What is Hepatitis ?

Hepatitis C is caused by the Hepatitis C virus (HCV). It is a bloodborne virus primarily transmitted through direct contact with infectious blood. This can occur through sharing needles, transfusions of contaminated blood, or through childbirth from an infected mother.

The infection can present in two forms: acute and chronic. Acute hepatitis C usually develops within six months of exposure. In many cases, it resolves on its own. Conversely, chronic hepatitis C is defined by the persistence of the virus beyond six months and can lead to severe liver diseases, such as cirrhosis or liver cancer.

Virology of Hepatitis Virus

The Hepatitis C virus is classified as a member of the Flaviviridae family. It has a single-stranded RNA genome. One of the notable features of HCV is its high mutation rate. This variability allows the virus to evade the immune response and develop resistance to therapies.

HCV has several genotypes. The genotype refers to the genetic variation of the virus and influences treatment response. For example, Genotype 1 is the most prevalent in many parts of the world, and it is known for being somewhat more difficult to treat compared to other genotypes. Understanding the viral structure and its characteristics is essential for tailoring treatment plans and improving patient outcomes.

Epidemiology and Transmission

Epidemiology plays a critical role in understanding the spread of Hepatitis C. Globally, it is estimated that about 71 million people are living with chronic Hepatitis C. The highest incidence rates are found in regions with limited healthcare resources, where blood screening may not be stringent.

Transmission occurs mainly through activities that involve blood exposure. Notable risk factors include:

Sharing needles among people who inject drugs.
Receiving unscreened blood products, especially in low-income countries.
Certain medical procedures in unregulated settings.
Vertical transmission from mother to child during childbirth.
