INFECTIOUS DISEASE: TUBERCULOSIS
Tuberculosis is one of the leading infectious diseases around the world. Globally, infectious diseases like tuberculosis among others continue to be one of the leading causes of death in children, adolescents and of the leading causes in adults (WHO). The purpose of this article is to examine and discuss mostly the etiology of tuberculosis, as well as its cause and spread. To better understand the subject of tuberculosis as an infectious disease and the problem it poses throughout the world, the following questions would be answered: What are the factors important in the emergence and re-emergence of infectious diseases? How do sufferers and non-sufferers view tuberculosis? What is the impact of

Statistics also show that one out of seven humans die of tuberculosis.
In terms of etiology, the bacterium behind tuberculosis as discovered by Koch is a very stubborn one. In his work to determine the cause of tuberculosis he describes how the bacteria shows many distinct characteristics that make them so dynamic. They are rod-shaped, thin, only one-half as long as the diameter of hemoglobin but once in a while, they are able to get as long as the diameter of a cell and belong to a group of Bacilli. In addition, they are also described to possess a form and size that resembles that of the leprosy bacillus that exists in large numbers in everywhere they exist, usually in tissue cells and also outside cells. (Koch, 1882)
Mycobacterium tuberculosis is a small but very rapid growing bacterium that can only live in humans. Also, it is an aerobic bacterium (meaning that it needs oxygen to survive). This would explain why its complexes are always found in the upper sacs of the lungs.
For someone to actually develop Mycobacterium tuberculosis (Mtb) the bacteria would need to enter the body first and cause an infection and one of the ways for this to happen is through breathing in of Mtb infected air, thereby bringing the bacterium in contact with the lungs where it is able to thrive and grow.
Another way a person develops active Mtb is when the host’s immune system is not strong enough (as
Tuberculosis has been a persistent threat to the human race as far back as Hippocrates (c.460-c.370 BC). Globally, tuberculosis has infected millions during waves, often killing scores of people at a time, and then receding giving it an almost supernatural quality (Daniel, 2006). In recent history tuberculosis has been recorded in all corners of the world, and currently infects one third of the global population. In 2012, TB was responsible for killing 1.3 million people, making it the second largest fatal disease next to AIDS. The purpose of this paper is to describe tuberculosis, explain contributing factors, describe the disease in relation to the epidemiologic triangle, and finally
Tuberculosis is most of the feared and widespread that has harassed humans. Tuberculosis is a disease that affects the lungs and other organs too. This is a very serious disease that can cause death and the worse part is that this disease travels to one person to another. In the book, Know about Tuberculosis, a boy who has tuberculosis sneezed on another boy named Kevin who did not automatically catch tuberculosis, but the terms have taken root. According to the book, Know about Tuberculosis, “In the United States, about ten to fifteen million people are infected with this disease, but only ten percent of people are infected; however doctors assume that the battle against tuberculosis is increasing around the world.” Tuberculosis is among the major concerns for the World Health Organization due to its contagious nature.
Many people take breathing for granted, some never give it a second thought until a problem presents itself. Respiratory diseases affect millions of Americans as well as people from all over the world. Anyone can suffer from these disorders to include men, women, and children, with conditions ranging from mild, moderate, to chronic in nature. This paper will focus on one of the many respiratory disease called mycobacterium tuberculosis; more commonly referred to as TB.
Tuberculosis is a deadly disease that is now affecting our world and the people living in it in a horrible way. Due to many factors such as poverty, HIV/AIDS, and lack of health care, many third world and developing countries have been left very vulnerable to tuberculosis. It is affecting a large part of these countries and is leading them deeper into poverty and sickness. The effort to help these countries against tuberculosis has only been slightly effective against this widespread and destructive disease.
Tuberculosis is caused by the bacteria “Mycobacterium Tuberculosis” and is mainly causes infection of the lungs (WHO, 2016). Its mode of transmission is airborne, so it can be passed on by inhalation of airborne droplets which carrying the bacteria, when an infected patient coughs, sneezes, or spits the TB germs into the air (WHO, 1026). Among the symptoms of active TB are: cough with sputum and blood, chest pains, weakness, fever and night sweats (WHO, 2016). Most at risk to get the TB infection are people with weakened immune system such as people who are suffering from chronic diseases such as diabetes mellitus, severe kidney disease, silicosis and especially HIV infection (CDC, 2016). Children and Tobacco users are also at greater risk to fall ill with TB.
