Answer:
Beneficial viral infections
Some viruses we come across protect humans against infection by other pathogenic viruses. For example, latent (non-symptomatic) herpes viruses can help human natural killer cells (a specific type of white blood cell) identify cancer cells and cells infected by other pathogenic viruses.
The importance of a virus is not due to the virus itself, but to the hosts they infect and affect, and many viruses are important because they cause diseases in humans, animals, or crops.
In fact, some viruses have beneficial properties for their hosts in a symbiotic relationship (1), while other natural and laboratory-modified viruses can be used to target and kill cancer cells, to treat a variety of genetic diseases as gene and cell therapy tools, or to serve as vaccines or vaccine delivery agents.
Bacteria can be friends and foes—causing infection and disease, but also helping us slim down and even combating acne. Now, a new study reveals that viruses have a dual nature as well. For the first time, researchers have shown that they can help our bodies fight off invading microbes.
Impact on human health
The human virome is a part of our bodies and will not always cause harm. Many latent and asymptomatic viruses are present in the human body all the time. Viruses infect all life forms; therefore the bacterial, plant, and animal cells and material in our gut also carry viruses.
