from the article:

"A Delta flight from Atlanta, Georgia, to Barcelona, Spain, had to make a U-turn Friday after a passenger suffered a “medical issue” that turned out to be a case of severe diarrhea, according to multiple reports.

“My partner was on that flight!” a user commented on Twitter (now known as X). “It was pretty bad. It was dribbled down the aisle, smelled horrible. The vanilla-scented disinfectant used on it only made it smell like vanilla s---. "
