This year, twenty-eight per cent (1967 - fifty-one per cent) of
the infected immigrants contracted the disease within one year of
arrival in this country; thirty-five per cent (1967 - sixty-nine per
cent) contracted within three years of arrival. Persons born in the
Republic of Ireland were regarded as immigrants for this purpose.
INTERNATIONAL CERTIFICATES.
In order to prevent the spread of infectious diseases, certain
countries require that visitors should be vaccinated or inoculated
against specific diseases.
International certificates have been prescribed for smallpox,
cholera and yellow fever. When completed by a medical practitioner,
the certificate must be authenticated by the Medical Officer of Health.
During the year, 9,590 of these certificates were authenticated.
In addition, six special certificates were issued to travellers who
refused vaccination on medical or religious grounds.
REGULATIONS.
On 1st October, 1968, the Public Health (Infectious Diseases)
Regulations, 1968, came into force. These Regulations consolidate,
with amendments, all previous Regulations relating to the notification
and prevention of infectious disease except the Public Health
(Prevention of Tuberculosis) Regulations, 1925.
Certain infectious diseases were defined as notifiable diseases
by the Public Health Act, 1936, and all sections relating to the
prevention and notification of disease in that Act and in the Public
Health Act, 1961, applied automatically to them. Regulations made
under the Act of 1936 applied various of those sections, mainly
relative to notification, to other infectious diseases, and
authorised certain measures for preventing the spread of disease.
