Let's start with a virus becoming more transmissible....

If the virus kills 1% of its hosts and then becomes "more" transmissible it just means that more hosts get infected NOT that it is deadlier. It's not killing 2% or 20% more of infected hosts, it still has the same % of lethality.

As for satiated lifeforms that does NOT solely refer to life such as mammals, reptiles, invertebrates, etc.

"by becoming more deadly by having the ability to reduce the effectiveness of the virus thereby even infecting fully vaccinated individuals"~BC

Uhmm did you even read this? Becoming more deadly by a reduced effectiveness of a virus? WTF? So a less effective virus is more deadly? (Not even remotely true) viruses are genetically predisposed to spread and a deadlier virus kills more hosts limiting their ability to transmit to another host making that strain die out quicker, a virus that doesn't kill or incapacitate its host gets transmitted more often and becomes the dominant strain. Quick acting viruses like Ebola generally didn't spread far since the infected host became too ill to travel and died. That's why looking at the maps of Ebola outbreaks shows tight clusters and not large swaths. Plus to be fair I did say in simplistic terms and yet I still have to explain it to you.

Now about sarcasm and tact...

You have based your replies on a funny meme yet you have taken the meme as gospel and based your entire argument on refuting it.

As for the age issue I only replied to your insinuation that I was probably too young to know the tv show and possibly intimating a lack of experience.
