But somehow, after SARS, the first bill drafted on this subject did include land transportation, because the purpose of it was to protect public health.
I would disagree with some of the phrases used in the presentation. People on buses do spend hours in close contact. People on trains do spend hours in close contact. While I know there are weird diseases coming from other continents, our own continent has also experienced certain diseases that could easily come across the border. It seems to me that what this mainly does is exclude land travellers from our neighbour to the south from any requirement of reporting.
