International Certificates of Vaccination.
Travellers to most countries abroad have to produce evidence of recent vaccination against
certain prescribed diseases. For this purpose an international certificate of vaccination is used in
respect of smallpox, cholera and yellow fever. Methods of protection previously known as
"inoculation" are now described internationally as vaccination.
Under the terms of Ministry of Health circulars Nos. 60/48 and 20/52 the Medical Officer of Health
is required to authenticate the signatures on certificates issued by doctors practising within his district.
During the year, signatures on 5,815 of these certificates were authenticated.
Bacteriological Examinations.
Table 21, page 35, shows the number of specimens examined for the purposes of diagnosis and also
indicates the organisms in relation to which the examinations were made.
