How Deadly Viruses Kill
The short answer of how highly pathogenic viruses kill people is, they deplete selenium from the cells and organs of the immune system. That eventually can cause multiorgan failure and death. Killer viruses do this by genetically encoding the selenium proteins they need to replicate. This is comparable to how the sun can kill a person if they try to cross a desert with no water. The sun kills by gradually depleting water from a person’s body. Killer viruses kill by depleting the essential selenium that cells, organs, and the human body need to function. The same principle applies. However, most viruses that infect humans are not highly deadly. Only a few are. Adults harbor more than a hundred viruses in their body. Most people are infected by at least one of several herpes viruses. They remain infected for life. While the immune system normally keeps them in check, durin...
