Q64 (IAS/2010) Science & Technology › Biotechnology & Health › Human infectious diseases Answer Verified

Consider the following statements: 1. Hepatitis B is several times more infectious than HIV/AIDS 2. Hepatitis B can cause liver cancer Which of the statement given above is/are correct?

Result
Your answer: —  Â·  Correct: C

Explanation

Both statements are correct. Hepatitis B virus (HBV) is substantially more infectious than HIV: public health sources note HBV can be roughly 50–100 times more transmissible per exposure than HIV, reflecting its higher infectivity via blood and body fluids [1]. In addition, chronic HBV infection is a well-established cause of progressive liver disease and is linked to cirrhosis and hepatocellular carcinoma (liver cancer); international guidance groups classify HBV among the hepatitis viruses that can cause chronic infection and hepatocellular carcinoma [2]. Therefore statements 1 and 2 are both true.
