Throughout the century the scientists improved the BCG vaccine and today there are several different strains of the vaccine available. However, even today its full effects on the disease are unknown. The exploration of the effects of the vaccine, the best administration techniques, and who should be vaccinated continues. Throughout the Twentieth Century, Tuberculosis has impacted people around the world. While some countries see the impacts of tuberculosis less than others, the threat of this infectious disease looms across the horizon.
The body’s defenses against tuberculosis are effective but fail once the immune system becomes suppressed. Antibiotics can be used to help prevent tuberculosis, but tuberculosis quickly grows resistant to antibiotics. Much needed research is being done to find a way to fight off and prevent tuberculosis. 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.

In this paper I will state the importance of the registered nurses role in infection and control and also apply the findings from an evidence –based practice to patients with infectious and communicable disease. Breaking the Chain: The Patient with an Infectious Disease (Tuberculosis) Tuberculosis (TB) is one of the most known infectious diseases caused by a bacterium called Mycobacterium Tuberculosis that affects the lungs and can affect any age.

Tuberculosis is one of the major causes of death from many infectious diseases (3). Out of 9 million people who are infected with mycobacteria, about 2 million deaths occur from tuberculosis every year (3). Unfortunately, the prevalence of tuberculosis is in a continuous increase due to increased number of Human immunodeificnecy virus (HIV) patients, bacterial resistance to anti-tuberculous drugs, and growing number of recreational drug users (3). The pathogen responsible for bacterial infection, potentially causing tuberculosis, is mycobacterium tuberculosis (MTB) (2). Persons with adequate immune system can control the bacterial infection so mycobacteria remain dormant for a long time (11).
TB can spread to lymph nodes, through the bloodstream and throughout the body. It also affects a variety of animals. Although we think of tuberculosis as a disease that has been ‘cured’, at least in wealthy countries such as the United States, it is, in fact, still a very relevant problem. Even in a country where the majority of the populace does not consider it to be a huge issue, the U.S., “…more than 14,000 cases were reported in 2005” (Centers for Disease Control and Prevention 5). Also, most people seem to be ignorant of the fact that each year “…tuberculosis kills nearly 2 million people worldwide”(Mayo Clinic 1).

Tuberculosis can become resistant to most, if not all, of the drugs that are used to treat tuberculosis. Tuberculosis is a bacteria infection that affects many people over the world. Treatment for the disease helps people but it is limited. Vaccination is sought but, like treatment, is limited. Because of these limitations Tuberculosis spreads and kills easily.
Tuberculosis (TB) is a very prevalent, very contagious, and very deadly disease worldwide. According to the Centers for Disease Control, one third of the population is infected with TB. (Centers for Disease Control Data and statistics) While less common than it has ever been, tuberculosis has seen an upsurge in the last three decades directly related to the AIDS epidemic, but also as a result of the development of many multi-drug-resistant strains. This is of particular concern in developing nations hit hard by AIDS infections, but it is also evidenced in an upswing in the United States. (Nester, Anderson and Roberts) Because of the increase of cases both here and worldwide there has been a concerted effort to limit the number of new infections and to control the spread of it by managing the most at risk populations.
Primary infection 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.
