Attack Rates represent the number of cases occuring to
every 1,000 persons living at all ages. These rates are useful
for comparison with other Boroughs in regard to the incidence of
infectious diseases. (See Table 23).
The attack rate from all notifiable diseases for the whole
Borough during the year amounted to 5.88 per 1,000 of the
population, compared with 3.93 in 1904, and 6.09 in 1903.
The attack rate for the County of London was 7'01, compared
with 6.08 in 1904.
The attack rates for the Wards will be found in Table
22. It will be seen that Manor Ward, in Lee, had the greatest
number of cases in relation to its population, having an attack
rate of 11.10 per 1,000. The lowest attack rate was in
Sydenham Ward, 3.61 per 1,000.
