Q

What retrovirus does not cause disease in humans?

A

Spumavirus

20
Q

How does a retrovirus go about replicating its genome?

What virus has a diploid (+)ssRNA genome?

A

Retrovirus

22

A

HTLV-1

24
Q

Which virus targets CD4+ memory T-cells and can lead to many oppurtunistic infections and wasting?

A

HIV (AIDS)

25
Q

How is AIDS controlled?

A

AZT and cocktail of antivirals

26
Q

Which virus can only infect other cells via cell-cell interaction and is often spread through breastfeeding?

A

HTLV-1

27
Q

What types of viruses result in permanent integration into the host cells DNA that can lead to cancer?

A

Retrovirus

28
Q

What type of virus must contain at least the following genes: Gag, Pro, Pol, Env?

A

Retrovirus

29
Q

What virus does Tamiflu inhibit and how does it do it?
