I think that the plague bomb will do whatever damage is listed in addition to creating the plague.

The plagues are (unfortunately) hard-coded. There are only 5 possible levels of plagues. Medical Bays can have greater than level 5 ability because all they do is clear a plague of level Value1 or lower. So level 10 med bay works to clear a level 5 plague just the same as level 5 med bay does.
