Tuberculosis is still a wide spread disease mostly in the poorer countries and continents such as: Asia, India and other third world countries. Although the BCG vaccine is said to protect children against tuberculosis its efficacy is doubtfull in some persons, because it is not repeated in time its protection is nule.The tubercle bacillus or Mycobacteria tuberculosis causes tuberculosis, it can be found everywhere around us, tapwarer, grass, mud, hay, rubber tubing. Usualy they do not cause human infection, when they do there are other factors that influence and create proper conditions such as: poor ventilation, dusty atmosphere, poor and low protein diet, migration, overcrowding.



For the same reasons that tuberculosis has always flourished unemployment, overcrowding, misery and migration. The recidivation of tuberculosis has been observed in those people and sometimes no reaction to the antitubeculous therapy or at least not the expected reaction. Famous artists, musicians and poets succumbed to tuberculosis, because they weren't paying proper attention to the disease and to its therapy.

Tuberculosis is not spread by clothes or bedding but one may take it from the air, sputum or any other close contact with a person carring the infection although it is not manifested. Mycobacteria are highly susceptible to ultra violet radiation and transmission rarely occurs out-of-doors in daylight. Mortality from tuberculosis had an increased rate among immigrants from the Indian subcontinent and Irish. Epidemic pandemies were observed during that period. And that's why it was absolutely imperios to develop a vaccine and antituberculous drugs.

If you have a healthy immune system, in most cases the infection will remain dormant without doing any obvious harm.

The lungs are the favourite place for the illness to strike, so pulmonary tuberculosis is the most obvious form. Tuberculosis can mimic many forms of disease and must always be considered if no firm diagnosis has been made.

The chest X-ray examination is the most important test. If there are changes in the lungs, a sample of sputum will be sent for microscopic examination and culture.

Alcoholics, HIV-positive individuals, some recent immigrants and healthcare workers and those with splitted family are at increased risk and usually develop tuberculosis.

Those people don't take their medication correspondently and do not follow the doctor's advice so their curing is improbable and even often the re-infection is present. The disease is most commonly found in places such as hostels for the homeless, prisons, and centres for immigrants.

After the tuberculosis bacteria have been inhaled they reach the lungs and, within approximately six weeks, a small infection appears that rarely gives any symptoms. This is called a primary infection. In some people the primary infection may not develop in the disease itself, but remain for their whole life primary infection.
