The human immune virus cannot reproduce without host cells.
<h3>Human immune virus</h3>
The human immune virus is an RNA virus that only becomes active in human hosts.
When the virus gains access into a suitable host, it embeds its genome into that of the host and as such, the genetic machinery of the host is utilized to multiply the genome of the virus.
With time, the virus gradually takes over the host's genome system and breaks down their immune system, making them susceptible to diseases.
