Tuberculosis Among us today there are thousands of diseases out in the world, most are curable, some don't even have names. Well by the end of this paper you should learn about one more disease called Tuberculosis that will help you understand more about the infectious agents that threaten our lives today and how to control them, especially Tuberculosis. Tuberculosis is the increasingly spreading disease in the world and causes more deaths today then ever before. ( www. homepage.holowww.com) TB Global Emergency)) It kills 8,000 people a day that is 2-3 million people a year. It has surpassed the Aids community overall and is responsible for more deaths among the young and adults in the world today. ( www. homepage.holowww.com) TB Global Emergency)) To find out why Tuberculosis is causing all these problems you have to go to the source and find out what it is. Tuberculosis (TB), chronic or acute bacterial infection that primarily attacks the lungs. Tuberculosis is caused by the bacterium Mycobacterium tuberculosis. (AMA) Mycobacterium tuberculosis is a bacteria that is an obligate aerobe, rod shaped, acid fast, that has a characteristic mycolic acid cell wall. Generation time (time to create two bacteria from one) 18-24 hours Diagnostic test - PPD skin test, and x-rays. (Merck's Manual) Tuberculosis is a disease that can damage a person's lungs and causes serious illness. TB is usually transmitted by bacteria-carrying air droplets that are released when a person sick with TB coughs, sneezes, or speaks. Inhaled bacteria lodge in the lungs and multiply. Only 5 to 10 percent of those infected actually become sick. Once it is contracted, the disease can occur in a primary and a secondary stage. (AMA) When this occurs is causes the two stages of TB. The Primary TB produces no noticeable symptoms. Immune system cells ingest the TB bacteria and transport them to the lymph nodes where they may be destroyed or inhibited. TB is not contagious in the early stage. If the bacteria multiply, then active primary tuberculosis develops. Symptoms include coughing, night sweats, weight loss, and fever. If the bacteria are inhibited, the immune cells form a wall around inactive bacteria, producing a tubercle. As long as the immune system remains strong, the TB bacteria are inactive, and they may remain dormant for many years. If the immune system becomes weakened, the tubercle opens, and the infection may develop into secondary TB. (AMA) In secondary TB, bacteria destroy tissue in the lungs and may spread to the rest of the body. Fluid or air may collect between the lungs and the lining of the lungs, while tubercles continue to develop, destroying lung tissue. Coughing of blood or phlegm may occur. At this secondary stage, carriers of TB can infect others. (AMA) So how big of a problem is Tuberculosis? In 1993, the World health Organization (WHO) took an unprecedented step and declared tuberculosis a global emergency, so great was the concern about the modern TB epidemic. It is estimated that between now and 2020, nearly one billion more people will be newly infected, 200 million people will get sick, and 70 million will die from TB - if control is not strengthened. People with the active disease left untreated, will infect on average between 10 and 15 people in each year. Someone in the world is newly infected with TB every second. Nearly one percent of the world's population is infected with TB each year. (trc-chennai.org/dots.htm) Why isn't it such a big deal? Why, don't we hear about it in the United States everyday? The problem is that most of the world's population that is infected with the TB disease are stationed in the poor societies of the world. For instance the worlds biggest Tuberculosis outbreak is in poor countries like India, and small African countries. These are the countries that hold the most population and a disease outbreak in one of them will spread with no control cause they have no technology to help cure them or knowledge to stop the spreading of the deadly disease. TB kills 2 to 3 million people each year. TB accounts for more than one-quarter of all preventable adult deaths in developing countries. 7 to 8 million people around the world become sick with TB each year. Between 1993 and 1996 there was a 13 percent increase in TB cases worldwide. Nearly 2 million TB cases per year occur in sub-Saharan Africa. Nearly 3 million TB cases per year occur in Southeast Asia. Over a quarter of a million TB cases per year occur in
