What is a key characteristic of Hepatitis B?

The key characteristic of Hepatitis B is that it is a viral infection that affects the liver. This virus specifically targets liver cells, leading to inflammation and potentially causing serious complications, such as cirrhosis or liver cancer. Understanding that Hepatitis B is a viral infection is crucial for recognizing its mode of transmission, symptoms, and implications for liver health.

This virus is transmitted through contact with infectious body fluids, which can include blood, semen, and other bodily fluids, rather than being limited to saliva. Additionally, Hepatitis B is not caused by environmental toxins; it is infectious in nature. Furthermore, there are effective vaccines available that can prevent Hepatitis B infection, making the statement about the lack of vaccinations incorrect. Understanding these fundamental aspects is essential for effectively managing and preventing the disease.
