Introduction Tuberculosis (TB) is the most common disease worldwide which caused by Mycobacterium tuberculosis. With close to 10 million new cases per year, and a pool of two billion latently infected individuals, control efforts are struggling in many parts of the world (The bacteria usually attack the lungs, but they can also damage other parts of the body (Comas and Gagneux, 2009). It is important for a nurse to understand how tuberculosis develops, how to diagnosis, treatment, and prevent. Myobaterium tuberculosis is a nonmoving, slow-growing, acid-fast rod transmitted via aerosolization (airborne route). People who are most often infected are those having repeated close contact with an infectious person who has not yet been diagnosed with TB (Ignatavicius and Workman, 2006). Therefore, when a person with active TB coughs, sneeze, laughs, sings, or whistles, droplet become air borne and may be inhaled by others. Far more people are infected with the bacillus than actually develop active TB. The bacillus multiplies freely when it reaches a susceptible site (bronchi or alveoli). The majority of the bacilli are trapped in the upper parts of the airways where the mucus-secreting goblet cells exist. An exudative response occurs, causing a nonspecific pneumonitis (Ignatavicius and Workman, 2006). With the development of acquired immunity, further growth of bacilli is controlled in most initial lesions. Bacilli can also spread by erosion of the caseating lesions into the lung airways -and the host becomes infectious to others. Cell-mediated immunity develops 2 to 10 weeks after infection and is manifested by a positive reaction to a tuberculin test. Skin testing for tuberculosis is useful test to detect. According to Universi... ... middle of paper ... ...te. Other symptoms should be considered to diagnosis TB, such as weight loss, anorexia, shortness of breath. According to CDC (2011), TB is not spead by sharing food or drink, shaking someone's hand, touching bed linens or toilet seats, sharing toothbrushes, or kissing. As a nurse, he/she needs to instruct the patient with active TB to cover the mouth and nose when coughing or sneezing, to place used tissues in plastic bags, and to wear a mask when in contact with crowds until the drugs suppress infection (Ignatavicius and Workman, 2006). Conclusion It is important for us to know the pathology of tuberculosis because is a threatening disease that kills million people each year. Therefore, early sign and symptom detection will help people to treat properly and to prevent spread TB disease to others. The use of combination drugs are most effectiveness therapy.
The lungs are the organs responsible for the exchange of oxygen and carbon dioxide between the air and the blood via the bronchial tree. Tuberculosis (TB) is a granulomatous disease which primarily infects the lungs but can spread to other vital organs. It is caused by bacteria called Myobacterium tuberculosis and if went untreated, can be fatal. TB is spread through the air when a person who is infected coughs or sneezes and a person nearby breathes the air. People who have been diagnosed with HIV are at a higher risk of contracting TB since their immune systems are weaker. Other risk factors include having diabetes, use of alcohol and drugs. In this paper I will discuss the normal functions and anatomy of the lungs and how TB effects these functions.
A low-grade fever, weight loss, lethargy, night sweats, respiratory congestion, cough, and hemoptysis, are symptoms indicative of Tuberculosis. A positive skin test, abnormal chest x-ray and a positive sputum culture are indicators of Tuberculosis. Tuberculosis is transmitted by inhalation of respiratory droplets containing bacteria. This excerpt depicts tuberculosis and its history and prevalence.
Tuberculosis is a contagious airborne disease that affects the lungs of humans and some animals i.e. cattle. If tuberculosis is left untreated and allowed to spread, it can then also affect the brain, kidneys, spine or other organ systems. As tuberculosis strikes the lungs a hole can develop which can cause an accumulation of air or fluid between the chest wall and lungs. This causes one of many tuberculosis symptoms: chest pain, and shortness of breath. (See fig.2) Infections can erode a blood vessel and the patient can bleed to death, or they can slowly suffocate as lungs become filled with tubercles.4
Tuberculosis as (TB) is caused by Mycobacterium tuberculosis. It is slow growing bacteria that thrive in areas of the body that are rich in blood and oxygen, such as the lungs. Tuberculosis develops when Mycobacterium tuberculosis bacteria are inhaled into the lungs. The infection usually stays in the lungs, but the bacteria can travel through the bloodstream to other parts of the body.
Active TB patients are IGRA positive and are symptomatic. The granuloma model: macrophages get infected in non-activated macrophages, necrosis occurs, lymphocytes also activate macrophages. MTB continue to grow and spread. The tubercles bexome liuqified and extracellular bacterial growth ensue, releases liquifed caseous material into the bronchiole causes causing and this can be transmitted tooter people.
