The essential points about hepatitis that will help in the prevention and understanding of the infection are as follows:What is Hepatitis?In simple terms, hepatitis means chronic or acute inflammation of the liver. The prevalent cause of hepatitis is a viral infection, but chronic alcoholism, some drugs like acetaminophen, and autoimmune disorders can also cause hepatitis. Prevalence of HepatitisAccording to the statistics given by World Health Organization, 325 million people around the globe have chronic hepatitis A or C infections. It is a pretty severe number!Is Hepatitis Fatal?Hepatitis can be fatal, especially the chronic forms. When the liver is inflamed for an extended period, the chances of hepatic cancer increase because inflammation provides a fertile ground for malignancy to develop. According to WHO, one million people die due to hepatic cancer, the leading cause of chronic hepatitis.Types of HepatitisFive hepatitis viruses cause liver inflammation. Hepatitis A Hepatitis B Hepatitis C Hepatitis D Hepatitis EHepatitis A, B, and C are the most common causes of hepatitis worldwide. Viral TransmissionThe hepatitis viruses are transmitted in several ways. Contact with the fluids of an infected person Blood transfusion from an infected person Use of contaminated syringes Sharing items like razors and toothbrushes with an infected person Vertical transmission (mother to child during birth) Sexual intercourse with an infected individualScreeningIt is essential to check the blood of donors, significantly above 40, for the presence of the virus. There are various techniques available for screening.

Dark urine Light colored stool Decreased appetite Weight loss VomitingHow is The Diagnosis Formed?Hepatitis can be diagnosed by blood tests, imaging tests, and liver biopsy. The antigens of hepatitis viruses and the antibodies formed against the antigens can also be used for diagnosis. For example, to diagnose hepatitis C the presence of anti-HCV antibodies is checked through the Enzyme-linked Immunosorbent Assay (ELISA). Tests which determine a past infection or latent infection are also available. Hepatitis-panel includes the following tests: Hepatitis A antibody, IgM HepB antibodies; IgM, core antibodies, surface antigen hepC antibodiesPreventing HepatitisVaccines are available for hepatitis A and B viruses. The vaccination against hepatitis B automatically protects against hepatitis D because only the individuals infected with the hepatitis B virus can get infected with hepatitis D.
