Answer:
Although scientists have been working hard to find a cure to this deadly disease, yet a sudden new like this will not be considered at first to be true. In order to make the public believe in this report, there should be authentic results from the trial experiments showing at least 90% of patient recovery. Also, there should be enough investigation done on the side effects of this medicine and the ingredients used in its making.
