Epidemiology Paper: Tuberculosis “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

(McMurray, 2007). “The agent in this study is Mycobacterium tuberculosis, an acid fast aerobic rod that reproduces slowly and is hypersensitive to heat and ultraviolet light. TB primarily affects the respiratory system; however, it can also affect the pericardium, lymph nodes, meninges, kidneys, intestines, bones, joints, and reproductive organs” (The Merck Manual, 2014). “The transmission of the Mycobacterium tuberculosis is spread from person to person via airborne droplets through actions such as coughing, talking and sneezing. The smaller the droplet, the longer it can stay in the air after the infected person has left the area. This causes an increase in the probability of inhalation by another individual. Passing TB from a family member or co-worker is more likely than a stranger in a store or on the streets”. (Reichler et. al, 2002). Mycobacterium tuberculosis, the infectious disease agent, is readily transmitted to susceptible humans, the host, through respiratory exposure in communal settings or public gatherings, the environment. Individuals with compromised immune systems, such as cancer, being on corticosteroid therapy, and HIV/AIDS, are at greatest risk for getting TB infection. Healthcare workers are continuously exposed to illnesses at the hospitals and long term care facilities, which puts them at risk for
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.
One of the most useful outcomes of studying epidemiology is learning how to evaluate critically the scientific literature (Aschengrau & Seage, 2008). Critical assessment of this literature is an important skill for public health professionals because the findings of epidemiologic research inform so many activities (Aschengrau & Seage, 2008). Munnoch et al. (2008) done epidemiological studies on S.Saintpaul infection occurred in Australia during October 2006 and found that cantaloupe production and processing practices pose a potential public health threat requiring regulatory and community education interventions. Based on main journal article written upon this subject, this article will analyse how epidemiological research has helped us
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.
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.
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 (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
Mycobacterium tuberculosis is uses the method of spread by small airborne droplets, which is called called droplet nuclei. It is produced by the coughing, sneezing, talking, or singing of a person with pulmonary or laryngeal tuberculosis (Nawrath et al.,2012). Hence, is frequently spread through aerosolizing of the bacterium. The foremost infection route of the bacterium is through the lungs; nonetheless, invasion of mucous membranes or breaks in the skin are also possible. Direct person to person transmission of M. tuberculosis occurs through exposure to airborne bacilli in the sputum of infected persons. Medical personnel are at risk of infection during autopsies, intubation, bronchoscopies or through dermal inoculation.
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.
“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.
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).
