Chlorine Dioxide falls into the category of ways to kill a virus that will also kill us. Your second source argues that it is effective at levels "below the long-term permissible exposure level to humans, namely 0.1 p.p.m.", but I would imagine there are still health concerns to using this method. Additionally, that figure is the needed concentration to control the influenza virus (in mice), it is not clear how well this number generalizes to other viruses. While it is nice to have a worst case scenario plan, I suspect the reason the CDC isn't testing it is because they do not believe we will be in a situation where using it is better then the alternative. If we were in a situation where Chlorine Dioxide was a good idea, I suspect even the pharmaceutical companies would be supportive.
