Hepatitis A is a virus or an infection that causes liver disease and inflammation of the liver. According to Centers for Disease and Prevention, hep A is a self- limited disease that does not cause a chronic infection and it is rarely fatal. The virus is an infectious disease of the liver which cannot be transmitted by sneezing and coughing. It is usually transmitted from person to person through the feces or the mouth, from consuming contaminated food or water. Many people do not experience any symptoms of hepatitis A, but if someone was to get it, then the symptoms could last from 2 weeks to 6 weeks. The blood is tested to determine how the liver is functioning. The blood is usually taken from the vein in the arm and is taken to the lab …show more content…
WHO estimates that there are 1.4 million new infections per year spread throughout the world. The best way to prevent hep A infection is to get vaccinated. Causes Hepatitis A is caused by a virus that infected the liver cells which spread when people eat and drink something contaminated with feces. According to Mayo Clinic, the virus can spread by eating food when someone with the virus does not thoroughly wash their hands after using the restroom, drinking water that has been infected with feces, eating raw shellfish from water polluted with sewage, being in close contact with someone who is infected even if the person has no symptoms, and having sexual partners who have the virus. According to the Centers for Disease Control, a hep A vaccine is recommended for homosexual men, laboratory workers, people who use illegal drugs, people with chronic liver disease, and people who travel the world. Cases of hepatitis A are not distinct from other types of acute viral hepatitis. According to WHO, specific diagnosis are made by the detection of Hepatitis A Virus (HAV)-specific Immunoglobulin G (IgM) antibodies in the blood. Additional tests include reverse …show more content…
The signs are fatigue, sudden nausea, vomiting, loss of appetite, intense itching, dark urine, clay colored bowel movements, abdominal pain in the right side, joint pain, and a fever up to 102 degrees Fahrenheit. Although the symptoms may be moderate, the outcome of the infection can be a severe illness that lasts for several months. The vaccine of immunoglobulin can protect you from infection if the person receives it within two weeks of being introduced to hep A. If the infected person has a long-term liver disease, then the symptoms also may cause the virus and it also can occur for people over the age of 50. Hepatitis symptoms are so minor, people usually do not realize they are infected with the
The Hepatitis B virus is a disease that affects the liver and results in swelling and loss of normal function in the liver. It is estimated that 350 million people are infected with Hepatitis B worldwide, with 50 million new cases diagnosed every year.(1) In the Unit...
...y infections that could cause short term or long term unneeded damage. For this reason doctors and health care professionals are recommending that all people of all ages to get theses vaccines (University of Maryland Center, 2014). Other ways to prevent this disease are to simply keep clean and be aware of good hand hygiene (University of Maryland Center, 2014). By washing your hands with antimicrobial soap and warm water with friction, most bacteria are killed. Doing this prevents organisms from potentially getting inside your body.
Most people who are exposed to the fungus experience symptoms, but do not get sick. The signs—fever, cough, and exhaustion—are difficult to distinguish from the flu, and can last for weeks to months. In people with weakened immune systems, the infection can cause more severe conditions such as meningitis or death. There is no vaccine for valley fever, and many in the general public (including the medical community) know very little about the illness. This lack of knowledge has allowed many milder cases to go undiagnosed, leading to underreporting.
The Hepatitis A Virus affects many different systems within the body. The first being the digestive system and the gastrointestinal system because Hepatitis A causes an acute liver infection. The liver’s job is to process nutrients, filter the blood and toxin from your body, and fight infections. It produces important blood components, proteins, and bile which helps you digest food. The liver also stores glucose and vitamins. The Hepatitis A Virus causes inflammation that interrupts the liver’s ability to perform these vital functions. Having a healthy liver is crucial to your health because it supports many other body systems. For example, one function of the liver is to produce bile which is needed to break down fats. The body stores bile in the gallbladder and then sends it to the beginning section of the small intestine. Bile is then combined with other digestive
There are four phases of Hepatitis B: infection, inflammation, fibrosis, and cirrhosis. In the first phase, HBV invades the liver and goes for the nucleus, where it releases contents of DNA and polymerase into the surroundings. It then maneuvers its way to the cell’s components and enzymes. The polymerase sways the liver cells to make segments of the HBV DNA from RNA. The virus makes liver cells create spare parts for other HBV viruses. Replicas are released from liver cell into the bloodstream, destroying host cell and infecting other healthy liver cells. This entire process can take a few hours to occur, but must continue multiple times for serious damage to occur. The second phase is inflammation. Inflammation is caused by lymphocytes trying to get rid of the virus, but they also release harmful chemicals that damage the cells and take part in damaging the liver. The third phase is fibrosis. Fibrosis is scar tissue caused by inflammation and chronic infection. According to Everson and Weinburg, (2002, pg. 64) “Only 5/10% of people develop chronic Hepatitis B from acute Hepa...
Pathogens are a type of microorganism that spreads viral and bacterial diseases. These diseases when present in human blood and body fluids are known as blood borne pathogens, and can spread from one person to another. (Worcester polytechnic institute) The most serious types of blood borne diseases are the hepatitis B virus (HBV) and hepatitis C virus (HCV), which can cause liver damage; and HIV (human immunodeficiency virus), which is responsible for causing AIDS (acquired immune deficiency syndrome). The blood borne pathogens can be spread when the blood or body fluids (semen, vaginal fluid, breast milk, and amniotic fluid) of an infected individual comes into contact with mucous membranes or an open sore or cut on the skin of another person. Mucus membranes are located in the eyes, nose, mouth, and other areas as well. ("Bloodborne pathogens: MedlinePlus Medical Encyclopedia") Two of the most common ways that pathogens are transmitted is through the exchange of fluids during sexual intercourse or by sharing infected IV needles.

