Questions: Which statement is true of Hepatitis C? Hepatitis C is less likely to lead to serious complications than hepatitis A. Hepatitis C usually requires no treatment other than bed rest and increasing fluid intake. Hepatitis C is an emerging communicable disease of epidemic proportions. Hepatitis C has decreased dramatically since the development of a vaccine in the 1990s.

The answer is the third one: Hepatitis C is an emerging communicable disease of epidemic proportions.

Explanation for each option:

1. Hepatitis C is less likely to lead to serious complications than hepatitis A.
   This statement is incorrect. Hepatitis C is more likely to lead to chronic infection, which can result in serious complications such as liver cirrhosis and liver cancer. Hepatitis A, on the other hand, usually resolves on its own without leading to chronic liver disease.

2. Hepatitis C usually requires no treatment other than bed rest and increasing fluid intake.
   This statement is incorrect. Hepatitis C often requires antiviral medications to prevent chronic infection and serious liver damage. Bed rest and fluid intake are not sufficient treatments for Hepatitis C.

3. Hepatitis C is an emerging communicable disease of epidemic proportions.
   This statement is correct. Hepatitis C is a significant global health issue, with millions of people affected worldwide. It is considered a major public health concern due to its potential to cause chronic liver disease and its widespread prevalence.

4. Hepatitis C has decreased dramatically since the development of a vaccine in the 1990s.
   This statement is incorrect. There is no vaccine for Hepatitis C. Efforts to reduce its prevalence focus on prevention, early detection, and treatment with antiviral medications.

In summary, Hepatitis C is a major public health concern due to its potential to cause chronic liver disease and its widespread prevalence, making the third statement the correct one.
