In brief: Yes

This is a very good question.
It's fairly common for lactose intolerance that's genetically programmed to be unmasked after a bowel infection, and even if you're not going to be lactose-intolerant long-term, it can take a while for the disaccharidase molecules to be restored on the cells of the small intestine.
