If nature is really in favor of viruses, what can humanity due to ensure our safety in the face of deadly viruses?

The short answer is that we can never be totally safe from viruses. Viruses are a part of life. Our overuse of antibiotics and obsession with hand sanitizers and cleaners, have made us even more susceptible to viruses. With deadly viruses like Ebola, the world needs to act quickly. The recent Ebola outbreaks in Africa are an example of how quickly viruses like this can spread all over the world. There must be plans of education and fast containment on a global level to better our chances against viruses like Ebola.
