Tuberculosis :: Health, Diseases

tebibyte (TB) is an infection that can attack any part of the body, but it is usually found in the lungs (Huether, McCance, Brashers and Rote, 2008,). TB is an infection caused by a acid-fast bacillus also know as Mycobacterium tuberculosis (Huether et al. 2008) It is ane of the leading causes of death in Asia, China, Indian, Indonesia and Pakistan (Huether et al. 2008). These countries show that in most cases the relative incidence rate is highest in young adults, and are usually the result from re-infection in recent infections. The spread of TB is attributed to the emigration of infected people from high-prevalent countries, sum of money abuse, poverty, transmission in crowd places, and the lack of proper medical boot for the infected individuals (Huether et al. 2008).Tuberculosis is transmitted from person to person through airborne droplets, when a person that is infected with TB coughs, sneezes, talks, and/or sings letting small droplet to be released into the air(Bare , Smeltzer, Hinkle, and Cheever, 2008). TB cannot be spread through touching dyspnoeic objects, food, or drinks (Bare et al. 2008). The person must be in the same battleground an affected individual is in and inspirate the droplets to be affected. Once the bacillus is stimulate into the lungs, the bacilli start to multiply causing lung inflammation also known as nonspecific pneumontis (Huether et al. 2008). To cause an immune response the bacilli will travel through lymphatic system and choke lodged in the lymph nodes (Huether et al. 2008). Lung inflammation causes the activation of the dental macrophages and neutrophils (Huether et al. 2008). Granulomas, new tissue masses of operate and dead bacilli, are ring by macrophages, which mixture a protective wall. They then transform into a fibrous tissue mass, the central portion is called a ghon tubercle (Bare et al. 2008). The bacteriuml then necrotic, forming a cheesy mass, this mass may become calcified and form a collagenou s scar (Bare et al. 2008). At this point, the bacteria becomes dormant and in that location is no further progression of the active disease. The disease can become active again by re-infection or activation of the dormant bacteria (Bare et al. 2008).TB can be classified as latent or active (Bare et al. 2008). TB that is a latent is bacilli that are isolated with a tubercle can remain, dormant, causing no symptoms. Active TB occurs when live bacilli escape into the bronchi or if the immune system is weaken by diseases such(prenominal) as HIV or Cancer (Bare et al.
