What Is Tuberculosis?

• Tuberculosis is an air-bone disease that can
  spread when someone coughs, sneezes, or when
  somebody literally talks. It usually affects the
  lungs but can be present anywhere in the body.
  Each year 2 billion people or one third the
  earths population dies from tuberculosis.Tubercul
  osis can increase the infection if there is
  factors like poor air circulation or lack of
  fresh air breathing.

How Does Tuberculosis Develop?

• There are two possible ways a person can become
  sick with TB disease
• The first applies to a person who may have had
  been infected with TB but is perfectly healthy.
  The person can get infected again if they have a
  another disease such as HIV or cancer or they may
  get infected if they use drugs/alcohol.

• The other way it TB can develop, happens much
  more quickly. Sometimes when a person first
  breathes in the TB germs, the body is unable to
  protect itself against the disease. The germs
  then develop into active TB disease within weeks.

• (These symptoms are ranged from mild to
  dangerous)

• coughs that will not go away
• weight loss/loss of appetite
• fever/night sweats
• chest pain
• coughing up blood

Who Gets Tuberculosis?

• Anyone can get tuberculosis. Some people are at
  higher risks than others. The people who have
  more of a chance getting TB are
• People who share same breathing space
• Poor people/homeless people
• Prisoners
• Alcoholics or Drug users
• People with medical conditions (cancer, diabetes)
• Specially people with aids

7
Is Tuberculosis Curable?

• Fifty years ago, there was no cure or drugs for
  tuberculosis. If someone is given the wrong
  treatment, it would have been better if they
  werent given a treatment at all. When people get
  the wrong treatment, they wont be able to use any
  drugs at all for the disease. The treatment for
  tuberculosis is complex and is becoming even more
  complex because of HIV infection.

Primary tuberculosis pneumonia

• This is an uncommon type of TB as pneumonia is
  infectious. People who have it, have high fevers
  and productive coughs. It occurs most often in
  extremely young children and the elderly. This
  type is also found in HIV and Aids infected
  people.

In some cases, TB might spread though a chain
reaction. This picture is showing that TB is
infecting through chain reaction

The Three Stages

• There are three stages in the disease of
  tuberculosis. These three stages are identified
  from mild to extreme danger which is death. The
  first mild stage can get cured easily as long as
  the patient gets medication on time and takes
  good care. The second stage is more dangerous and
  the patient has to be really careful and that is
  were the symptoms should be considered. The third
  stage is extremely dangerous and there is no cure
  which means death. The third stage is the stage
  were nothing should go wrong and the patient will
  slowly begin to vomit blood and eventually die.

12
Who Discovered Tuberculosis?

• In 1882, Robert Koch discovered TB and soon he
  found out that it was caused by a microorganism
  Mycobacterium tuberculosis. After discovering
  that this disease was infectious, he started to
  consider treatments. Many treatments were tried
  but none were discovered until the year of 1943
  were the activity of streptomycin was discovered.

Conclusion

• This topic is not very common amongst us because
  we might not have experienced it personally or
  might not know people infected with this disease
  although it is very common worldwide. One third
  of the earths population is infected with
  tuberculosis (including minor infections) so I
  think that its important to learn about a common
  disease thats spreading rapidly amongst us..
