ANALYSIS OF DEATHS AT ALL AGES IN RELATION TO
DISEASE GROUPS.
CLASS I.—Infective Diseases (99)
Small-Pox.—No deaths occurred from this disease.
Measles.—Measles was recorded as the cause of 7 deaths,
equal to a death rate of 0.04 per 1,000 of the population,
compared with 0.29 in 1908. It is not a notifiable disease,
consequently the case mortality cannot be obtained, but school
notifications show that the disease was much less prevalent last
year, than in 1908 (see page 59).
Scarlet Fever.—Sixteen deaths were notified in the
Borough, equal to a mortality rate of 0.10 per 1,000 of the
population, compared with 0.07 in 1908. The actual number of
cases notified amounted to 903, compared with 600 in 1908.
From this it will be seen that during the year under review,
more cases of Scarlet Fever existed. On considering the case
mortality it is found that of the 903 recorded cases l.77 per
cent, proved fatal, compared with 1.83 per cent. in 1908.
Diphtheria.—There were 21 deaths from Diphtheria,
giving a mortality rat3 for the Borough of 0.13 per 1,000 of the
population, compared with 0.28 in 1908. The number of
notifications amounted to 361, compared with 458 during 1908.
The case mortality was 5.82 per cent. of the actual cases,
compared with 9.61 per cent. in 1908, showing that not only was
this disease less prevalent but its variety less severe.
Whooping Cough.—Twenty deaths were attributed to
Whooping Cough during 1909, compared with 30 in 1908. All
the 20 deaths were of children under five years of age.
Enteric Fever.—There were only two fatal cases, equal to
a death rate of 0.01 per 1,000. The case mortality was equal
to 12.5 per cent. of the persons affected, compared with 12.9 per
cent. for the preceding year.
