Communicable diseases according to (Copstead & Banasik, 2010) is a condition or infection that is transmissible through coming into contact with an infected person. Contact with the infected person comprises of contact with an infected person bodily fluids (blood, saliva, or mucus), droplets, and/or air or food (Copstead & Banasik, 2010). Coming into contact in any of the above ways contributes to individual's illness. The pathogens transmitted through the body fluids and air encroaches upon the body compromising the normal functioning of body cells. This compromise may have differing impacts upon an individual's health ranging from a terminal illness to death.
Hepatitis BCommunicable Disease: Hepatitis B
Communicable diseases are diseases that can be transmitted via contact, droplet, air/food borne, blood, bodily fluids or congenital infection and cause individuals to become ill. The pathogens invade the body and damage normal cell functions, which could potentially cause death. Hepatitis B has infected over 200 billion people worldwide and killed over one million individuals per year (Centers for Disease Control and Prevention [CDC], 2013). The hepatitis B virus (HBV) can be prevented through education, spreading awareness and getting vaccinated which provides a lifetime of protection.
Over 200 billion people since the first case have been diagnosed with Hepatitis B in the world over. The number of individuals said to have suffered the demise following Hepatitis B infections stand at over one million per year (World Health Organization, 2013). Through awareness creation, education and vaccination spread of Hepatitis B is preventable. Vaccination is the ultimate measure of protection since it offers a lifetime protection from accusations of the virus causing the condition resulting to Hepatitis B (World Health Organization, 2013).
Description of Hepatitis B
Hepatitis B is a viral infection that is caused by the hepatitis B virus (HBV). It attacks the liver and can cause both acute and chronic disease. Acute HBV lasts less than six months and ones immune system is able to fight and clear the infection. Chronic HBV lasts longer than six months and the immune system is unable to fight the infection leading to liver failure, cancer or cirrhosis. Occasionally chronic HBV can go undetected for years due to a person being asymptomatic (Mayo Clinic, 2011).
Mode of Hepatitis B is a virus-caused the infection that attacks an individual's Liver and causing illness ranging from acute to chronic levels. The virus causing Hepatitis B is the hepatitis B virus (HBV) and once in the body system on individual it can go undetected for a lengthy period of years. The two types of illnesses (acute and chronic) differ considering the length of time a normal body immune system takes to fight and clear the infection. In the case of Acute HBV, the body's immune system is capable of fighting and clearing the infection in less than six months. For the case of Chronic HBV, the body immune system is unable to fight the condition in less than six months. The resulting situation from the body system failure to fight the infection is cancer, liver failure or cirrhosis. In occasional cases, HBV will likely go undetected for a number of years following an individual being an asymptomatic person (Mayo Clinic, 2011)
In highly infected areas of the world, HBV is most commonly spread from mother to her baby at birth or from person to person in early childhood (World Health Organization [WHO], 2013). The HBV is also spread via parenteral contact with infected blood or blood products, sharing of or accidental needle sticks and having unprotected sex with someone who's blood, saliva, semen or vaginal secretions are infected and enter your body (Copstead and Banasik, 2010).
Signs and Symptoms
Signs and symptoms of HBV may never appear or appear over a two to six-month period. Signs and symptoms include abdominal pain, dark urine, fever, joint pain, loss of appetite, nausea and vomiting, weakness, fatigue and jaundice (yellowing of the skin and/or sclera) (Mayo Clinic, 2011).
The most prevalent mode of transmission of HBV is from the mother to child at childbirth or from one person to the other in early (World Health Organization, 2013). Exposure to infected blood following parenteral procedure, bodily fluid exchange, sharing syringe and accidental needle sticks serve as…[continue]

Some of these illnesses have unique features which make them particularly difficult to track as subjects of surveillance. For example, Lyme tests are often unreliable. Also, "many viruses and bacteria cause nonspecific syndromes or symptom complexes that include most diarrheal and respiratory symptoms" (Ritz, Tager, & Balms 2005). This is also true of tracking the efficacy of treatments: "in cases where there are long delays between the implementation of
Epidemiological Aspects of Hepatitis B in Community-Based Health Educating About Hepatitis B Overview of Hepatitis B Epidemiology Hepatitis B is caused by infection with the Hepatitis B virus (HBV) ("CDC," 2012). The highest concentrations of HBV are found in blood, while other body fluid, such as semen, vaginal secretions, and wound exudates, show lower concentrations ("CDC," 2012). HBV infection can be either chronic or self-limited ("CDC," 2012). The incubation period can range from
This is particularly the case in sub-Saharan Africa where clinicians have often come to rely on signs and symptoms alone to make diagnoses." (Nicoll, Walraven, Kigadye, Klokke, 1995) The laboratory environment is critical to administering testing to determine population rates of HIV / AIDS throughout nations and perhaps continents where the lacking of resources facilitates a substandard environment for care. In the case of the African nation of Mozambique, which
" More unfavorable publicity came in June when Jintao had to undergo medical checkups to ensure he was SARS-free when meeting President Bush and other G-8 leaders in France. There is little doubt that China's international standing was clearly badly damaged by its government's mishandling of the SARS epidemic. On July 21, 2004, Dr. Bates Gill, Freeman Chair in China Studies Committee on House International Relations Subcommittee on Asia and the Pacific,
Immunization of children in the United States [...] full detail why the immunization rate of children in the U.S. is high, and the validity of the reasons why some parents choose not to immunize their children. It will also explain if those children will be protected by "herd immunity." Most children in the United States receive immunization from a variety of diseases when they are toddlers. Yet, some parents
Combined with the human development index these studies showed that using parameters that affect the standards like education, longevity, and standard of living it is possible to predict the environmental health factors, and find the actual health indicators. (Corvalan; Briggs; Zielhuis, 2000, p. 159) The first problem is the distinguishing between health promotion and health education. Work place health actions tend to be concerned about disease prevention. So far it
When they enter the gallbladder and lymphatic tissue they multiply in enormous numbers. It is when they re-enter the intestinal tract that the disease can be diagnosed from stool samples. Symptoms The first symptoms are usually headache, muscle pain and a fairly high fever. The problem is that these symptoms only occur about ten days after infection. It isn't until four to five days later that a rash occurs. The rash
