Diphteria has been remarkably rare of late and seems to be almost
exterminated in this country. Last winter (1931—1932) a medical
lecturer in the Universitv of Iceland, Mr. Niels Dungal, made by means
of Schick's test a very instructive investigation into the immunitv of
school-children in Reykjavik against diphteria, and wrote an essay on
the matter, which appears as Part III. of this book. He gives an account
of the result of his investigation in the following survey:
Schick tests performed on 814 children from 8—14 years old in
Reykjavik gave the following results:
1) Of the whole number 81,9% reacted positively, 18,1% showing
negative reactions.
2) There is only a slight increase in negative reactions up to 12 years
age, followed by a sudden rise after finishing the llth year, ihe
number of negatives rising from 17,2% at 11 years to 37,5% at the
age of 13.
3) Diphtheria has been practically unknown in Reykjavik during the
last six years, and before that time rare for some years, a sudden rise
in 1920 and 1921 excepted.
4) It is suggested that the sudden rise in Schick negatives above
the age of 12 years may he explained hv this wave of diphtheria 10
years ago, when the age-groups now showing a higher percentage of
immunitv have just l>een 2 vears of age or more, i. e. beginning
to mingle more freely with other persons and accordingly more ex-
posed to the disease than younger children.
