Hep B and Dq1 Essay

1. Understanding epidemiologic concepts of the chain of transmission of organisms from host to victim, describe how EH could have been infected.

This can also increase the risk of liver cancer. Approximately 90-95% of adults will recover within six months and not contact HBV again.(2) However, blood tests will always show that the person was infected with HBV and blood banks will not accept their blood. About 5-10% of adults and 25-90% of children under the age of 5 that are infected with HBV are not able to get rid of the virus after 6 months. These people are considered to be chronically infected, commonly called Hepatitis B carriers. The carrier rate of Hepatitis B varies throughout the world, being uncommon amongst westerners, but reaching as high as 20% in people from Asia and Africa. With the immigration of foreigners into new countries, Hepatitis B is now becoming established in parts of countries where it previously was not.

Section A (AO1): I will be focusing on communicable and non-communicable diseases are, how they are caused, types of them and the signs and symptoms of one of each and also how they are diagnosed.

3. What are example(s) of morbidity, mortality, and rate of incidence or rate of occurrence in the general population?

Asian-Americans are people who have origins in the Far East, Southeast Asia and the Indian subcontinent. In American census of 2000, Asians comprise of roughly 3.6% of the population or 10 million people. By 2050 the population will grow to 36.6 million people. Although Asian American women have the highest life expectancy, they “suffer disproportionately from certain types of cancers, tuberculosis and hepatitis B” (2). Liver cancer cases are relatively low in the United States but highest among Asian Americans and Pacific Islanders. Hepatitis B is a major cause of liver disease. Approximately 1 out of 12 Asian Americans has the chronic version of Hepatitis B. Many do not recognize it before it is too late (1).

The epidemilogic triangle describes the relationships and interactions among the infectious agent, the host, and

What is the connection between how a society defines health and how it pursues health?

Throughout this assignment I am going to be looking into the health and social topic of communicable and non-communicable diseases. I will be investigating into various aspects of two specific diseases. A high level of knowledge will be demonstrated with a detailed description of both communicable and non-communicable diseases as well as an understanding of epidemiology. I will then find a communicable and non-communicable disease example and describe the biological basis of each disease with an explanation to how the body responds to the disease. A list of at least three of the different signs and symptoms which are produced and displayed with the disease will then be shown. The changes shown as a result from the disease

Pathogenesis: The case study identifies a given disease. How does this disease process evolve? Describe the sequence of cellular and tissue events that take place from the time of initial contact with an etiological agent until the ultimate expression of a disease. (25 pts.) (Brittany, Jillian)

Epidemiology is the study of distribution and determinants of health-related states or events in specified populations and the application of this study to the control of health problems. The epidemiological triad model holds that infectious diseases result from the interaction of agent, host, and environment (CDC, 2012). Disease transmission occurs when the agent leaves the reservoir or host through a portal of exit, are the conveyed by some mode of transmission and enters through and appropriate portal of entry on infecting a susceptible host (CDC, 2012). This sequence is sometimes called the chain of

The epidemiology triangle has three sides. The sides consist of the host, the agent and the environment. The host is the person who is affected by the disease. The agent is the organism causing the disease. “In the case of type II diabetes, the agent could be the absence of a substance.” (McMurray, 2006). The agent interacts with the host and the environment to cause the disease. The environment is all the outside conditions that make the host susceptible to the agent. One condition of the environment could be the health of the host.

Hepatitis B is a viral infection which affects the liver and can cause fatty liver, liver cancer, or cirrhosis. There are two stages of the disease which are acute stage and chronic stage. Many people infected by the Hepatitis B Virus (HBV) will recover whiting the first six months, this is the acute stage. After six months without recovering, the patients develop the chronic stage of the infection, and will be more subjected to develop liver complications later in their life. According to World Health Organization (WHO), “More than 240 million people have chronic (long-term) liver infections. More than 780 000 people die every year due to the acute or chronic consequences of hepatitis B.” (July.2014). Why does one of the most worldwide and

Research is looking into genetic, hormonal and environmental risk factors in the cause of diseases. Possible exposure to certain things in the environment like the sun, infections, drugs, or, in some cases, pregnancy, may cause the immune system to

ten to thirty million people will become infected with the hepatitis B virus. I feel that because this disease is preventable, only knowledge can help reduce the number of people infected.
