Some of these viruses are completely inert, but others can cause diseases. Viruses have become a regular part of basic biological research as well as clinical therapy. These biological tools are useful because they ’ re derived from viruses that can infect people, cells, and animals. Nervous about handling viruses? That ’ s okay!
