Typhoid, Fever.
There were 395 cases of typhoid fever notified in London in 1925 (52 weeks)
as compared with 410 in 1924 (53 weeks). The deaths in the calendar year
numbered 49 as against 53 in 1924. Of the cases admitted to the Metropolitan
Asylums Board hospitals the diagnosis of typhoid fever (including continued fever)
was not confirmed in 31.2 per cent., the corresponding percentage for 1924 being 25.7.
In 24 instances two or more than two cases were notified from one house, as
compared with 27 in 1924. Four of these 24 groups of cases were associated with
an outbreak in the Croydon area attributed to infected food, there being one instance
of 7 cases in one house, one of 5 cases and two of 4 cases. In the remaining 20 groups
there were four instances of 3 cases in one house, one of these being in the area of
an outbreak in Streatham attributed to infected milk.