Tuberculosis is disease caused by a bacterium called Mycobacterium tuberculosis. Usually bacteria attacks lungs but TB bacteria can attack any parts of the body such as brain, kidney, and spine. It can spread through the lymph node and blood stream to any organ. Usually it is seen in the lungs. If it is not treated accordingly, it can be deadly. One of the leading causes of death in the United States was tuberculosis. Everyone who infected with TB bacteria not get sick. There are two TB conditions stand. They are latent TB infection and TB disease. In latent TB infection, people do not get sick but TB bacteria can live in you. People with latent TB infection cannot spread the bacteria to others nor are they infectious. If the bacteria is active and multiply, the person has TB disease. If a person has TB disease, their immune system cannot stop the bacteria become active. People with TB disease get sick and they are able to spread the bacteria to others.
Healthcare workers working in close proximity with infected patients are required to take various standard precautions. These standard precautions include hand hygiene, wearing personal protective equipment, appropriate management of sharps and waste and appropriate decontamination of the working environment. For their own protection, a healthcare worker must assume that all blood, body fluids and secretions from patients are potentially hazardous and my cause infection. If the appropriate precautions are taken, healthcare workers can prevent becoming infected with TB themselves (HSE/HSPC, 2010).
Education can be a powerful weapon in fighting tuberculosis in the United States also around the world. Today, it is encouraging how so many people know how TB contracts human and what cause drug resistant effects among those who are under TB treatment.
Tuberculosis is a highly contagious disease that is spread through the air from one person to another causing it to be an airborne disease. When a person with tuberculosis coughs or sneezes the bacteria fly into the air. Anyone around a person with tuberculosis who is not wearing proper personal protective equipment, and breathes in the bacteria will then catch tuberculosis. Tuberculosis mainly affects the lungs, but it can
Public health nurse has an important role to the community by providing health services to many people who are not able to afford medical services. In the case scenario provided, nurse Jill’s role is to screen tuberculosis and to track people who have tuberculosis in a high risk population (homeless population). According to Center for Disease and Prevention (2012), tuberculosis is caused by Myobacterium tuberculosis and it is transmitted through the air from one person to another via cough, sneezes, and speaking.
Tuberculosis or TB is an airborn infection caused by inhaled droplets that contain mycobacterium tuberculosis. When infected, the body will initiate a cell-mediated hypersensitivity response which leads to formation of lesion or cavity and positive reaction to tuberculin skin test (Kaufman, 2011). People who have been infected with mycobacteria will have a positive skin test, but only ones who have active TB will show signs and symtoms. Basic signs and symptoms include low grade fever, cough with hemoptysis, and tachypnea. They may also show pleuristic chest pain, dyspnea, progressive weight loss, fatigue and malaise (Porth, 2011).

Primary tuberculosis is the initial infection of the host, usually being mild and asymptomatic. A healthy person recently infected with the mycobacterium may exhibit flu-like symptoms and has no reason to suspect tuberculosis. Left untreated, the bacilli infect and multiply within pulmonary alveolar macrophages, migrating to the hilar lymph nodes. An immune response is exhibited by the T-helper cells, and inflammation develops at multiple sites. A person may test positive in the tuberculin skin test at this point, and a chest x-ray may shows opacities in the lungs.
In the year 1882, Robert Koch identified Mycobacterium tuberculosis as the causative agent of tuberculosis (TB). According to Mandal, Mycobacterium tuberculosis existed about 15,000 to 20,000 years ago. It has also been proved that Europeans contributed a a very large extension in the spead of TB around the word (Jaeger et al., 2012). Tuberculosis reached its peak in 18th century and resulted in large number of deaths. At the time, TB was rampant, causing one-seventh of all cell deaths in Europe and one-third of deaths among productive young adults. Today TB remains a global health problem of enormous dimension. It has been reported by Centre for disease Control and Prevention that in the year 2011, about 1.4 million people died with TB all around the world and about 9 million people became sick with TB (CDC | TB | Data and Statistics").
Tuberculosis has plagued mankind for a long time. This disease, which was previously believed to be eradicated, has once again shown up and begun attacking the lives of many humans. Tuberculosis infects a third of the population and kills a fraction of them. Many approaches have been used including different varieties of infection control, bodily defenses, and treatments to try to protect humans from tuberculosis. The best way to prevent tuberculosis infections is to contain the source of tuberculosis. The most common source of tuberculosis infection is from infected humans. By diagnosing, containing, and treating people with latent tuberculosis before they get active, contagious tuberculosis, tuberculosis can be quickly contained. Once someone has been diagnosed with TB, they should be placed under isolation.
