Correct Option (b):
Hepatitis B has an effective vaccine. This vaccine was a pioneering product of recombinant DNA technology and is widely used globally for prevention. Therefore, the statement "Hepatitis B, unlike Hepatitis C, does not have a vaccine" is incorrect.
Incorrect Options:
Option (a): Hepatitis B virus (HBV) transmission routes are similar to those of Human Immunodeficiency Virus (HIV). These include contact with infected blood, unprotected sexual intercourse, and perinatal transmission from an infected mother to her child. Thus, the statement is correct.
Option (c): Worldwide, the prevalence of Hepatitis B and C infections collectively surpasses that of HIV infection by a significant margin. Global health statistics, including those from the WHO, corroborate this fact. Thus, the statement is correct.
Option (d): A substantial number of individuals infected with Hepatitis B or C viruses may remain asymptomatic for extended periods, often years. This latency complicates early diagnosis and can lead to the progression of chronic liver disease without noticeable symptoms. Thus, the statement is correct.
