In 18 of the weeks during the year no cases were notified,
one case each in 19 of the weeks, two cases each in 12 of the
weeks, three cases each in two of the weeks, and four cases in one
of the weeks. The maximum number of cases, viz.:—Four, was
notified in the first week of November.
Of the 54 cases notified 11 were not Enteric Fever, leaving
43 cases in which special enquiries were made as to the probable
cause of the disease.
In 14 of the cases the disease was probably contracted by
eating shell-fish, in six it was contracted outside the Borough
(one in Algiers, one in Margate, one in Boulogne, one in New
York, and two in other places), in nine the infection was contracted
from other cases, in four probably from watercress, four
occurred in the Prison, while in six no history of infection could
be ascertained.
With regard to the 14 cases caused by shell-fish, five were
from oysters, five from mussels, and four from winkles.
In the cases contracted outside the Borough, six in number,
it was impossible to ascertain the exact source of infection, but in
three of the cases it was probably from infected water supply.