Tuberculosis (TB) is brought on by a bacterium called Mycobacterium tuberculosis. The microorganisms more often than not assault the lungs, however TB microbes can assault any part of the body, for example, the kidney, spine, and mind. Not everybody infected with TB microbes gets to be sick. Therefore, two TB-related conditions exist: latent TB infection (LTBI) and TB infection. If not treated legitimately, TB can be deadly (CDC, 2016). TB microbes are spread through the air starting with one individual then onto the next. The TB microorganisms are put into the air when someone with TB illness of the lungs or throat coughs, talks, or sings. Individuals adjacent may take in these microscopic organisms and also become ill (CDC, 2016). Individuals with TB are well on the way to spreading it to individuals they invest time with consistently. This incorporates relatives, companions, and coworkers or classmates.
Tuberculosis (Mycobacterium tuberculosis), also known as TB, is a disease spread by respiratory inhalation of droplets that contain the bacteria. Tuberculosis is an ancient disease that has been traced back at least 9000 years. In 1882, Dr. Robert Koch was the first physician to describe Mycobacterium tuberculosis as the germ responsible for tuberculosis. However, treatment that was evidenced based was not put into practice until the 20th century. It is estimated that 2 billion people around the world are infected with the TB bacteria. Approximately 5 to 10 percent of these infected people will actual develop active TB and experience the life-threatening symptoms of the disease. Tuberculosis
Tuberculosis, TB (tubercle bacillus) or MTB (mycobacterium tuberculosis) is a widespread, and in numerous cases fatal, communicable disease produced by a variety of forms of mycobacteria. The disease is distributed within the air when individuals who are infected with active TB infection sneeze, cough, or pass on breathing fluids throughout the air. Generally infections are asymptomatic, meaning they feel or show no symptoms, and dormant, but then again approximately one in ten dormant infections in the long run move on to the active disease. If left untouched, active TB is fatal to more than half of those infected.
Tuberculosis is most often caused by the mycobacteria Mycobacterium tuberculosis (Centers for Disease Control and Prevention, 2012). While tuberculosis can be caused by other bacterium, M. tuberculosis is the most common.
Tuberculosis (TB) is an infectious disease caused by mycobacterium tuberculosis, which most commonly attacks the lungs (2). Moreover, it makes the lungs unhealthy and infected. It is transmitted from one person to another via droplets. For example, from the throats and lungs of people infected with this active respiratory disease (2). In 2012, nearly nine million people around the
Tuberculosis or TB is a bacterial infection that spreads through the bloodstream and is commonly found in the lungs (webMD.com). This infection is highly contagious can spread rapidly through air, but remain undetected because the bacteria can live in the body in an inactive form (webMD.com). This disease originated in Russian prisons, where inmates would be malnourished, alcoholics, and smokers (Willumsen & Shinefield, 2001). Since the bacteria lives in the body in the inactive form, people who are exposed and may have TB never develops any symptoms (webMD.com). The bacterium becomes active when the immune system weakens (mayoclinic.org). The active form of TB can result in coughs, sneezes, and spits (mayoclinic.org).
Tuberculosis (TB) is a CDC (Centers for Disease Control) notifiable disease which is caused by an infectious bacterium that was discovered by a man named Robert Koch in 1882. This infectious bacterium that causes Tuberculosis is called Mycobacterium tuberculosis (Mtb), and is also known as Koch 's Bacillus. According to the National Institute of Allergy and Infectious Diseases (2015), Mtb is a small, slow-growing bacterium that can live only in people. It is not found in other animals, insects, soil, or other non-living things. Mtb is an aerobic bacterium, which means
Tuberculosis(TB) is a highly contagious disease that primarily affects the lungs, although it can also be found in other body parts. The disorder is caused by a bacteria called myocardial tuberculosis, and is mostly spread through the air when an infected person coughs. Many years ago, tuberculosis accounted for nearly 30% of deaths in the US. In the 1940’s and 50’s, however, its fatality rate dropped significantly due to antibiotics and vaccinations. Since the outbreak of AIDS, tuberculosis has increasingly been an issue again since people with the disease cannot fight off TB (Bontrager & Lampignano 2005, Basic TB Facts 2012).
For many people in the U.S. tuberculosis represents a disease process that one rarely sees. For this reason the reality of tuberculosis outside of the U.S. can easily be lost. CDC statistics report that approximately one third of the world 's population is infected with tuberculosis.1 This can be a sobering statistic for an individual wholly removed from the idea that tuberculosis, abbreviated TB, remains a prominent disease process throughout much of the world. The objective will be to provide not just an informative description of the disease, it 's etiology, clinical manifestations, treatments, and prognosis, but also to provide a reminder that tuberculosis retains a significant presence in the world despite the early
Tuberculosis is among the fatal diseases that are spread through the air. It’s contagious, meaning that it spreads from one infected individual to another, and at times it spreads very fast. In addition to being contagious, the disease is an opportunist infection as it takes advantage of those with weak defense mechanism, and especially the ones with terminal diseases like HIV and AIDS. Tuberculosis is therefore among the major concerns for the World Health Organization due to its contagious nature (World Health Organization 1).
