So, the big issue here is that the idea isn't expressed very clearly and isn't that interesting. As I read it, it's a swarm of stem cells that sometimes looks like a blob or mouse, and then can sometimes get you pregnant with a fake zygote or kill you, depending on unclear circumstances. However, I'm not really sure if that's accurate or not, so feel free to correct me.
However, if that's an accurate description, there's not really much there there. Most objects nowadays have something that makes the reader care about them, whether that be an interesting picture, hints of a larger story, or descriptions that are novel and horrifying. Not every article needs these kinds of things, though; some can stand on their own concept. However, the idea itself needs to be interesting (my go-to example of this kind of article is SCP-1696). This concept is not interesting enough to carry the article. My suggestion would be to take a few hours and try to develop it some; as it is, it's just a blob that kills you.
Another major problem is that this not very well constructed. First of all, you don't define what SCP-XXXX-1 is, so half of the article involves talking about something that the reader has no way to visualize. Second, there is no reason to break everything up into all of these different collapsibles. I think that if you said everything in a few paragraphs, it would be far clearer. Similarly, your sentence structure makes it very difficult to understand what is going on, and generally takes much longer than necessary to say something which is not hugely interesting.
For example, I think that "In some cases, SCP-XXXX has entered a second dormant phase during the conversion division phase. In this second dormant phase the human subject will continue to live normally, unaware that they are a carrying vessel for SCP-XXXX" could be better expressed as "In █% of cases, SCP-XXXX will become dormant during the course of the conversion phase; hosts will not display any symptoms of SCP-XXXX infection until [ something ]. This phase can last up to ██ years, dependent on [ things ]."
This needs a lot of work, but could, with time and patience, be something interesting. Good luck!
