I know it is not common but there are still people that do science, experiments and do not trust authority but just test what works and what doesn't. If you then know business models, marketing and a bit of phycology you can predict what is true or not just watching how they push it on people through the media. Viruses? I don't know but ClO2 works fine against whatever is that stuff. Nuclear bombs... Well nuclear emissions are there. Never tried to reach a nuclear explosion but it's quite simple to verify the cascade action of decay due to neutron emissions. I did the experiment at 16.
