NON-NOTIFIABLE INFECTIONS.
MEASLES.
The incidence of measles was low throughout the year. For
the two years 1934 and 1935 the incidence followed that of London
which is a biennial beat, the years of heavy incidence being the
even ones.
In February a number of cases occurred in one school and a
smaller number in March in the same school. Otherwise there
were throughout the year only sporadic cases occurring in a few
schools and not spreading. Information of these is obtained from
the heads of the elementary schools. As their information is only
second hand from the diagnosis by a parent, the probability is
that many of these cases thought to be measles actually were not so.
German measles appeared in five separate schools in the
Christmas term but did not spread.
WHOOPING COUGH.
Whooping cough was prevalent in the earlier part of the year.
In January cases had occurred in eight schools, two being heavily
affected. The infection continued in most of these schools throughout
February and in March flared up in two previously lightly
infected schools, while a further five formerly free were attacked,
three heavily.
One of those which was first affected in March continued to
suffer each month until July. By the end of May most of those
attacked in March were free, but two, which started in April and
one in May, suffered quite heavily in June. A few scattered cases
were then reported for the rest of the year.
Whooping cough, which was responsible for three deaths in
the year 1934, accounted for five in 1935, three males of under two
years, one female of four years and one of six months.
Seven cases, all of children under five, were removed to
hospital for treatment.
CHICKEN-POX.
Chicken-pox was prevalent in the first quarter of the year,
but after April occurred only rarely except in one school which had
cases each month from February to October.
MUMPS.
Mumps was prevalent throughout the district in the months
of February to June, after which there was a marked reduction in
incidence, very few cases occurring from August to the end of the
year.
INFLUENZA.
Influenza appeared on the death certificates of 15 fatal cases.
Of these, 12 were evenly distributed throughout the first six months
of the year. The sexes were equally affected, and the ages of
the fatal cases ranged from 18 to 69.
