It requires the notification to the medical officer of health of the district of every case in which a person is suffering from one of the diseases above mentioned.
The provisions as to notification are applied to every ship, vessel, boat, tent, van, shed or similar structure used for human habitation in like manner as nearly as may be as if it were a building.
