Tuberculosis Safety DVD Outline of first few minutes of presentation.
From the early 1800’s to the
middle of this century Tuberculosis killed more people in the United
States than any other infectious disease.
It used to be called the “White
Plague”.
The Development of effective
drug treatments in the 1950’s dramatically changed the situation.
By the late 1960’s TB
transmission was no longer considered to be a significant health problem.
It was projected that TB would
be eliminated from the United States
by 2010.
Unfortunately, over the last 10
years there has been a major resurgence of Tuberculosis.
In California TB cases have
increased over 50% in the last six years.
Across the country, 1 0-1 5
million people now carry “Latent TB”.
In the past several years, over
20,000 cases of “Latent TB” have become “Active” annually.
On a worldwide scale the problem
is even worse.
TB is the leading cause of death
by infectious
disease (killing over three
million people a year).
Approximately one-third of the
world’s population carries the TB bacteria.
Approximately eight million new
cases of TB occur each year.
Tuberculosis has once again
become a major health problem... one that we have to pay attention to.
We need to understand why cases
of Tuberculosis are on the rise.
People with HIV (AIDS) have
difficulty fighting TB bacteria.
IV drug abusers also have a
higher risk of developing TB (because they often have diseases such as AIDS
that weaken immune systems).
People immigrating from
countries with high levels of active TB have also contributed to its increase.
Another problem is that people with
active TB often end up in crowded living environments, where bacteria can
easily spread.
Prisons.
Homeless Shelters.
Care Facilities for the Elderly.
Other Institutional
Environments.
These factors have been made
worse because many facilities don’t have adequate Tuberculosis Control
Programs.
In recent years several
government agencies have moved to address the TB problem.
In 1990 the Centers for Disease
Control and Prevention (CDC) set up Guidelines for “Preventing the Transmission
of Tuberculosis”(which were revised in 1994 and again in 1 996).
The Occupational Safety and
Health Administration (OSHA) is also working on its own regulation.
Until their regulation is
completed, OSHA is enforcing the CDC Guidelines.
Both the CDC Guidelines and
drafts of OSHA’s TB regulations focus on the same major areas.
Employee Training.
A Written TB Control Plan.
Administrative Controls.
Engineering Controls.
Personal Protective Equipment.
Training, such as this program,
plays a major role in understanding these Guidelines by.
Helping to show you how to
protect yourself from possible infection.
Covering the nature, extent and
specific TB transmission hazards.
Discussing the incidence of TB
in the environments you work in.
Reviewing what steps you can
take to keep TB transmission down.
The CDC Guidelines also require
employers to create a Tuberculosis Control Plan.
Set up to limit exposure
situations.
To understand the Plan we need
to look at how TB is spread.
TB is a contagious disease,
which is caused by the Mycobacterium Tuberculosis.
The Bacterium is spread through
the air in microscopic droplets.
Droplets are generated whenever
an infected person coughs, sneezes or otherwise exhales.
Droplets can also be produced
during high hazard medical proceduresu such as:
Suctioning.
Intubation.
Administering aerosolized
medications.
The probability of TB infection
depends on the concentration of droplets in the air.
Concentrations can be especially
dangerous in enclosed or poorly ventilated spaces.
Tuberculosis infection occurs in
two stages. In the first stage:
The TB bacteria are inhaled and
begin to spread throughout the body.
A healthy immune system will surround
the bacteria and render it “inactive”.
This will usually occur within
two to ten weeks.
