Viruses are not technically alive outside of a host. And just how long they can exist outside a host is unknown. So, Adam and Eve had to have had most if not all the viruses by kind, and they lived close to a 1000 years . . . I say that is interesting.
Seeds and pollen, which are in some ways similar to viruses, can remain dormant for thousand(s) of years and in many cases largely unaffected by entropy, in that they still function. But a virus, we don’t know just how long they can exist outside a host and or entropy’s affect on their function.
I think it is very likely that Adam and Eve were rarely ill, we know they lived very long lives, and they had to have had all the viruses. Those things can’t be a coincidences . . . in my world view those items are what I call, clues. Clues to a long healthy life on earth.
Another clue is the bowhead whale, it just “happens” to be the longest living animal on earth at 200 years. And then there is the sea turtle, some say turtles may live 400 or 500 years, we just don’t know. Is it a coincidence that both of the longest living creatures on earth, are creatures that would not have been virus isolated during Noah’s flood? And without any question there are more viruses in the ocean than there are on dry land, yet that is where we find the longest living creatures. Maybe viruses help humans and animals deal with the effects of entropy?
How about Noah . . . between the occupants of the Ark, it is likely that most all the viruses were present but probably not all. Could that be a contributing factor to the reduction in the life spans of animals post flood?
Do all the viruses that existed in Eden still exist? I think it is likely they all do. Viruses are part of God’s creation and His creation is not easily put asunder.
It is important that Christians discover why God made viruses and show how they are good, and facilitate humans in living long healthy lives.
Viruses could be nothing more than a simple but very effective incentive plan for us to live abundantly, and when we are close to death, in our old age, viruses help push us on to the next place in a fitting manner. Or, viruses could be much more complicated in the scheme of life on earth in dealing with entropy.

“All” Christians, today, believe that part of God’s creation, i.e., viruses, are bad. That belief is an untenable position for the creationist/ Christian/ Christianity to survive in. That context for life has churches closed, while drugs and liquor thrive . . . where masked Christian leaders stand silently by while their millions of followers are cowering in fear over God’s good creation. It is tragic.
