deaths from TB, equivalent to 200 per 100,000.
|
|
1939
|
- Before
the invasion by Japan, statistical figures showed
that 4,443 died from TB, equivalent to 250 per
100,000
-

|
|
1939
- 1945
|
During
the wars, TB was a major killer disease due to
a number of factors: unstable social conditions,
poor nutrition, and serious overcrowding.
|
|
After
the war
|
TB
was the top cause of death. The influx of
refugees from Mainland China into Hong Kong further
aggravated the situation.
|
|
1940-1950
|
There
was great development in anti-TB drugs. The Hong
Kong Government liaised with The Hong Kong Anti-Tuberculosis
Association to develop plans for TB control services.
|
|
1949
|
The
Hong Kong Anti-Tuberculosis Association built
the Ruttonjee Sanatorium in the site of the previous
Navy Hospital, to provide services for TB patients.
|
|
1951
|
Streptomycin
was used for treatment of TB.
|
|
1952
|
BCG
vaccination was given to newborn babies and school
children.
|
|
1950-60's
|
It
was noted that about 3 quarters of the TB patients
did not complete the whole course of anti-TB treatment.
Hence, the use of supervised treatment (later
known as DOT, directly observed treatment) was
considered.
|
|
1962
|
Anti-TB
treatment regimens were used, including the use
of daily streptomycin (injection), para-aminosalicylic
acid, and isoniazid, followed by monthly supply
of PASINAH (para-aminosalicylic acid, and isoniazid)
tablets, for a total duration of 18 to 24 months.
|
|
1964
|
The
number of TB cases and death cases were 12,557
and 1,441 respectively.
|
|
1967
|
The
Government Chest Service formally liaised with
the British Medical Research Council in various
research projects.
|
|
1970
|
Fully
supervised treatment (DOT) was used on a service
basis. The number of new cases and deaths decreased
to 10,077 and 1,436 respectively.Since then, TB
gradually became under control and the figures
dropped gradually.
|
|
1979
|
Short
course service programme (6 months) was implemented
for treating TB patients.
|
|
1995
|
The
number of new cases of TB was 6,212.
|
|
1996-2000
|
There
has been an apparent trend of a slight rise in
the number of TB cases. Each year there were about
7,000 cases.
|
2001 |
TB
rate dropped to 108.0 per 100,000. |
|
2002
|
TB
rate dropped to 97.3 per 100,000 ( below 100 for
the first time).
