SECTION X
OBSERVATIONS ON THE OCCURRENCE OF MALARIA ON SHIPS
Four cases of Malaria (all seamen) were reported on ships during the year under review. This
compares with nine cases in 1964.
One of the seamen was well on arrival, one was landed to Hospital at Gibraltar and two were
admitted to hospital on arrival in London.
A notice giving advice on the Chief Precautions and Treatment of Malaria is issued by the
Ministry of Transport and should be on board every British ship.
SECTION XI
MEASURES TAKEN AGAINST SHIPS INFECTED OR SUSPECTED OF PLAGUE
No ships infected with or suspected of plague arrived during the year.
The Fourth Schedule to the Public Health (Ships) Regulations, 1963, under the heading
"Additional measures in respect to the quarantinable diseases"—Part I—Plague, reads as
follows:—
"(1) The Medical Officer may—
(a) require any suspect on board to be disinfected and place him under surveillance, the
period of surveillance being reckoned from the date of arrival of the ship;
(b) require the disinfecting and, if necessary, disinfection of the baggage of any infected
person or suspect, and of any other article on board and any part of the ship which the
medical officer considers to be contaminated.
(2) If there is rodent plague on board, the medical officer shall require the ship to be deratted
in a manner to be determined by him, but without prejudice to the generality of this requirement
the following special provisions shall apply to any such deratting—
(a) the deratting shall be carried out as soon as the holds have been emptied;
(b) one or more preliminary derattings of a ship with the cargo in situ, or during its unloading,
may be carried out to prevent the escape of infected rodents;
(c) If the complete destruction of rodents cannot be secured because only part of the cargo
is due to be unloaded, a ship shall not be prevented from unloading that part, but the
medical officer may apply any measure which he considers necessary to prevent the
escape of infected rodents."
