DIPHTHERIA.
During the year 179 cases were notified compared with 375 the previous year, the attack rate
being 1.3 per 1,000 of the population compared with 2.6. My anticipation that the incidence
of this disease was waning has been fully borne out. All cases were removed to hospital for
treatment; 10 deaths occurred, the fatality rate being 5.0 per cent., as compared with 3.2 per cent.,
last year. The age distribution of the cases is shown in Table 26(page 85).
DIPHTHERIA ANTITOXIN.
This is available to practitioners upon request at the Public Health Department. During
the year 44 issues, each of 8,000 units, were made. Since October, besides the usual packing
that has been in use for several years, a special packing with the serum already in a " syringe "
has been stocked and 9 issues were made.
