Regulation 10
Where there is, or the medical officer suspects that there is, on board a ship on arrival or already in the district a person suffering from an infectious disease or tuberculosis, the medical officer may—
in the case of an infectious disease, cause such person to be removed from the ship and isolated or sent to a hospital or to some other suitable place approved for that purpose by the health authority, as may be appropriate; or, except as provided in regulation 31, the medical officer may, by notice in writing to the master, prohibit the removal of the person or his disembarking from the ship without the consent in writing of the medical officer;
in the case of tuberculosis, if the person disembarks, send information to that effect to the medical officer for the area in which the intended destination and address of the person is situated.
Where the Secretary of State is satisfied that a grave danger to public health exists by reason of infectious disease and notifies medical officers accordingly, the medical officer, if the Secretary of State so directs, shall require a person disembarking from a ship to state in writing his name and intended destination and address.
