The following points of interest may be noted : the rough
similarity of the three divisions of the borough in the number of cases ;
the fairly constant ratio of paralytic to non-paralytic cases (except to
some extent in non-epidemic years) ; the variations from year to year
in the sexes (but giving a small preponderance of boys over the total
period) ; the fact that only two persons over 45 years of age were
affected in the whole nine years, while approximately one-third were
under 5 and one-third were of school age ; and the total result that
about one in twenty dies, five in twenty have severe paralysis, five in
twenty have a mild paralysis and nine in twenty recover completely.
These figures are from statistics collected to some extent this year ;
some of the cases could not be traced, as indicated in the table.
