Transcript of HCV

Hepatitis What is hepatitis ? Hepatitis is a general term for the inflammation of liver , Caused by Viral infection . Function of liver (1) produces bile for the break down of fats (2) Convert glucose into glycogen (3) filter the harmful substances from the blood (4)Storage of Vitamins & Minerals(Vitamin A,D,E &K) (5) Converts toxic product . (6) Metabolism of Carbohydrates, Fats, Proteins (7) liver excretes bile that digest the fats (8)It synthesizes plasma proteins. (9) Regulating the blood clotting . Types of Hepatitis : Hepatitis A Hepatitis C Hepatitis B Transmission : (1) Fecal-oral route
(2) Eating food or drinking water carrying virus
(3) Person to person Contact Symptoms : (1)Extreme tiredness
(2)Loss of appetite
(3)Muscle aches and pains
(4)Nausea and vomiting
(5)Dark urine
(6) Yellow Skin (Jaundice ) Prevention : Getting HAV Vaccine Treatment If a person is exposed to HAV and has not been vaccinated , Immune serum Globulin is available ...
In this case the liver heals on it's own . Transmission : (1)unsafe injection practices
(2)unsafe blood transfusions
(3)unprotected sexual contact.
(4)perinatal (from mother to baby at birth) Symptoms : (1)yellowing of the skin and eyes (jaundice)
(2)dark urine , extreme fatigue & nausea.
(3) vomiting &abdominal pain.
In some people, the hepatitis B virus can also cause a chronic liver infection that can later develop into liver cancer. Prevention: Getting the vaccine & Education of risks of using unsterilized Equipments . Treatment : Antiviral drug to stop the viral from multiplying and allow the liver to heal . It is impossible to really know the origins of hepatitis C
since there are no stored blood samples to test for the
virus that are older than 50 years. (1) Hepatitis A & hepatitis B discovered first .
(2) ''Hepatitis C '' Called : non-A ,non-B Hepatitis (NANBH )
(3) Could not Identify the virus for a decade
(4) In 1988 : Virus was finally Confirmed by Harvey
(5) In 1989 : Complete discovery of the virus & named by : Hepatitis C ` Key facts (1)Hepatitis C is a liver disease caused by the hepatitis C virus. (2) About 150 million people are chronically infected with hepatitis C virus (3) More than 350 000 people die every year from hepatitis C. (4) There is currently no vaccine for hepatitis C . (5) Every year, 3–4 million people are infected with hepatitis C Transmission Symptoms Prevention Treatment Life Cycle of hepatitis C Through :
(1) contaminated blood transfusions, blood products and organ transplants.
(2) injections given with contaminated syringes and needle-stick .
(3) being born to a hepatitis C-infected mother.
(4) sex with an infected person or sharing of personal items contaminated with infectious blood The incubation period for hepatitis C is 2 weeks to 6 months. (1) fever , fatigue & decreased appetite (2) nausea , vomiting & Abdominal pain . (3) dark urine & grey-coloured faeces (4) joint pain and yellowing of skin and the whites of the eyes. (1) unsafe injections. (2) unsafe blood products.
(3) unsafe sharps.
(5) unprotected sex with hepatitis C-infected people
(6) tattoos. Hepatitis C does not always require treatment. There are 6 genotypes of hepatitis C and they may respond differently to treatment. Combination antiviral therapy with interferon and ribavirin has been the mainstay of hepatitis C treatment. Unfortunately, interferon is not widely available globally some virus genotypes respond better to interferon than others, and many people who take interferon do not finish their treatment. This means that while hepatitis C is generally considered to be a curable disease, for many people this is not a reality. Geographical Distribution of hepatitis C Hepatitis C is found worldwide. Countries with high rates of chronic infection are Egypt (15% ) Pakistan (4.8%) and China (3.2%). The main mode of transmission is the unsafe injections Avoid the following : (2)lack of awareness (1)Infection control is not well developed in Egypt (3)Lack of standards and conscience Why 15 % ? WHO hepatitis day “It’s closer than you think” is the theme of this year’s World Hepatitis Day, which takes place on 28 July 2012.
The campaign focuses on raising awareness of the different forms of hepatitis: what they are and how they are transmitted; who is at risk; and the various methods of prevention and treatment. And here in our initiative we are hopefully asking you to give some of your attention, enthusiasm and the will to change our country and the world in to a better place for our families and the people who we care about.
we are to co-operate , achieve and reach our goals at the end.
Our hope is that you help us share the happiness of removing the burdens off the poor ,in need shoulders. Now you have to act prevention is better than cure Thank You ! Prepared by : Hager salah mahmoud
