SECTION F
INFECTIOUS DISEASES CONTROL
The contacts of two cases of enteric fever admitted to the Lennard
Hospital and Hither Green Hospital were investigated and proved
clear from infection.
The case admitted to Lennard Hospital was due to Salmonella
Paratyphoid "B" contracted on holiday either in France or the Costa
Brava region of Spain from which she returned by air. The organism
was isolated from the faeces and confirmed by Widal 1 in 320 for H
and O agglutination of blood.
The case admitted to Hither Green Hospital was confirmed as
Typhoid Fever by the isolation of Salmonella typhi from the faeces
and from three blood cultures. Widal test showed agglutination to
Salmonella typhi "H" 1 in 480. Vi agglutination was positive at
1 in 40.
Previous history showed that though he had received several
courses of TAB from 1941 to 1945 he contracted attacks of unexplained
fever in West Africa in 1941 and subsequently in 1950, 1952, 1954,
1957 and 1960. On discharge from hospital his Vi agglutination was
less than 1 in 5 after treatment with Chloramphenicol and Penbritin
and with the "O" and "H" agglutination confirmed that he would
not be a carrier.
Enquiries were made by Public Health Inspectors into three
incidents reported as due to food poisoning. One incident involved
five persons in a household who developed diarrhoea and vomiting
6-12 hours after the consumption of Rock Salmon which had been
covered with lemon juice and left to soak before frying. It was not
possible by examination to confirm the bacteriological cause of this
incident. Confirmation was not possible in the other two incidents
one of which occurred during a visit to Egypt and was notified 15 days
after onset and the other was notified 8 days after onset.
Visits were made to five households in which a case of Sonne
Dysentery had been confirmed and a total of 12 contacts were investigated
for freedom of infection.
Thirteen households from which a case of Scarlet Fever had been
notified were visited. All cases were mild and were being nursed at
home.
Arrangements have continued for the examination of faeces for
bact coli serotypes of admissions to St. Hilda's Nursery.
Twelve specimens were examined and no bact coli were isolated.
One specimen submitted was positive for Shigella Sonnei.
