Twelve persons, living within the Borough, attended a party,
one of the guests at which was subsequently found to be a case of
typhoid fever. The contacts were kept under surveillance for the
incubation period and specimens were taken, all of which proved
negative in result.
Nine contacts of other single cases of typhoid, all contracted
abroad, were also investigated, with the same result.
A case of sonne dysentery occurred in a ' half-way house' in
the Borough and all families living in the house were investigated.
It was found that only two persons in one family were affected and
they were quickly cleared.
Three children living in the Borough and attending a special
school in a neighbouring borough where there was an outbreak of
sonne dysentery, were also investigated. Two were cleared quickly
but in the remaining case it was found that four other children in
the family were also positive and the investigation continued for
nine weeks before all were cleared.
There was an outbreak of dysentery at a residential nursery
situated within the Borough, but belonging to the London Borough
of Brent. Specimens were taken from 27 children and 18 staff which
showed that six children and four of the staff were suffering from
sonne dysentery. All were fairly quickly cleared up, with the exception
of one child who remained positive for three months.
Two other outbreaks of diarrhoea and/or sickness were also
investigated, one in Cannizaro Old People's Home and one in Rowan
Secondary Girls' School. Both were short lived and in neither case
could a causative organism be isolated.
