Answer 1

C) It is also known as the “DELTA VIRUS HELICAL NUCLEOCAPSID.”

Question 2

How is Hepatitis D primarily transmitted?

A) Through respiratory droplets
B) Through contaminated food and water
C) Parenterally and can replicate with the help of HBV
D) Through sexual contact

Answer 2

C) Parenterally and can replicate with the help of HBV

Question 3

What is the characteristic feature of Hepatitis D?

A) It is an enveloped DNA virus
B) It is a single-stranded RNA virus
C) It is a completely independent virus with no interactions with other viruses
D) It is a defective hepatotropic virus that relies on HBV for replication and infectivity

Answer 3

D) It is a defective hepatotropic virus that relies on HBV for replication and infectivity

Question 4

Which of the following describes a type of infection carried out by HDV?

A) Co-infection with hepatitis A
B) Co-infection with hepatitis C
C) Co-infection with hepatitis B
D) Co-infection with hepatitis E

Answer 4

C) Co-infection with hepatitis B

Question 5

What is superinfection with hepatitis B in the context of HDV infection?

A) It is a milder form of HDV infection
B) It leads to no change in the course of HDV infection
C) More severe HDV infection that occurs alongside existing hepatitis B infection
D) It is a protective response to HDV infection

Answer 5

C) More severe HDV infection that occurs alongside existing hepatitis B infection

Question 6

Which of the following statements is true regarding the serologic marker HDV ag (Hepatitis D virus antigen)?

A) HDV ag is typically found in the late stage of HDV infection.
B) HDV ag is a reliable and persistent marker in plasma throughout the infection.
C) HDV ag is found in the early stage of infection but rapidly disappears in plasma.
D) HDV ag is not associated with HDV infection.

Answer 6

C) HDV ag is found in the early stage of infection but rapidly disappears in plasma, which is not very useful.

Question 7

Which serologic markers are used for detecting the acute phase of HDV infection?

A) IgM anti-HDV and total anti-HDV (IgM & IgG)
B) IgG anti-HDV only
C) IgM anti-HDV only
D) HDV RNA

Answer 7

A) IgM anti-HDV and total anti-HDV (IgM & IgG)

Question 8

What does the presence of IgM anti-HDV and HBsAg together with IgM anti-HBc indicate in serologic markers for HDV?

A) Chronic HDV infection
B) Acute HDV infection
C) Co-infection
D) Past HDV infection

Answer 8

C) Co-infection

Question 9

What does the absence of IgM anti-HBc indicate in serologic markers for HDV?

A) The patient is immune to hepatitis B.
B) The patient has acute hepatitis B infection.
C) The patient is chronically infected with hepatitis B.
D) The patient has superinfection with hepatitis B.

Answer 9

D) The patient has superinfection with hepatitis B.

Question 10

What does the presence of anti-HDV IgG indicate in the context of HDV infection?

A) Acute infection
B) Past infection
C) Chronic infection
D) Vaccination

Answer 10

C) Chronic infection
