Transcript of Hepatitis C

History of Hepatitis C
The natural history of Hepatitis C virus infection remains incompletely understood. Theres so much controversy that surrounds the issue of the natural history of Hepatitis C. Many authorities see this disease as a fasting progression and likely to be responsible for causing death.
Effects on Pregnant
women & infants
Pregant women- cannot have standard medicine to treat Hepatitis C it isn't safe for the unborn baby. Women with Hepatitis C during pregnancy are most likely to develope Gestational Diabetes (to much sugar in the blood during pregnancy).
Infants- Babies born to moms with Hepatitis C may be more likely to be born prematurely or have low birth weight. Medicines taken during pregnancy can cause the baby to be born with serious defects or even death at birth. Though the chance of passing Hepatitis C to an infant is uncommon the chances are 1 in 20, but if the mother has high levels of Hepatitis C there is a higher chance of the infant having it.

How do you know if you have Hepatitis C?
Minor Hepatitis C recovers by itself it has little to no symptoms, so it can go undiagnosed. Chronic Hepatitis C does display symptoms although, the symptoms can take up to 30yrs after obtaining the virus for them to show.
Short Term
: the phase lasts for the first six months, as said before most people have no symptoms. If symptoms do occcur they develope in about 7-8 weeks after being exposed to the virus.
Some people become jaundced (go 'yellow'). This is due to build up of a chemical called Bilirubin. Which is made in the liver and spills into the blood making a person appear ¨yellowish¨. It is unusual to get severe symptom
Long term
: The infection is chronic when it lasts longer than six months. Long term effects varies considerably between people, its very unpredictable. Though those who have developed chronic infection:
Some have mild to no symptom, though can still pass infection to others who could develope problems
Some develope sypmtoms due to presistent inflammation of the liver.
Most common effects are: extreme tiredness, poor concentration, memory problems, muscle and joint aches, jaundice, and depression.
There is no relationship between symptoms and the liver, people can have liver inflammtion without having any symptoms.
Some people develope 'Cirrhosis' its scarring of the liver, which can cause serious problems like liver failure when it is severe.
Some people never develope an effect until the liver starts to fail
If Cirrhosis is severe it can develope into liver cancer.

Effects on Elderly
Treatment for elderly should be carefully considered on individual bases because regular treatment can be toxic in elderly.
There is a significant risk of developing liver disease.
Should be followed long term in order to assess the influence of the therapy of the liver and survival.
Also some treatments are less effective on the elderly.
Although scientist are trying to replace the standard treatment for elderly into a less toxic, orally administrated drugs for Hepatitis C.
Short/Long Term Effects
Hepatitis C
How long has Hepatitis C been around?
Scientists know that hepatitis C has been around since at least the 1940's. They discovered the virus in some old frozen blood taken. Until 1989 the hepatitis C virus was known as non-A non-B hepatitis because the virus had characteristics that were different than the two known strains of hepatitis at the time, which were hepatitis A and B.
Discoverers/ researchers
In 1989,Michael Houghton, PhD and his Chiron colleagues were the first to identify the hepatitis C virus (HCV) in association with the CDC. Their discovery led to a series of HCV tests that are now used globally to screen the blood supply to prevent infection. Their work also led to the identification of important new anti-HCV drug targets. In addition to HCV, Dr. Houghton's group was the first to characterize the hepatitis D virus (delta virus)
What is Hepatitis C?
It's an infectious disease caused by the hepatitis C virus (HCV) that attacks the liver and leads to inflammation
HVC is spread by blood-to-blood contact asscociated intravenous drug use
Hepatitis C is considered to be the most serious out of several hepatitis viruses
HCV can cause both chronic (long term) and acute (short term) infections of the liver
Symptoms Include:
Fever
Fatigue
Loss of appetite or anorexia
Nausea
Vomiting
Abdonminal pain
Dark colored urine
Joint pain
Tenderness in liver area

Cures
Currently, theres no cure for hepatitis C. Sometimes a person's body will fight off the hepatitis C infection; serving as a natural cure for the disease. However, the majority of people with hepatitis C have a long-term liver infection. Medications can be used to help the body destroy the hepatitis C virus, but they do not always cure the disease entirely. Even if treatment does not offer a cure, it may help stop the swelling, scarring, and other damage to the liver that the disease may cause.
Treatments
Most common medicine used includes pegintron and antiviral drugs. Theses medicines helps the body get rid of the virus and reduce the risk of cirrhosis and liver cancer which can result to long term HCV infection. You need to take your medicine as instructed by your health provider. A liver transplant may be recommended for a person who develops cirrhosis and liver cancer
Prevention Efforts
Don't share personal care items that might have blood on them, ex: razors or toothbrushes.
Avoid injecting drugs, for drug users enter a treatment programs.
Never share needles or syringes.
Get vaccinated against hepatitis A & B.
Consider the risk of getting tattoos or body piercings a wrongly disinfected tool can infect you.
Do not donate blood, organs, and tissue if you have Hepatitis C.

Questions
3.) How is Hepatitis C spread?
A: Kissing
B: Sharing drinks
C: blood-to-blood contact(ex: sexual intercourse)
5.) Is there a cure/treatments for Hepatitis C?
A: There is a cure for hepatitis C so therefore we dont need treatments
B:There is no cure but you can use antibiotics to treat it
C:There is no cure but you can use antiviral drugs to reduce the risk of cirrhosis and help the body get rid of the virus

4.) HCV can cause which term of infections of the liver?
A: Acute term
B: Chronic term
C: Both

Incidence
Although only 849 cases of confirmed acute Hepatitis C were reported in the US in 2007, CDC estimates that around 17,000 new HCV infections occurred that year, after adjusting for asymptomatic infection and underreporting.
Persons newly infected with HCV are usually asymptomatic, so acute Hepatitis C is rarely identified or reported
