How do I tell my Intern their pumba stench is causing everyone around them to gag?

I have this intern that’s on rotation with me and it seems that they haven’t showered in who knows how many days.

At first I didn’t realize it was him. Naturally I spend a lot of time with him but more recently here, everywhere I go there’s this lingering stench until I noticed it would be whenever the intern would be in my vicinity. This plus their unkempt appearance made it click.

Like I have skipped showered on very very few days but I never let it get out of control to the point that there are flies following me around the hospital. Well leave patient rooms and the attending will request baths on some of the patients to the nurses.

Like the stench is so putrid that it’s causing patients discomfort with some asking, “Is that me that smells?”

I mean sometimes patients do be smelling but not like this intern does.

His smell has that “When I was a young warthog” energy

I just don’t wanna shatter his confidence or make him embarrassed. Idk how to approach it.
