to arrange for their family doctors to immunize Swabs were taken twice weekly, and on the third
swabbing another lady member of the staff was found to be infected and was sent to hospital A

had been discharged from hospital completely cured and the remainder of the staff had all been
immunised By then also, guinea-pig virulence tests had been reported negative No further
measures of isolation were found to be required.
TUBERCULOSIS
In 1935, the number of cases known to be suffering from Tuberculosis in Edmonton, was
about 600 It remained around this figure for the next two years and then rose to about 650.
In 1943 the number of cases rose again to 766 although the figures were lower in 1944/45, they
rose steadily from then on to a maximum of 1309 in 1954. There was a slight drop in 1955 to
1305, but since then the figures have been rising to 1325 in 1956 and 1344 in 1957.
As an infectious disease, Tuberculosis is more important than ever it was and more efforts
are needed to drain the pool of unknown infectors On the other hand, it has become much less
important as a cause of death, The deaths in 1957 were less than a fifth of those even in 1951
In fact, it is partly because of the falling death rate that the pool of Tuberculosis cases
continues to increase.

In addition 29 cases of Pulmonary Tuberculosis and 2 cases of Non Pulmonary Tuberculosis
previously notified in other areas, moved into Edmonton.
