These two boys were given a further series of three injections
and, at a subsequent test three months later, were shown to be
negative.
46 boys were treated for the first time. 33 were positive and
13 negative to the test.
Of the 33 positive boys all have received three doses of
prophylactic (T.A.M.), 16 have come up for retest and are now
negative, and the remaining 17 await retest in 1932.
Fidelis Convent, Upper Norwood.
Diphtheria broke out in this convent in February of 1931.
Several cases were removed to the Borough Hospital and several
carriers were shown by swabbing to exist in the school. In spite
of these latter being also removed to the Isolation Hospital, cases
continued to arise among the children, and in March the authorities
were advised to have the whole of the children Schick tested
and the susceptible children immunised.
272 childrn were submitted to the test, 119 were positive and
153 negative.
All the 119 positive children received three doses of prophylactic
(T.A.M.) at fortnightly intervals and, at a subsequent
re-test, 73 were found to be negative and thus free from susceptibility.
Six children were found to be still positive at re-test and were
given three more doses of prophylactic; these, together with Is
other children, whose re-test was not due before the end of the
year, will be submitted to a further test in 1932.
The remaining 22 children, positive at the initial test, left
the school during the immunising process.
Twelve private cases were Schick tested, all children below
the age of ten years, none of whom had had diphtheria. 11 were
positive : of these 10 were immunised with three doses of prophylactic
and 8 subsequently underwent re-test and were found to ht
negative.
