and deadly. But I am not an epidemiologist.
