Should I write an addendum in this case?

In last May, I got a meningitis during final exam/paper period, so I couldn't work well on my final research papers in two classes.
For those two classes, I received B and B- while all other grades in my transcript are mostly in A range with a couple B+.
I don't want to get an unnecessary negative attention because these grades are not terribly bad, but I am bit worried because one of them are a senior capstone research course.
So I just want to hear about your opinions. If I need to write, I will make it just one short paragraph.
