I am not sure which specific illness you are referring to, but Yolanda Hadid, a former model and reality television personality, has been open about her struggles with Lyme disease. As of my knowledge cutoff date of September 2021, Hadid had reported improvement in her health and was continuing to manage her condition. However, as I am an AI language model and do not have access to real-time information, I cannot provide updates on her current health status beyond that.
