What kind of monkey gibberish is that?
Once you get a cold or flu it never leaves you?
No. It's truth. Viruses do not die. They are either active or dormant.
"Strictly speaking, viruses can't die, for the simple reason that they aren't alive in the first place. Although they contain genetic instructions in the form of DNA (or the related molecule, RNA), viruses can't thrive independently. Instead, they must invade a host organism and hijack its genetic instructions."
I remember reading the book The Hot Zone about the ebola virus. They discussed how ebola will never die. It's a virus. Viruses need hosts. When the virus's host dies, the virus goes dormant. Say a healthcare worker touches the dead body, the virus "could" become active with that healthcare worker, the host. Or not, depending on the immunity of the host and a thousand other reasons.
I could have ebola, walk into a cave and scrape my finger on a rock. Leaving the virus on the rock. It won't die, it will just go dormant. If another human comes along and scrapes their finger on that rock, the virus could embed itself in that human and become active again.
The flu and other viruses come back year after year and mutate. They don't die. We can become, as humans, more resistant to them. The viruses morph over time. They don't go away.
