World Health Organization has called Tuberculosis the second greatest killer caused by a single infectious agent after HIV and AIDS, it has been declared as a public health crisis which is contagious, deadly and with grave consequences for those affected. Tuberculosis is found more often in third world and developing countries. More than 80% of people in Asia and Africa test positive for TB. Early in the 19th century many deaths have been recorded in Europe, where as in the United States it has been well controlled until recent

TB bacterium can also infect different parts of the body like the spine, kidney, cervix, joints, bones and brain but is mostly found in the lungs. TB is an airborne disease and can be spread when an infected person coughs, sneezes, sings or talks and others get infected when they inhale the germs. Tuberculosis can be found in about one thirds of the world’s population and out of that only a small portion will become sick with TB. People that have weakened immune systems are at a much higher risk of getting sick from TB. People with AIDS OR HIV have an increased chance of developing active TB the same goes for young children and the elderly. CAUSES, SYMPTOMS, COMPLICATIONS, AND TREATMENT.
The causes generally fall in two categories infected with the TB bacteria, the first one are those people who immigrate from countries with high TB rates, homeless persons, employees of TB facilities, people living at shelters, hospitals and children less than 5 who had a positive TB test. TB can infect any part of the body but it usually infects the lungs. Classic symptoms include chills, fever, night sweats, cough, fatigue, cough and sometimes the coughing up of blood. Tuberculosis can be fatal if not treated; it can also spread to other parts of the body through the blood stream. TB can cause joint damage, spinal pain, meningitis, liver, kidney problems, cardiac tapenade, and visual
With the close proximity infection range TB is known for completes the remainder of the epidemiologic triangle. Overcrowded environments are the coal to the fire of this transmittable disease with outbreaks capable of occurring, infection hundreds. Common symptoms of this active form of tuberculosis include: weight loss, coughing, fatigue, fever, night sweats, chills, and loss of appetite (MayoClinic, 2014). The Mayo Clinic also states that it is believed that 2 billion (one third) of the world population is living with Latent TB (2014). This emphasizes the need for public health and community involvement in order to completely abolish this disease from our planet.
“Tuberculosis (TB), a multisystem disease with myriad presentations and manifestations, is the most common cause of infectious disease–related mortality worldwide. Although TB rates are decreasing in the United States, the disease is becoming more common in many parts of the world. In addition, the prevalence of drug-resistant TB is increasing worldwide. TB is caused by M tuberculosis, a slow-growing obligate aerobe and a facultative intracellular parasite. The organism grows in parallel groups called cords (as seen in the image below). It retains many
Epidemiology is viewed as the fundamental science of public health and is key in endorsing optimal health in the community as a whole (Stanhope & Lancaster, 2008). Epidemiologic study and practice continues to reform public health and endeavors to prevent disease in communities across the world. This paper will address through descriptive epidemiology, the rising disease of obesity and will focus on the teen and adolescent population of the United States. This paper will also define and discuss the purpose of epidemiology, the methods of the science, the epidemiological triangle, and the relationship of the disease to various levels of prevention.
This paper will discuss the communicable disease influenza. It will discuss the causes, symptoms, and treatments, as well as the demographics of interest. It will also discuss the determinants of health and how these factors contribute to the development of influenza. Included in this paper will be information on host, agent, and environmental factors. Lastly it will explain the role of the community health nurse in caring for those affected with influenza and the role they play in education and prevention.
Epidemiology is the study of diseases and informs the public about the health epidemics and new standards put in place. They usually work in laboratories, businesses, and offices where they work on discovering many diseases and conducting research while also finding cures to new diseases. In order to become an epidemiologist, I will have undergo through 4 year as an undergraduate and obtain a Masters in Biology or Public Health. In high school, it is recommended for me take Biology, Chemistry or to have some type of science background in order to help me get best prepared. In this paper I will discuss the history of epidemiology, the pathway to get to this career, and why this job/career will be the best fit for me.
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.
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 is a bacterial infection that can be spread in the lungs, lymph nodes, and bloodstream and to any part of an organ in the body. They are two types of tuberculosis which, is active and
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 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.
Tuberculosis does show any different physical signs than regular tuberculosis. Both forms of tuberculosis show coughing for more than 3 weeks, coughing up blood or mucus, chest pain, fatigue/weakness, weight loss and loss of appetite, fever, and chills (1). Tuberculosis is easily caught by a new patient because the air that is contaminated by a carrier of the bacteria who has been in the room for a rather long time. Meaning if a person visits the carrier and goes into the carrier’s bedroom for an extended length of time, then that person could possibly contract tuberculosis. Not only is immediate contact a key factor in developing tuberculosis, health, where a person lives, and if that person developed tuberculosis in the past. These factors all accumulate and help in the spread of the disease from person to person.
TB does not just affect the lungs, contrary to popular belief. TB can affect your kidneys, spine or brain. TB in other body parts will result in issues occurring with the afflicted area. There are also two different kinds of TB. The first kind, which is estimated to be in two billion people, is called latent TB. Latent TB is TB that exists in your body that is in an inactive state, this inactive state of TB is harmless. This inactive state causes no symptoms and is not contagious. You still are
“Epidemiology is the study of the distribution and determinants of health-related states or events (including disease), and the application of this study to the control of diseases and other health problems (WHO, 2015)”. “Various methods can be used to carry out epidemiological investigations: surveillance and descriptive studies can be used to study distribution; analytical studies are used to study determinants (WHO, 2015)”.This paper discusses about epidemiology of HIV infection, including factors that contribute the development of the disease, epidemiologic triangle, role of community health nurse and the national organization that address the communicable disease.
The disease can be transmitted mainly through the air, but there are other means of being infected with TB. Alcohol and drug abuse are some of the popular means in which infection can occur and since the drugs weaken the immune system, the spread of the ailment can be rather fast. Terminal diseases like HIV and cancer reduce the immune system and this promotes propagation of the disease into an individual’s body system.
