What is Hepatitis B?

Hepatitis B is indeed a disease of the liver that results from infection with the Hepatitis B virus (HBV). This virus is particularly noteworthy because it can remain viable and infectious for an extended period, even outside the body, such as in dried blood, for up to a week. This characteristic contributes to its transmission risk, as contaminated surfaces can pose a health threat. The disease can lead to chronic liver conditions, including cirrhosis and liver cancer, making it a significant public health concern. Understanding its mode of transmission and the role of blood in spreading the infection is crucial for prevention and control measures. Other options incorrectly attribute Hepatitis B to different organs or types of diseases, such as kidney issues or respiratory infections, which do not pertain to this specific viral infection.
