PREVALENCE OP AND CONTROL OVER INFECTIOUS DISEASES
One thousand two hundred and seventy one cases of
infectious disease were notified during the year. Of
these six hundred and fifty seven were cases of Measles
which was epidemic from January to July, and four hundred
and forty one were cases of scarlet Fever, which sustained
a high prevalence throughout the year. There was a further

There were four sporadic cases of cerebro Spinal Fever,
and there was one case of Acute Anterior Poliomyelitis.

of higher virulence of the causative organism, the
streptococcus, which affected urban areas throughout the
country. In this Borough four hundred and forty one
cases'-were notified compared with one hundred and
sixty two during the previous year. The case rate was
6.17 per 1000 of copulation compared with 3.01 per 1000
of copulation for England and Wales. There was no
increase in the severity of the disease. Most of the
cases were very mild and there was no death. The
increased infectivity was demonstrated by a rapid
progression of cases in schools, a higher rate of residual
infection in cases discharged from hospital, and a larger

of the initial symptoms and the transient nature of the
rash tended to allay suspicion of infection and to delay
isolation of the patients. The spread of infection was
