In theory. In practice, the body is the battlefield and using very strong (toxic) drugs to pursue a scorched earth policy type health agenda tends to cost humans more than it costs pathogens. If you successfully ruin this pathogen but also ruin the host, something steps in and that something tends to be something we cope with even less well, much like many Native tribes were decimated by "common" European diseases upon initial exposure because they had no immunity.
