It usually affects the lungs but can be present anywhere in the body.

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. How Does Tuberculosis Develop?
Symptoms i The symptoms for tuberculosis are: (These symptoms are ranged from mild to dangerous) • feeling weak or sick all the time • 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
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 weren’t 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.

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.
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 i 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 that’s spreading rapidly amongst us..
