A virus is a non-cellular, infectious entity made up of genetic material and protein that can only infiltrate and replicate within the living cells of bacteria, plants, and mammals.
Many dormant and asymptomatic viruses are always present in the human body.
Humans can carry many latent viruses – which are viruses that remain dormant until it is triggered due to a specific factor.
In fact, the viruses collectively inhabiting the human body is known as the human virome.
It has been estimated that the human virome contains approximately 380 trillion viruses.
