NUMBERS
-
TB kills
almost 2 million people a year
-
The
breakdown in health services, the spread of HIV/AIDS,
and the
emergence of multi-drug resistant TB (MDR-TB) are contributing to the worsening
impact of the disease
- nearly
one billion people will be newly infected
- 200
million people will get sick
- 35
million people will die from TB
If control is
not further strengthened.
Every three
hours somebody get sick from TB in SCG

The
World Health Organization (WHO) estimates that between one and a half and two
million people die every year of tuberculosis.
The
estimates are that there is a TB death every minute.
We
have more cases globally now than we ever had in the history of mankind.
TB
is a disease caused by germs that can spread from one person to another. But
that’s not sufficient to make you sick with TB, you have to have in addition to
the germs things like poverty, poor economic situations, poor social conditions,
in order for TB to really spread very widely.
TB
was an enormous problem in Europe, it was the most frequent cause of deaths in
adults in all of Europe but particularly it touched northern and western Europe.
It was an enormous problem, it affected everybody. One in 200 people died of TB
every year. But in the big cities, for example, in the slum areas, the rate was
multiple times higher because of the terrible conditions that people lived in.
These conditions were mainly overcrowding that led to the spread of the germs
and under nutrition which affected their immune systems. Nowadays in Europe, TB
has almost disappeared in the European-born population, particularly in those
very countries that were most affected in the past, in the north of Europe and
in the west of Europe.
Most
of the TB patients today are people who come from other places where TB is more
common.
We
have more TB patients today than we had a 100 years ago, even though we have
made huge progress in what are now the rich countries which, then, had large
slums and poor areas. We’ve made big progress there but we now have more cases
globally now than we ever have had in the history of mankind.
That’s for several reasons. First of all, TB now rests mainly in the poor
countries, and in those poor countries, TB spreads easily because of the same
conditions that we saw in Europe a 100 years ago.
In
addition to that, population growth in poor countries is much greater than the
population growth in rich countries so, the number of TB cases grows because of
that.
The
problem of TB in India is of enormous proportions. The estimates are that there
is a TB death every minute. It’s enormous.
80%
of all the TB patients in the world live in 22 countries. The largest number of
patients in the world, in any single country, is in India, and that’s followed
by China, Indonesia, Pakistan, Bangladesh and then of course the countries of
Africa.
The
countries of Africa are emerging very rapidly and will become the centre of TB
in the future because of the association of TB with the HIV infection.
The
reason that people don’t get sick with TB when they get infected, or a large
proportion of them don’t get sick, is because their immune system keeps the
germs suppressed. When their immune system is knocked down, for example by HIV,
then those germs start to grow and TB spreads.
So
Africa is very heavily affected now by TB because of the HIV problem.
Today some 70-80% of TB patients in Africa, in many countries, have the HIV
infection.
The
WHO estimates that between one and a half and two million people die every year
of TB. And these are preventable deaths. Hardly anybody needs to die of TB
anymore.
TB
can develop resistance to the medications that are used if the medications are
not used properly. For example if the doctor gives the wrong prescription or if
the doctor does not observe the patient to swallow the medications, then the
germs can develop resistance to those medications and then the medications don’t
work any more.
There are 2 medications in particular that are the most powerful medications and
if a patient’s germs develop resistance to those 2 medications, it’s very
difficult to cure such patients. You can treat them, but the treatment instead
of being 6 months or 8 months, which is already difficult, becomes 18 or 24
months and many of the medications that are used cause side effects and they are
very difficult to take. So, it really complicates the issue and even if the
patient takes all the medications, the chance of succeeding to cure the patient
is very much diminished.
In
an ordinary patient, whose germs are susceptible to the medications, 85 – 90 95
% of them can be cured. In a patient whose germs are resistant to the 2
essential medications, 50 – 60 % can be cured so it’s a huge change. In addition
to that, the medications are tremendously expensive, they are at least 100 times
more expensive than the medications we use to treat most TB patients.
TB
is cured using medications because it’s an infectious disease caused by a germ.
These medications need to be of a high quality. In order to cure the patients,
they need to be given over a long period of time and they need to be observed to
be swallowed by the patient.
We
did a study for example of the quality of medications, selecting 10 medications
on the general market and 8 out of those 10 were not of good quality. In
addition to that, the patient has to take it over a long period of time so you
have to support the patient. It is not easy for the patient to come in every day
to a health service or to a health-care worker so the patient needs a lot of
support.
You
have to observe the swallowing of the medication, because we know that if you do
not observe the patient swallowing the medication, the germs can become
resistant to the medications.
Secondly, they have to be available and this is a big challenge in the poorest
places of the world where most of the TB patients live. Delivering medications
systematically, never running out of them is not an easy thing to do.
In
addition to that, the health service needs to be accessible, to their homes. If
you have to walk to get medical care as many people in poor countries have to
do, if you have to walk for 4 5 days, it’s very clearly difficult to access care
and diagnosis, particularly if you are ill.
In
addition to the health services being available, they have to be able to provide
the diagnosis of a good quality. The microscopic examination of the sputum is
the most important part so somebody needs to know how to prepare the slides and
the slides need to be of good quality.
We
need to track what we do, we need to have an accountability so that we’re sure
that we are actually delivering the services in a good way. That means we have
to record and report the activities and monitor them as they are being given.
These are the essential components of the DOTS strategy.
But
the most important part of it is first of all that the government is serious
about it. No single humanitarian or missionary organisation can solve the TB
problem, the government has to do it.
The
most important thing is that we have tools available today by which we can
expand rapidly, something known as the DOTS strategy. Unfortunately, only 30 %
of the world’s TB cases today have access to good treatment, namely DOTS, so we
have to expand this rapidly, double it or triple it.
At
the moment the control of the TB problem is only through DOTS which aims that 70
% of the patients in the community are to be detected and 85% of these patients
are to be cured.
The
International Union Against Tuberculosis and Lung Disease developed the DOTS
strategy and we’ve partnered with many countries in all regions of the world to
show that its actually feasible to do it even in the most difficult situations.
In
some areas of the world, we made real progress and we started to see TB
declining quite rapidly. For example in Peru over the last 10 yrs, we saw TB go
way down and this is what we had hoped for all over the world but now we see the
emergence of HIV infection and in those areas, until we control HIV infection,
we cannot hope to control TB. The main objective in those areas is to treat the
patients correctly, save their lives, make them healthier and prevent them from
getting drug resistant.
