**Question:** Which of the following statements about Hepatitis 'C' is true -

A. Hepatitis C is caused by exposure to blood or blood products
B. The incubation period is shorter than that of Hepatitis A
C. Hepatitis C is a sexually transmitted infection
D. Antibodies to Hepatitis C virus (HCV) can be detected immediately after infection

**Core Concept:** Hepatitis C is a viral infection caused by the Hepatitis C virus (HCV), primarily transmitted through exposure to blood or blood products. The incubation period varies, ranging from 14 to 100 days, making it similar to Hepatitis A. Hepatitis C is not sexually transmitted, although co-infection with HIV increases the risk of progression to chronic hepatitis C. Antibodies to HCV can take weeks to develop after infection, not being detected immediately after infection.

**Why the Correct Answer is Right:** Hepatitis C is primarily transmitted through infected blood and blood products, not through sexual contact like Hepatitis B. The incubation period of Hepatitis C is longer than that of Hepatitis A, ranging from 14 to 100 days, making it similar to Hepatitis A. Antibodies to HCV are not detected immediately after infection, as it takes weeks for the immune system to respond to the virus.

**Why Each Wrong Option is Incorrect:**

- Option A: Hepatitis C is primarily transmitted through blood and blood products, not sexually transmitted.

- Option B: The incubation period of Hepatitis C is longer, not shorter, ranging from 14 to 100 days.

- Option C: Hepatitis C is not sexually transmitted, although co-infection with HIV increases the risk of progression to chronic hepatitis C.

- Option D: Antibodies to HCV are not detected immediately after infection, taking weeks to develop, not immediately.

**Clinical Pearl:** Hepatitis C is a significant global health concern, affecting millions of people worldwide. Early diagnosis and appropriate treatment can prevent progression to chronic hepatitis C and its associated complications, such as cirrhosis and liver cancer. It is crucial for healthcare professionals to educate patients and the general public about the modes of transmission, such as using unsterile medical equipment, blood transfusions, and intravenous drug use.
