It looks good so far to me, but should get a little attention before you put it up for general review. Specifically, there are a few parts that need tone edits. I was also struck by this part: "SCP-XXX infects human blood cells by absorbing the nutrients causing an almost anemic like response within the body. As the nutrients are absorbed, SCP-XXX will begin to replicate and fill the empty blood cells with a modified version of the human’s (from here known as SCP-XXX-1) antibodies, tricking the body into accepting the virus."
While I suppose that the chain of events described is plausible, a virus would not "infect … cells by absorbing the nutrients", though it might infect cells and cause them to absorb nutrients. Likewise creating foreign antibodies would not trick the immune system into accepting the virus, though it could evade the immune system and then produce modified antibodies as separate phenomena.
I do have to say that I liked the fact that diabetics are immune to the virus. It's one of those intriguing little details that adds verisimilitude to an article. If you would like any help cleaning up the science in the article I'm happy to lend a hand.
