> being infectious before showing symptoms is just a fact of this disease. Sure, I can buy that. Virus particles are multiplying to a low enough level to infect another source without causing full blown symptoms. However, bear in mind that most of these infections will spread when particulate moisture droplets are expelled. Why do you think that some of the symptoms are cough and sneezing for some infectious diseases? It's an enriched feature of the infection to increase it's likelihood to spread. So, whereas a person that is contagious without sneezing/coughing may spread the disease, it'd be through saliva, such as sharing drinks, kissing, etc. Since I don't go around kissing, drooling, or otherwise spreading my saliva around on people, it's really unlikely that a person will be as infectious/contagious as a CoVid carrier after symptoms show. >> One could make a persuasive argument that avoiding spreading to others necessarily includes avoiding contracting the infection in the first place I could make a persuasive argument that all of the infected need immediately incinerated with a flammenwerfer, too, since fire will destroy all the infections that might spread around. By killing all of the disease particles, there need not be fear of further infections. That doesn't mean my argument is particularly sound, but I could make it nevertheless. >> And the best way to do this is boost your immunity through a vaccine (in addition to the semi-isolation measures already taking place). Probably the best way, other than catching the disease and working through it. By the time vaccines are in full production, my bet is that spring weather and sunshine will have already eliminated most of the free virus particles in the environment and this episode will move into the SARS/MERS category of being forgotten for another 10-15 years.
