@Carlos --- exactly! Changing information is the very nature of science in the process of producing knowledge. Scientific knowledge is produced by careful observations and inventing theories out of those observations. As this virus was a new pathogenic agent, changing knowledge is inevitable because new observations challenge prevailing theories. Of course we cannot expect the general public to always think as scientists but can educate them. The media outlets have a responsibility in delivering the right information as its the main resource of information to the general public.
