EPIDEMIOLOGY
Notification of Infectious Disease.
A total of 882 cases of infectious disease were notified during the year and
of these 154 were removed to hospital.
The number of notifications received was a little less than that for the
previous year. This appears to be due to the decrease in the number of notifications
received concerning children's infections.
Incidence of Infectious Disease
MEASLES.
There was a remarkable decrease in the number of cases of measles notified
which may, in part, be due to the campaign carried out last year advocating
vaccination against measles.
DYSENTERY.
A marked increase in the number of dysentery cases notified mainly in the
first quarter of the year, seemed to be paralleled in other London Boroughs.
Nearly all the 130 notificatons received were of sporadic cases.
FOOD POISONING.
There was also a sharp increase in the cases of food poisoning ascertained.
One outbreak accounted for 22 of the cases involved. Nine small family outbreaks
involved another 23 persons.
Of interest is the wide variety of phage typings identified by the Public
Health Laboratory which were as shown:
Salmonella Anatum. 1
Bredeney. 1
Bovis-Mordisicans. 1
Dublin 3
Enteritidis 12
