DISINFECTION.
Disinfection of bedding, clothing and premises is carried
out after removal to hospital or recovery of a home-nursed
case of a notifiable disease.
Bedding and clothing are removed from the infected
houses before disinfection of the house itself is begun and are
conveyed to the Disinfecting Station at the Isolation Hospital
for treatment in a Thresh Patent Current—Steam Disinfector.
Infected houses are disinfected with formalin diffused in
the form of a spray.

during the year:—
742 infected rooms and places disinfected.

returned to houses or libraries from which they were
issued and 25 were destroyed.
