looks to me like it’s the Chinese police that are investigating...so they could just execute her
“According to a statement from Beijing police, Ms Li took anti-fever medicine before boarding her plane and then failed to inform the flight attendants of her health condition with honesty.
Police are probing her on suspicion of preventing the control of infectious diseases.
A total of 59 people have been quarantined after coming into close contact with her, the police said.”
That's a very permanent "no fly."
Simple.
Just put her in a room with the 57 non-related people who are being quarantined because of her actions and let her explain to them how her needs were much more important that their inconvenience.
All being Chinese, I’m sure they will understand.
