Regulation 13
The master of a ship shall, in accordance with paragraph (2) below, report
the occurrence on board ship before arrival of
the death of a person otherwise than as a result of an accident, or
illness where the person who is ill has or had a temperature of 38°C or greater which was accompanied by a rash, glandular swelling or jaundice, or where such temperature persisted for more than 48 hours, or
illness where the person has or had diarrhoea severe enough to interfere with work or normal activities;
the presence on board of a person who is suffering from an infectious disease or who has symptoms which may indicate the presence of an infectious disease;
any other circumstances on board which are likely to cause the spread of infectious disease; and
the presence of animals or captive birds, and the occurrence of mortality or sickness amongst such animals or birds.
For the purposes of the foregoing provisions the master shall—
if the ship is equipped with a suitable radio transmitting apparatus, send before arrival, either directly to the health authority or through an agent approved by them, a radio message complying with paragraph (3) of this regulation;
if the ship is not so equipped, notify the health authority, whenever practicable before arrival and otherwise immediately on arrival, of the presence on board of such infectious disease, symptoms or other similar circumstances.
Any radio message sent for the purpose of this regulation shall—
be sent so as to reach the health authority not more than twelve hours, and whenever practicable not less than four hours, before the expected arrival of the ship;
if it is in code, conform with Part VIII of the International Code of Signals as reproduced in Schedule 1, unless the health authority otherwise directs.
