Should there be a fine for people who claim not to have Covid symptoms and yet are found to have lied before boarding flights?

There was a passenger who died on a flight, and afterwards, his wife admitted he had Covid symptoms before boarding. Now everyone who was on that flight is dealing with possible exposure, including the medical personnel who helped him. On the news this morning, they gave other examples of passengers who were found to have lied about symptoms and boarded flights anyway.

Airlines use the honor system, asking passengers if they’ve had Covid symptoms prior to flying. Selfish passengers may lie, for obvious reasons (wanting their vacation, wanting to see family, etc.). Do you think there should be a more severe penalty, such as a fine, for those who lie about not being sick prior to traveling?
