In neither of these cases of undetected Scarlet Fever did
the disease spread byond the infected house nor were inmates
there other than the children attacked.
In regard to return cases from the Infectious Hospital at
Bromley Common, the following facts were observed: —
There were sent to that hospital 107 patients with Scarlet
Fever, and who subsequently returned to their homes. All of
these patients were examined on their return by their medical
men, who gave certificates that these patients were free from
infection except in one instance—a child was returned to
hospital as being still infectious on account of peeling.
On making further enquiry 1 find that in 6 cases the
return home of the patient was followed by 6 cases of Scarlet
Fever. These cases of Scarlet Fever occurred after the following
intervals of time:—5 days, 13 days, 15 days, 17 days,.
49 days, and 56 days. Thus it would appear that 6 return
cases which were certified as healthy by their medical men,
were presumably capable of giving rise to the disease.
Scarlet Fever and Diphtheria.
There were 6 houses in various parts of the District at
which both Scarlet Fever and Diphtheria were notified.
In one case Scarlet Fever was notified, the premises were
disinfected, and 48 days after a case of diphtheria was
notified, and 7 days after that a fresh case of Scarlet Fever
occurred and 56 days after the return of the original case
of Scarlet Fever from the hospital. But the same thing happened
previously, for in 1907 a case of Scarlet Fever was
followed in 39 days by Diphtheria and in 89 days by Scarlet
F ever.
In another instance arising at the end of 1907, a case of
Scarlet Fever was notified, this was followed in 11 days after
the discharge of this patient from hospital by a case of
Diphtheria. Twenty-one days after the Diphtheria patient
was discharged from hospital a case of Scarlet Fever was
notified. Nine days after the removal of the Scarlet Fever
