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.
An estimated one third of the world 's population is infected with Mycobacterium tuberculosis. In 2012 there were 9,975 cases of TB reported and of those cases 28% where Hispanic or Latino. This respiratory disease is the most common in the lungs (World Health Organization, 2014). The brain which causes tuberculosis meningitis, genitourinary TB, gastrointestinal TB, tuberculosis lymphadenitis, cutaneous TB, uterus ovarian TB and Osteo- articular skeletal bone and joints are also parts of the body that are affected (Article base, 2008). Symptoms of TB are chills, fever, night sweats, hemoptysis, cough lasting more than 3 weeks, chest pains, and weight loss (Tuberculosis, 2014). Transmission of TB is through a sneeze, a cough, speaking, or singing in which the person has the
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).
Tuberculosis or TB, referred to by some as the White death due to the epidemic that arose in Europe that lasted two hundred years, is usually caused by in humans by a microorganism by substrains of Mycobacterium tuberculosis. It’s hard to determine the exact years in which TB first infected humans, but since the disease leaves traces on the bone in can be found in archeological record and it is believed to go all the way back to the B.C. era. Although it is hard to tell if the bone damage was truly from TB, there is research that shows that it has been around since the 17th and 18th centuries with a high number of incidences of TB, and in 1882 Dr. Robert Koch announced that his discovery of the causing factor of TB, which is Mycobacterium tuberculosis. A tuberculosis bacterium is spread through the air by an infected person speaking, coughing, or sneezing. Due to the fact the bacteria is protected by a waxy cell all, the body’s defense takes weeks to develop any kind of immunity and it allows the bacteria to exponentially multiply freely within the body. If TB it’s left untreated it will eat rapidly through many tissues, usually beginning with the lungs, lymph nodes, and kidneys. As the infection spreads to the lungs, it causes a cough and fluid between the chest wall and lungs, which leads to chest pains, severe shortness of breath, and potential heart failure. TB also infects bones and joints that can produce arthritis like pain and characteristic bone damage. Another possibility is that it may affect the fluid around the brain, causing meningitis, which can lead to fever, drowsiness, and eventually coma and death (Wingerson, 2009).
One of the first steps to treating Tuberculosis is identifying which form has developed in the body. The two forms that could progress in the body are latent Tuberculosis infection and active Tuberculosis infection (CDC, Morbidity and Mortality Weekly Reports). Latent Tuberculosis is the dormant form of the bacteria, meaning that it is inactive and doesn?t cause an infectious reaction in the body. Even if the latent form enters the body, treatment should be sought (CDC, Morbidity and Mortality Weekly Reports). Latent Tuberculosis can become active Tuberculosis easily though, especially if the immune system is compromised by another infection, like HIV (CDC, Morbidity and Mortality Weekly Reports). Active Tuberculosis infects the body immediately. Symptoms show in the body meaning the bacteria is effecting the cells of the body. Identifying the form is important because treatment is dependent upon it. Testing for TB involves a skin test, usually within seven work-days of contact with the bacteria. Without knowing what is in the body, the drugs won?t be as effective and might even cause drug-resistance.
Tb is spread trough the air and respiration. So when a person breathes in the air around them then they may not knowingly breath in one of the tuberculosis drop lets through there nose. The disease can also spread through the clothing and anything that the contaminated person has touched. If a person were to touch the clothing of an infected person they will most likely get the disease because it is so highly contagious. Many of the main people who are infected by tuberculosis are people who may already have been infected by another disease because their immune system is so week that makes them a main target for tuberculosis. People who may have a high risk at getting TB should avoid areas that have been infected, vaccinate themselves, get regular skin tests, take antibiotics if they know they will be around tuberculosis.
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 (TB) is an infection that can attack any part of the body, but it is normally 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 one 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 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, substance abuse, poverty, transmission in crowd places, and the lack of proper medical care for the infected individuals (Huether et al. 2008).
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 known as TB remains a leading cause of morbidity and mortality in the world, especially in developing countries. A combination of factors including high costs, limited resources and the poor performance of various diagnostic tests make the diagnosis of TB difficult in developing countries. According to Centers for Disease Control and Prevention (2014), one third of the world’s population is infected with tuberculosis. In 2012, nearly nine million people around the world become sick with tuberculosis disease, and there were around one point three million TB related deaths worldwide.
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.
Establish and contribute a shared voice for TB Controllers to go forward and promote a TB control and activities for elimination in the United States.
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.
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
What is Tuberculosis (TB)? Tuberculosis is an airborne bacterial infectious disease caused by bacteria/organism called Mycobacterium tuberculosis. TB is known to affect the lungs but can also affect other areas of the body such as kidney, spine and the brain. According the article Learn About Tuberculosis from the website American Lung Association, almost 2.5 billion people are infected with tuberculosis of which 9.6 million people worldwide have the active TB disease. Tuberculosis can be treated but if not, Tuberculosis can be fatal. TB is a very serious disease that needs medical attention and that is why people need to be informed about TB.
Infection rates of TB are high, especially when in frequent or close contact with individuals with active TB. One study estimates an infection rate of about 22% and a diagnosis with positive sputum smear is the strongest indicator of infectiousness. 19 However, contrary to common belief, sputum smear-negative patients are also infectious, with a study in San Francisco attributing 17% of transmissions to such cases. 20
