Which viral hepatitis can often be asymptomatic but is known for transmission through blood?

The correct answer is Hep C, which is indeed often asymptomatic and primarily transmitted through blood. This virus is a major cause of chronic liver disease and is known for its potential to remain undetected for years, leading to significant health issues without manifestation of symptoms.

Transmission of Hep C predominantly occurs through sharing needles, blood transfusions (especially prior to blood screening), and less commonly, through sexual contact and from mother to child during childbirth. The asymptomatic nature of Hep C can delay diagnosis, resulting in serious liver complications like cirrhosis or hepatocellular carcinoma.

While Hep B is also a bloodborne virus and can be asymptomatic at times, it is more associated with transmission through sexual contact and other body fluids, along with blood. Hep A, on the other hand, is primarily spread through the fecal-oral route and typically presents with symptoms like fever, nausea, and jaundice, making it less relevant to the question's focus on asymptomatic cases and blood transmission.

Thus, Hep C stands out due to its specific profile of being frequently asymptomatic and predominantly bloodborne, emphasizing its significance in both acute and chronic liver disease management.
