Tuberculosis : An Infectious Disease

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.

Tuberculosis is a disease of an infectious nature caused by a bacterium known as mycobacterium tuberculosis. The disease spreads through the air. People with the disease can spread it to susceptible people through coughing, sneezing, talking or spitting. It mainly affects the lungs and other parts such as the lymph nodes and kidneys can also be affected. The symptoms for TB are fatigue, coughing, night sweats, weight loss and fever. One third of the population of the world is affected with mycobacterium tuberculosis. The rate of infection is estimated to be one person per second. About 14 million people in the world are infected with active tuberculosis. Drug resistant TB has been recorded to be a serious public health hazard in many countries. Resistant strains have developed making it difficult to treat the disease. TB has caused millions of death mainly in people living with HIV/AIDS ADDIN EN.CITE Ginsberg19981447(Ginsberg, 1998)1447144717Ginsberg, Ann M.The Tuberculosis Epidemic: Scientific Challenges and OpportunitiesPublic Health Reports (1974-)Public Health Reports (1974-)128-13611321998Association of Schools of Public Health00333549http://www.jstor.org/stable/4598234( HYPERLINK l "_ENREF_3" o "Ginsberg, 1998 #1447" Ginsberg, 1998). The World Health Organization came up with the DOTS (Directly Observed, Therapy, Short course) strategy. The approach involves diagnosing cases and treating patients with drugs for about 6-8

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.

According to the World Health Organization, tuberculosis (TB) is the number two killer worldwide due to a single infectious agent (WHO, 2017). In 2015, 10.4 million new cases have been identified and 1.8 million people have died from this disease (WHO, 2017). TB is caused by the bacteria Mycobacterium TB, and the majority of TB deaths occur in low and middle-income countries. This disease is curable and preventable, but the lack of access to proper healthcare and medication administration makes it a concern for the most of the world’s population. TB is an airborne disease that can transmit when an infected person coughs, sneezes, spits, laughs, or talks. The majority of TB cases can be cured when the right medications are available and

Tuberculosis (TB) is caused by a bacteria called Mycobacterium Tuberculosis, which normally affects the lungs, but it can also affect any part of the body, including the bones and the nervous system. The disease is spread easily through prolonged exposure to someone who has the illness, from their coughs and sneezes. For a healthy individual the body’s immune system kills the bacteria and prevents it from spreading in the body, which is known as ‘latent TB’. However, if the immune system fails to fight the bacteria, it can easily spread in the body. Symptoms will develop within a few weeks or months depending on the individual. This is known as an ‘active TB’. The symptoms are, constant coughing that brings up phlegm that may also contain blood, which lasts more than three weeks, combined with weight loss, tiredness and fatigue, loss of appetite and also fever. Without treatment, TB can cause major health problems and if its left untreated can even cause death (NHS 2016).

Tuberculosis is a disease caused by Mycobacterium tuberculosis that most commonly affects the lungs. The etiologic agent can be expelled from one infected person via a sneeze or a cough, and enter the air and then the body of another person, leading to another infected person (“Tuberculosis, 2012). According to “What is TB?” (n.d.), someone who has diagnosed tuberculosis but is not receiving any form of treatment can pass the disease to up to 15 people in on year. Treatment of TB is necessary, so if symptoms are ignored, an infected person could die. Prevalence of this disease is not as common in the United States as it is in other countries. In 2014, there were approximately 9,421 reported cases; trends show that TB prevalence continues to decreases each year. Of

Hi my name is Tyree Coleman and today I will inform you about a world known disease called Tuberculosis but most commonly known as TB. Tuberculosis is a infectious disease that mainly affects your lungs. Like many other diseases Tuberculosis is airborne is very easy to contract. This disease was first discovered in March 24, 1882 by a German physician and scientist named Robert Koch. Koch simply found traces of mycobacterium tuberculosis in cows, which is the bacterium that causes Tuberculosis. Many people are at risk of getting TB but may not even know it because of how quickly the disease can spread and not knowing enough information about it or not getting tested. The most common way you can get Tuberculosis is by being in constant

