Does the human body produce viruses?
Many of these viruses infect the bacteria that live inside you and are known as bacteriophages, or phages for short. The human body is a breeding ground for phages, and despite their abundance, we have very little insight into what all they or any of the other viruses in the body are doing.

What is an active virus?
Active Viruses: After entering a cell, an active virus immediately goes into action. The virus’s genetic material takes over cell functions, and the cell quickly begins to reproduce. When it is full of new viruses, the host cell bursts open, releasing hundreds of new viruses as it dies.
Can viruses reproduce on their own?
How do viruses multiply? Due to their simple structure, viruses cannot move or even reproduce without the help of an unwitting host cell.
Do viruses lay dormant in your body?
Dormant viruses are not new phenomena. Herpes viruses are often never fully eradicated from the body, and are instead subdued by the immune system. The herpes virus that causes chickenpox and shingles (VZV), for example, remains in our spinal cord cells for life.

Viruses can also be removed from the body by antibodies before they get the chance to infect a cell. Antibodies are proteins that specifically recognise invading pathogens and bind (stick) to them.
