The people who do not want to follow preventive education are the most vulnerable to risk factors. To reduce the enormous global burden and long-term goal of better control of this communicable disease, there is a need for international surveillance.
The pathogen Mycobacterium tuberculosis is responsible for tuberculosis (TB). The person carrying the dormant tuberculosis germs is prone to tuberculosis, if the germs become active and multiply. ‘Latent TB infection’ (O’Donoghue, 2006), is the dormant state of infection in the body. Those with latent infection can easily transfer the disease to another person through contact. Ease of infection of this airborne disease is caused by exposure to infected droplet nuclei. It spreads through activities such as cough, sneeze, laugh, singing, etc. of the disease-carrying person. Approximate estimated figures show that the incidence of TB effects around 33% of world population. Reports show that about nine million people can suffer from tuberculosis disease in a year. Resource-limited countries have the highest prevalence of the disease and because it has not yet been completely uprooted, the chances of outbreak of the disease in other countries including the U.S. cannot be (LoBue, Sizemore, & Castro, 2009). In the “primary tuberculosis”, the patient can recover completely. This cured person still contains noninfectious, but live mycobacterium. This ‘primary inactive tuberculosis’ could follow one of the three paths in the future. It might remain inactive throughout the life span of the infected person, or it might develop into ‘active tuberculosis’ from its own infection, or the same person might get exposed to new infection called ‘reinfection tuberculosis’ (Jekel, Katz & Elmore, 2001).

...? EPID: Epidemiology B QUESTION 9 marks) A study aimed to assess the prevalence of anemia in children from 1 to 2 years in a country. Haemoglobin was measured by a Hemocue photometer and anaemia was defined as haemoglobin less than 8 g/100 mL blood. Duration of breastfeeding was determined by asking parents or carers. There were 4500 mothers or careers and their children who were asked to participate in the survey, of whom 457 refused to participate, and 243 had an incomplete questionnaire and/or test results. Among 1300 children breastfeed for less than 1 year, 520 had anaemia compared to 500 children with anaemia in the group of 2500 children breastfeed for one year or more (note: these are hypothetical figures only).

...? Understanding Risk and Causal Factors Attributing to Risk In Epidemiology The was concerned about the concept of relative risk. Risks in epidemiology help to compare disease or events outcome. The various types of risks that are analyzed in epidemiology are: Risk Difference: also known as excess risk is defined as the difference in rates of occurrence between exposed and non exposed groups in the population and is a useful measure of the extent of public health problem caused by the exposure.(Aherns et al,2005) Attributable fraction (exposed): also known as the etiological fraction is defined as the proportion of all cases that can be attributed to a particular exposure. One can...

...if there is untested clues in support of it, for demonstration if elimination of exposure decreases the incidence of the disease. The ninth facet is analogy. For demonstration, if a virus is shown to be oncogenic in animal investigations, we are more prone to accept that the human papilloma virus may be the origin of cervical cancerous infection in humans. In his term paper on association and causation, Bradford Hill remarks that "none of my nine viewpoints can convey indisputable clues for or against the cause-and-effect hypothesis and no one can be needed as a sine qua non". The dispute of considering causation is one of numerous fascinating facets of epidemiological research. References Evans, A.S. (1978): Am. J....

...Epidemiology Epidemiology Foodborne illness refers to the illness resulting from consumption of contaminated food, or foodthat with parasites, bacteria and viruses. Such illnesses result from consumption of beverages or food that contains disease causing pathogens. Most of the foodborne illnesses arise from improper handling, storage of preparation of food. Also, foodborne illnesses may result from toxins which affect the environment (Lindell & David, 2001). The consensus by the health community entails advocating for effective protection measures against the spread of foodborne diseases. This entails food safety to ensure monitoring of food to avoid causing foodborne diseases. Therefore, the research...

...Topic: Epidemiology Purpose of the study Wood dust is one of the common forms of occupational exposures worldwide andinvolves millions of workers. The dust particles differ in terms of size and chemical component depending on the type of tree. They also differ according to the type of operation performed on the wood which may include shattering wood cells during sanding operations that may result in the production of finer particle choices than in the case of chipping in sawing and milling industries. Although smoking is among the most common causes of lung cancer, environmental exposure also has a great contribution to the causes of lung cancer. Various studies have been performed in order to determine the risk involved...