There are two stages of TB the infected patient goes through. The first stage is latent TB infection (LTBI), in this condition the bacteria can live in the body without making it sick, and the infected person can not spread the infection to others. Also, the body is able to fight the bacteria and stop them from growing by develops an immune response that controls the bacteria by walling it off inside the body. Because of the response of the immune system, the bacteria become dormant or asleep. However, if the person 's immune system

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 (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

However only a small portion of them actually become sick. Tuberculosis is caused by a type of bacterium called Mycobacterium tuberculosis. The condition is spread when a person with an active TB infection in their lungs coughs, sneezes or laughs, or other forced respiratory acts, and someone else inhales the expelled droplets of saliva, which can contain the TB bacteria. The bacteria then goes into the persons lungs, where one of two things can happen. The body detects the invasion and macrophages will engulf the mycobacteria and transport them to the lymph nodes where they are neutralised. If they are neutralised, the person then has latent tuberculosis. This means they are infected with the bacterium, but they don’t have active tuberculosis disease and they’re not sick. However, in 5% of cases the immune system is overwhelmed. The TB mycobacteria multiply and escape the macrophages and the person develops active tuberculosis. This often happens with young children, whose immune systems are not fully developed. In other cases, latent tuberculosis can wake up and become active TB. This can happen months later or even years later, especially in adults with weak immune systems. For example, people who are HIV-positive, people who’ve had organ transplants, or people who are undergoing chemotherapy. Once in the lungs, the bacteria may spread via the bloodstream or the lymphatic system to other parts of the body such as the lymph nodes, bones, joints, spinal cord, brain, the digestive system, the central nervous system, the liver or the heart. However that is rare and the condition is known as extrapulmonary TB. When someone has active TB in the lungs (most common) they start coughing and have difficulty breathing and suffer from chest pain. If the symptoms last for more than a few weeks, and are accompanied by fever, night sweats and weight loss, these are signs of tuberculosis. Mycobacterium

Tuberculosis is an airborne disease caused by a bacteria that goes by the name of Mycobacterium Tuberculosis. This bacteria is a rod-like shaped and can be very hard to treat, especially if it become multidrug-resistant. Many people have it and don’t even realize it because they have a certain type of TB called latent TB infection. This is when you have the tuberculosis bacteria in your body but it hasn’t started multiplying. There are different tests for it and different medications people can take to treat it. Young adults, HIV positive patients, smokers and any other patients that have illnesses that weaken their immune systems are the people most likely to get tuberculosis. It is said that HIV patients are 26 to 31 times more likely to become ill with TB.

Tuberculosis (TB) is a chronic bacterial infection that affects millions of people globally. It is a contagious disease that is spread through the air, and it usually affects the lungs. It is transmitted from person to person through droplets from the respiratory tract of those who are already infected with the disease. Some who are infected with the bacteria that causes TB often exhibit no symptoms, because their immune systems stop the bacteria from growing and multiplying. Those with compromised immune systems are more susceptible to developing the full blown disease which can cause symptoms that include coughing, spitting blood, chest pains, weakness, weight loss, and fever. Tuberculosis can be treated with a six to nine month course of a combination of antibiotics. If left untreated, TB will spread and can be fatal.

Humans are the only known carrier of Tuberculosis; it is spread from person to person through aerosol droplets released into the air when an infected person coughs, sneezes, speaks, or sings. The infection cannot be spread by: shaking someone’s hand, sharing food or drink, touching bed linens or toilet seats, sharing toothbrushes, or kissing (CDC, 2014). One cough from an infected individual can produce 3,000 infected droplets and it only takes ten bacilli to initiate an infection (Herchline, 2015). Since the disease is spread through the air, micro-epidemics are common in closed communities such as hospitals, nursing homes, prisons, submarines, and on transcontinental flights.

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).
