Measles.—This disease was dealt with very freely in the annual
report for 1908, and it is only necessary here to say that the
epidemic prevalence of that year was continued in 1909 up to the
middle of the year. 1,082 cases, nearly half of which occurred during
the first two months of the year, were reported by the School
Attendance Officers. 217 cases proved fatal, making an annual deathrate
of 0.69 per 1,000, the average death-rate during the 10 previous
years being 0.55 per 1,000. The southern part of the Borough was
most severely attacked, and as a means of checking the spread of the
disease, Canning Town Infants' School was closed from February 22nd
to March 8th.
