Tuberculosis is a highly infectious chronic disease cause by the TB BACILLI. It is primarily a respiratory disease common among malnourished individuals living in crowded areas. It often occurs in children of underdeveloped and developing countries in the form of primary complex especially after a bout of debilitating childhood disease as measles. INFECIOUS AGENTS- Mycobacterium tuberculosis and M. Africanum primarily from humans, and M. bovis primarily from cattle. Other mycobacteria occasionally produce disease clinically indistinguishable from tuberculosis; the etiologic agent can be identified only by culture of organisms. At present, there are 23 new strains of the TB bacilli found in the United States. Therefore, TB is no longer considered to be a disease of the past but of the pesent. MODE OF TRANSMISSION - Airborne droplet method through coughing, singing or sneezing. - Direct invasion through mucous membranes or breaks in the skin may occur, but is extremely rare. - Bovine tuberculosis from exposure to tuberculosis cattle, usually by ingestion of pasteurized milk or dairy product. Extrapulmonary tuberculosis, other than laryngeal, is generally not communicable, even if there is a draining sinus. PERIOD OF COMMUNICABILITY- as long as viable tubercle bacilli are being discharged in the sputum. Some untreated or inadequately treated patients may be sputum-positive intermittently for years. The degree of communicability depends on the number of he bacilli discharged, the virulence of the bacilli, adequacy of ventilation, exposure of the bacilli to sun or UV light and opportunities for their aerosolization by coughing, sneezing, talking or singing. Effecive antimicrobial chemotherapy usually reduces communicability to insignificant levels within days to a few weeks. Children with primarily tuberculosis are generally not infectious. Is there anyone who have this kind of disease hope i can give information and knowledge to some. Hope you can also add some information regarding to this disease.
