US intelligence reports that researchers from the virology lab in Wuhan were hospitalized with an unknown illness in November of 2019, most notably before the "patient #0" was infected.

More research is necessary, but it's worth keeping your mind open to new evidence.

Are her social media accounts now empty shells run by the state to pretend she is still around?

Her history is spooky. And there is no evidence she is still alive.

Her wikipedia page seems sterile, and searching her name doesn't bring up anything about possible death.

In my own amateur opinion, either natural crossover or laboratory escape theories are plausible but we'll almost certainly never be able to prove it either way.
