EPSTEIN-BARR VIRUS

Question 1

What group of viruses does EBV belong to

Answer 1

Human herpesvirus

Question 2

What cell is first infected by EBV

Answer 2

Epithelial cells

Question 3

What type of viral infection is EBV

Answer 3

Latent

Question 4

What is acute infection

Answer 4

virus undergoes multiple rounds of replication. Replication results in the death of the host cell, which is used as a factory for virus production. Examples of acute infections are those caused by poliovirus or influenza virus.

Question 5

What is latent infection

Answer 5

The persistence of viral DNA either as an extrachromosomal element or as an integrated sequence within the host genome

During cell growt the genome of the virus is replicated along with the chromosome of the host cell

Question 6

Chronic infection

Answer 6

Release of virus particles sometimes without death of the host cell or overt cellular injury

Associated with defective host immune responses that are insufficient to clear the infection
