She could not ' disappear ' without an outcry from around the world. However the refusal of China to allow a proper investigation of her lab will always focus attention on her, and her reputation. Her work with hybrid bat coronaviruses by mixing and matching some existing ones, in order to study how they replicate in humans, is said to have been done in a level 2 lab.,as reported,  and not in the level 4 lab . This is looking like a possible leakage site by some , but until China allows scientists in to the lab, it's just supposition. It could be that if .and that's a big if, the virus escaped from the lab it would have been by mistake and nothing sinister. This could be nothing more than ego not wanting to admit a mistake. If it is a mistake ,and we don't know that , the world is paying for it big time.
