Hepatitis is caused by a virus that is targeted at the liver, one of your most important organs!! Specifically, it causes inflammation and injury to the liver. Hepatitis comes in many different forms, five to be exact. There is Hepatitis A, B, C, D & E. Hepatitis is caused mainly by viruses, all of which are set on shutting down your liver. I will be specifically concentrating on Hepatitis A in this report. Hepatitis A is also known as infectious Hepatitis, an extremely contagious viral infection that often effects young children and young adults, especially those in large groups. It has been known to break out in schools, summer camps and music festivals etc.
Hepatitis A is also very common in developing nations. Outbreaks occur due to unsanitary conditions such as contamination of the food and water supply.
The Liver: The liver is an organ which is located upper right part of your abdomen. It has one main function. This function is to clean out your blood. How this happens is from your inferior venacava, there is a group if veins called the mesenteric veins. They branch off and take dirty blood to your liver to be cleaned. Now, when the virus moves in and stops the liver from doing its job, just imagine all the toxins and unwanted waste and chemicals that build up in your body.!!
Causes: Hepatitis A is transmitted almost always by the fecal oral route. It is spread by close personal contact with fecally contaminated water supplies, fruits and vegetables. Poor personal hygiene promotes spread of the virus as well which is why the incidence of Hepatitis is higher in developing nations, where poor sanitary conditions exist. It can also be transmitted by raw or partially cooked clams from contaminated water.
Properties of the virus: The hepatitis A virus is a non - enveloped 27 nano meters in size, virus. It is characterized as a RNA based virus. Inactivation of viral activity can be achieved by heating to 100 °C for five minutes, and by contact with formaldehyde and chlorine or by ultraviolet irradiation. The virus is present in the liver, bile, stool and blood during the illness.
Symptoms: The symptoms of viral hepatitis are not very pretty. Getting Hepatitis is not a fun experience. The first symptoms of Hepatitis A are mild and vague. They generally appear from about 2 weeks to 6 months after exposure to the virus. The symptoms at first seem as though you have a mild case of the flu. Therefore, you feel abnormally tired. This keeps up for a few days and you begin to feel a loss of appetite as well as nausea. A low grade fever between 100 °f - 102 °f is present. A pain and discomfort in the abdomen above the liver is also common, due to enlargement of the liver. After a few days of torture, a person’s urine becomes darker than usual and then jaundice, (a yellowish discoloration of the skin) appears. Jaundice and the dark urine indicate that liver is not functioning properly in removing a reddish-yellow pigment called bilirubin from the blood.
Treatment / Prevention:
There is no specific treatment for viral Hepatitis. Bed rest and preferably hospitalization is a necessary step in the early treatment. Even though Hepatitis A is a highly contagious virus, isolation of the patient to a single room is not necessary. However, proper prevention methods such as washing your hand after handling the patient, careful handling of the body fluids and feces and wearing gloves when drawing blood is important.
Prolonged bed rest is not essential for full recovery but patients feel better with restricted physical activity. A high calorie diet is a good idea and because many patients have nausea late in the day, the major caloric intake is best given in the morning. Intravenous feeding is necessary if the patient has continuos vomiting. Isolation of the patient to a single room and bath room is unnecessary, however the patient and other people in contact should be reminded of preventative measures such as washing hands and of careful handling of body fluids and feces. Gloves should be worn when handling or drawing blood. Patients may be discharged from the hospital when the symptoms improve. For patients with severe

Animal RightsAnimal Rights At the University of Oregon, Barbara Gorden-Lickey, Ph. D., sewed kittens\' eyes shut and forced them to jump from a height onto a platform surrounded by water so she could study the effects of sight deprivation on the brain. Cruel and inhumane experiments like this one is an excellent reason why people should recognize the importance of animal right activist groups such as PETA (People of the Ethical Treatment of Animals). Founded in 1980 by Ingrid E. Newkirk and Alex Pacheco, PET
AIDSAIDS AIDS (acquired immunodeficiency syndrome) is a disease caused by a virus- HIV (human immunodiciency virus). The first cases in this country came to light in the early eighties. Although the origins of AIDS remains uncertain it is thought to have emerged decades ago in sub-Saharan Africa. There is a closely related virus (simian immunodeficiency virus, or SIV) that is found among monkeys in that particular area which AIDS is thought to have evolved from (Combating AIDS 353). When the virus f

People with KS are distinguished by their placement in four categories. The first category consists of elderly males of Mediterranean or Eastern European Jewish descent. The second category consists of individuals of all ages from Africa. Neither one of these categories is associated with immune deficiency or known envir

Bacteria are everywhere: in water and soil and in the bodies of humans and other animals. The majority of bacteria don’t have the ability to cause disease, but that doesn’t mean that they are totally harmless. The problem arises when disease – causing bacteria interact, and are frequently in contact with the commensal, or h

Our Radiant Planet- Depletion of the Ozone LayerOur Radiant Planet- Depletion of the Ozone Layer Ozone is a relatively unstable form of molecular oxygen containing three oxygen atoms produced when upper-atmosphere oxygen molecules are split by ultra violet light. Stratospheric ozone is found in a broad band, extending generally from 15 to 35km above the earth. Although the ozone layer is surprisingly thin, it acts as a protective shield to the earth, as it filters out most of the harmful solar ultraviolet radiation (in particular UV-B) that w
Global Warming: The TruthGlobal Warming: The Truth 1 English 101 3rd Draft of MP# 4 According to the National Academy of Sciences, with accelerated global warming during the past two decades, there is now new and stronger evidence that most of the warming over the last 50 years is due to human activities (U.S. EPA 1). These activities have altered the chemical composition of the atmosphere through the buildup of greenhouse gases. Greenhouse gasses occur naturally with in our atmosphere.

IllnessesIllnesses illnesses caused by microorganisms and transmitted from an infected person or animal to another person or animal. Some diseases are passed on by direct or indirect contact with infected persons or with their excretions. Most diseases are spread through contact or close proximity because the causative bacteria or viruses are airborne; i.e., they can be expelled from the nose and mouth of the infected person and inhaled by anyone in the vicinity. Such diseases include diphtheria, scarlet

AidsAids Acquired Immune Deficiency Syndrome (AIDS), suppresses the immune system related to infection with the human immunodeficiency virus (HIV). A person infected with HIV gradually loses immune function along with certain immune cells called CD4 T-lymphocytes or CD4 T-cells, causing the infected person to become vulnerable to pneumonia, fungus infections, and other common ailments. With the loss of immune function, a clinical syndrome (a group of various illnesses that together characterize a di
Pop and its ProblemPop and its Problem Did you know the adult person drinks about 2-3 cans of pop a day. Teenagers drink about 3-4 cans a day. But drinking too much can be a real problem because the dangers seem hidden. Pop may seem like a good combination with pizza or other salty or fatty foods because the salt in the food makes your tongue crave sweetness. The sweetness of the pop compensates the urge and it makes you able to eat more fatty food if you drink pop. The sugar in the pop is also extremely bad for y
