Which mode of transmission is associated with hepatitis A?

Choice C rationale:

Interferon-alpha may be prescribed for the treatment of chronic hepatitis B infection. It is an antiviral agent that can help boost the immune system's response to the virus and inhibit viral replication.

Choice D rationale:

Entecavir is an antiviral medication that is commonly used to treat chronic hepatitis B infection. It works by inhibiting viral DNA polymerase, thereby reducing viral replication.

Choice E rationale:

Telbivudine is another antiviral agent that may be prescribed for the treatment of chronic hepatitis

B. It works by inhibiting reverse transcriptase, an enzyme necessary for viral replication.

Choice A rationale:

This statement is incorrect. Chronic hepatitis is a condition where liver inflammation lasts for more than six months. If hepatitis lasts less than six months, it is referred to as acute hepatitis.

Choice B rationale:

This statement is incorrect. Chronic hepatitis can be caused by enveloped single-stranded RNA viruses, specifically hepatitis B and C viruses. Non-enveloped single-stranded RNA viruses, like the norovirus, can cause acute gastroenteritis, but not chronic hepatitis.

Choice C rationale:

This statement is correct. Chronic hepatitis, particularly caused by hepatitis B and C viruses, can lead to serious complications such as liver cirrhosis, liver failure, and liver cancer. It is essential to manage chronic hepatitis carefully to prevent these severe outcomes.

Choice D rationale:

This statement is incorrect. Chronic hepatitis is not primarily transmitted through the fecal-oral route. Hepatitis A virus is transmitted through contaminated food or water and primarily spreads through the fecal-oral route. Hepatitis B and C viruses are commonly transmitted through blood contact, sexual contact, and from an infected mother to her baby during childbirth.
