Beat me to it... though I could also do one for Neutrophils at Work! as a COVID-19 advisory. This story is GREAT.

The Black version of Cells at Work swapped the gender of the red blood cell(female—male) and white blood cell(male—female), but this is a well-written fanfic whatsoever, good job!

I must say, this is quite well done so far! I like how you show that viruses aren't really alive, they just kind of... are. I also appreciate the disclaimer and the extra information at the end.

I was kind of confused, because the summary listed the cells from "Cells at Work: Black," but the characters described here seemed like AE-3803 and U-1146. I had to read it over again to realize that COVID infected the body from the main series, and then that body coughed it out, to infect another body (presumable from "Black").

Overall, this is nicely done. You're much braver than I am. I sort of wanted to write something relating to COVID, but I don't know enough about it to feel confident writing anything. (I actually did have something for a while, but as the pandemic stretched on, I felt that it was too simplistic and took it down.)

I appreciate the amount of research you did, and I think you'll do well! I'm interested in seeing how this goes! Keep it up! :D
