Why do you do this?
Anyhow, to make a case, I think that a person would have to know they have an infectious disease AND it must be proven that this persons actions caused infection of another (i.e. the “victim” didn’t pick it up somewhere else). More likely, an airport might be able to use the person’s diseased state as an excuse to breach the contract of allowing them on a plane or around other customers. This would probably develop as preemptive clauses in commercail contracts.
