TABLE No. 28 Cases of Diphtheria during the Years 1926 and 1927
| Year. | Cases Notified. | Percentage of Removals | Deaths | Case Fatality Rate. | Percentage of cases of School age (3-13 years). | Month of greatest prevalence. | Bacterioscopic Diagnosis, Lister Institute. | ||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| No. of Specimens submitted | Positive | Percentage Positive. | Negative. | Percentage Negative. | |||||||
| 1926 | 207 | 98 | 6 | 2.9 | 55 | Mar. | 317 | 33 | 10.4 | 284 | 89.6 |
| 1927 | 127 | 96 | 4 | 3.1 | 56 | Nov. | 418 | 39 | 9.3 | 379 | 90.7 |
It will be observed that the number of cases notified in 1927 was
fairly low, and that the percentage of removals to the M.A.B. Hospitals
was high. On the other hand, the case fatality rate was somewhat higher
than that for 1926.
Information was received from the M.A.B. that 9 of the cases sent
to Hospital in the course of the year proved not to be suffering from
diphtheria.
Of the 127 cases notified, 43 occurred in Stanley Ward, 39 in Church
Ward, 13 in Cheyne Ward, 19 in Hans Town Ward, and 13 in Royal
Hospital Ward.
During the year several cases were notified from the Infants' Ward
of a Hospital in the Borough. A thorough examination of the drainage
system of the Hospital was thereupon carried out and such defects as
were found to exist were rectified by the Board of Management. Investigation
for " carrier " cases was also made.
The following table shows the average annual case rate, case fatality
rate, and percentage of cases removed to hospital in each of the
quinquennial periods since 1911.
