Frequently Asked Questions

Are viruses ever alive?

Death is what happens when a living organism stops performing biological functions, and for the moment we’re only interested in the active particles. So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy.

Are viruses living or non-living entities?

In many ways whether viruses are living or non-living entities is a moot philosophical point. There can be few organisms other than humans that have caused such devastation of human, animal and plant life. Smallpox, polio, rinderpest and foot-and-mouth viruses are all well-known for their disastrous effect on humans and animals.

What is something that is not alive?

Something that is not alive, such as a virus, does not have self-generated or self-sustaining actions, he said. "I don't think viruses qualify as being alive.

What happens when a virus is inactive?

Some viruses cause no apparent changes to the infected cell. Cells in which the virus is latent and inactive show few signs of infection and often function normally. This causes persistent infections and the virus is often dormant for many months or years. This is often the case with herpes viruses.