Cirrhosis is a deterioration of the liver resulting from heavy scarring, causing the liver to not be able to function properly. If cirrhosis becomes severe, a liver transplant may be the only solution (“Beyond Hangovers: Understanding Alcohol's Impact on Your Health” 14). It is difficult to calculate when a person will develop cirrhosis, because an alcoholic could never develop the disease, but someone who drinks socially could. It is also unknown why cirrhosis is more prevalent in women (Freeman).... ...
People affected with Legionnaires disease often have signs and symptoms extremely similar to signs associated with the flu, such as muscle aches, headaches, loss of appetite, and cough. Fevers tend to get high, ranging from temperatures of 102-105 degrees. Symptoms of Legionnaires disease usually do not show up until 2-10 days after a person is infected with the bacteria, and people normally experience other symptoms such as diarrhea and stomach cramps. Pontiac Fever, also known to be associate...
Hepatitis A is a usually short acting virus that occurs in humans and monkeys. It is caused by the Hepatovirus and the species is Hepatitis A Virus. There are two major ways in which Hepatitis A can be transmitted. One way is from person to person. This transmission occurs when the fecal matter of an infected person gets ingested by another person. Other ways Hepatitis A can be transmitted from person to person are through direct contact with an infected person, such as sexual contact, and sharing of needles for intravenous drug use. Hepatitis A can also be transmitted through coming in contact with contaminated food or water. Also foods that are uncooked or undercooked and have been contaminated with Hepatitis A can transmit the virus. (Bennett,
What is hepatic cirrhosis? According to the medical dictionary hepatic cirrhosis is when scar tissue replaces the liver’s healthy tissue. This disease changes the structure of the liver and blood vessels that nurture it. It reduces the liver’s capability to produce proteins and process hormones, nutrients, medications, and poisons. Cirrhosis is an illness that gets worse over time and possibly can become life threatening. This serious illness is ranked as the ninth leading cause of death in the U.S. It is the third most common cause of death for adults between 45 and 65 years of age. It occurs in more than fifty percent of undernourished chronic alcoholics. Unfortunately it kills about 35,000 people per year. In other country’s such as Africa and Asia death from cirrhosis is usually caused by hepatitis B.
There is a disease spreading out in the world called Hepatitis C. It affects the liver and may cause the liver to fail. This disease is caused by a virus called Hepatitis C virus which is also known as HCV. About 32,000 people are affected with this disease per year only in the United States area. Some It’s a disease with many symptoms and many causes. of these symptoms are easy bruising, upset stomach and fever. These are just some of the many symptoms that come from the virus. Hepatitis Cs nature of the causative agent is determined by many things. The biological data of this disease is filled so much information. It is estimated that over 180 million people have gotten Hepatitis C and it is growing.
Hepatitis B, an infectious disease caused by the Hepatitis B virus (HBV, a DNA virus), was formerly called serum hepatitis, inoculation hepatitis and post-transfusion hepatitis. Infection with HBV may result in acute, fulminant or chronic hepatitis, sometimes even resulting in a chronic asymptomatic carrier state, apart from hepatocellular carcinoma and liver cirrhosis (Davis 179). The disease is transmitted when an individual comes in contact with infected blood or objects. It may also be transferred from an infected mother to her infant either during or after birth (Zuckerman et al. 211). Transmission may also occur by accidental inoculation from infected needles and hospital equipment, intravenous drug abuse, body piercing, tattooing, and mouth-mouth kissing (Zuckerman et al. 210). The risk of Hepatitis B is particularly high in individuals with multiple sex partners, and in homosexuals. The HBV virus occurs in morphologically different forms in the serum of infected individuals. HBV infection has an incubation period of about 75 days. Systemic symptoms of the disease include fatigue, fever, dyspepsia, arthralgia, malaise, and rash, while local symptoms include hepatomegaly, jaundice, dark urine, and pale stools (Davis 179; Zuckerman et al. 210).
This case study is about Abdul Chidiac, a 51 year old male, married with 4 children. He had a medical history of hypertension, hypercholesterolaemia and cirrhosis with two admissions in the last six months. He is a smoker and drinks beer, 5-6 bottles per day. As Carithers & McClain (2010) explained the patient’s medical history is another indicator of the risk for cirrhosis; the progression to cirrhosis is adaptable and may take time over weeks or many years. Cirrhosis is a liver disease characterized by permanent scarring of the liver that interferes with its normal functions including alcoholism. Most people who drink large amounts of alcohol cause harm to the liver in some way (Heidelbaugh & Bruderly, 2006). The cause of cirrhosis is not yet known, but the connection between cirrhosis and excessive alcohol ingestion is established (Jenkins & Johnson, 2010). Common causes of cirrhosis include: alcohol abuse, hepatitis B infection, hepatitis C infection and non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (Schuppan & Afdhal, 2008).
Viruses can be transmitted in many ways. Being in contact with an infected person will most likely transfer the virus. One can also obtain the virus through swallowing, inhaling, and unsafe sex. Poor hygiene and eating habits usually increase the risk of catching a viral infection. Contracting a viral infection is followed by adverse s...
