You say the changes to physical appearance happen randomly, periodically, and then give a specific set of times when they happen. It's a little disjointed, try slimming it down and having it be something like "approximately x times per day" or something like that.
I would break up that massive third paragraph, take some pruning shears to it and try to decide what is and isn't critical to what you're trying to say. Try to get the reader information about the infection sooner, maybe even make it the second or first paragraph. How quickly you give the reader some sort of understanding of what the main anomaly is can make or break an article.
The extremely brief and wooden interviews don't add a lot to the article, try refocusing on one that brings out some characterization in the doctors or the SCP. Overall, it doesn't really work that well for me but I like the image formatting you've made. Even if you scrap this I'd hang onto that.
Whether you like it or not, history is on our side. We will bury you!
