Disinfection.
The work of disinfection last year was not so heavy as in
1902 as there were fewer cases of infectious disease notified,
epecially fewer cases of small-pox. Still, the work done was
considerable, as will be seen from the tables given below.
The total number of rooms disinfected was 1,616. In
most cases the disinfectant used was formic aldehyde, either
volatilized in an Alformant lamp or, more usually, applied
in solution as " formalin "by means of a spray. In verminous
rooms sulphur dioxide was used. After small-pox cases the
rooms were first disinfected by formic aldehyde and then the
walls were stripped of paper and washed down before and
after stripping with a solution of formalin. In all cases the
process of disinfection included the removal of all bedding,
clothing, and fabrics generally from the infected rooms, and
the disinfection of these articles by steam in the Equifex
machines at the Council's Disinfection Station. Infected
articles which would be destroyed by steam, such as boots,
feathers, etc., were disinfected by formic aldehyde in a specially
constructed zinc-lined chamber.
The following table shows the number of premises and
rooms disinfected during each month of 1903.
