question 10

Multiple Choice

Use the following information to answer the question.
The herpes viruses are important enveloped DNA viruses that cause disease in vertebrates and in some invertebrates such as oysters. Some of the human forms are herpes simplex virus (HSV) types I and II, causing facial and genital lesions, and the varicella zoster virus (VSV) , causing chicken pox and shingles. Each of these three actively infects nervous tissue. Primary infections are fairly mild, but the virus is not then cleared from the host; rather, viral genomes are maintained in cells in a latent phase. The virus can later reactivate, replicate again, and infect others.
If scientists are trying to use what they know about the herpes simplex virus to devise a means of protecting other people from being infected, which of the following treatments would have the best chance of lowering the number of new cases of infection?

• A) Vaccinate of all persons with preexisting cases of herpes simplex virus.
• B) Interfere with new viral replication in preexisting cases of herpes simplex virus.
• C) Treat herpes simplex virus lesions to shorten the breakout.
• D) Educate people about avoiding sources of infection.
