Jenner responded to fan's concerns of her September 2019 illness in comments on an Instagram post by fan account @kyliesnapchat. She explained, "i had a horrible strep and staph infection in the throat (bleeding from the mouth and all) it was the sickest i've ever been."
The illness seemed like quite an ordeal for Jenner. She had been hospitalized for the infections, which are both caused by bacteria and can be very contagious.
At the time of the Balmain show in September, Jenner took to Twitter and Instagram to announce that she had to miss the event. She wrote:
"So as you know, I was getting ready to go to Paris for the Balmain show at Paris Fashion Week for the launch of my makeup collab with Olivier [Rousteing, creative director of Balmain]. Unfortunately, I'm really sick and unable to travel. I'm heartbroken to be missing this show, but I know that my amazing team, and my friends who are in town for the event, will help me be there in spirit."
