Infective Hepatitis.
Five mild cases were notified this year. There was no contact
between them and no further cases resulted from these.
Epidemic Enteritis.
There was an outbreak at the beginning of the year involving
31 children and the parents of three of these children. The patients
were quite ill for 2—3 days and a few relapsed after about 14 days.
All recovered and the school was kept under supervision until it
was clear of infection. No organism was isolated and the source
of the infection remained obscure.
Food Poisoning.
There were 31 cases notified as food poisoning during the year
and one unnotified case. In 14 cases the infection was found to be
due to Sal. Newport, in one case to Sal. Thompson. Eight of the
cases occurred in one family but investigation failed to reveal the
source of the infection. In another case, involving a baby of 9 months,
the dried milk was under supervision, and this baby infected his
mother with the same organism. A man and wife were both taken
ill after eating some ham on which was demonstrated a growth of
staphylococci. The Sal. Newport was isolated from a case who was
already an inpatient in hospital ; the source of infection was unknown.
From all the cases any suspicious articles of food were examined
bacteriologically but failed to produce any definite information about
the source of infection.
Tuberculosis.
The total number of new cases entered in the register during
the year was 81.
