Erysipelas.
28 cases were notified, the youngest being in two
children under the age of one year. Five were admitted
to Rush Green Isolation Hospital and nine to other
hospitals. There was one death.
Cerebro-Spinal Meningitis.
There was one case of this disease notified, but no
deaths are attributed to this cause.
Acute Anterior Poliomyelitis and PolioEncephalitis.
During the year, 35 cases of acute poliomyelitis—
including two cases of polio-encephalitis—were notified.
One sporadic case appeared in April. In June, six
cases were reported, these marking the commencement
of a small epidemic which lasted until the end of
September. The outbreak thus showed the usual
seasonal prevalence for the warm months.
In only one instance was there a reliable history
that infection was spread directly from one patient
to another; in other instances it was presumably
transmitted by persons apparently healthy. There
was no reason to believe that the virus was conveyed by
foodstuffs or by insects, or that the disease was
associated with insanitary conditions.
Although individual natural immunity is high in
the first six months of life, there was one patient aged
three months. The largest proportion of cases occurred
between the ages of one and five years, with the highest
incidence in the second year of life. The average age of
those affected with acute anterior poliomeylitis was
four years and three months. The ages of the two cases of
polio-encephalitis were 10 years and 36 years
