The symptoms and time of infection along with the chronic diseases of the patient predetermine the intensity level of coronavirus. These factors also determine the chances of surviving and recovering. The symptoms of the recent coronavirus (COVID-19) can be mild to severe. They do not necessarily show up within a day after the infection gets into the human organism. It might take from a couple of days or even two weeks (or longer, in rare cases) for the signs of COVID-19 to show up.
