Antiretroviral drugs are effective at blocking HIV replication in infected individuals, and in reducing the rate of HIV transmission. Physical barriers to transmission have also been shown to be effective at blocking HIV transmission. An additional strategy for reducing the rate of new HIV infections in high-risk populations utilizes a strategy to prevent the virus from establishing a permanent infection, once an individual has been exposed. This strategy utilizes:
A) Weekly injections of neutralizing anti-HIV antibodies
B) Pre-exposure prophylactic treatment with antiretroviral drugs
C) Condoms
D) Distribution of sterile hypodermic needles and syringes
E) Heat-killed HIV as a vaccine

Question

Quizplus · Accepted Answer

Pre-exposure prophylactic treatment with antiretroviral drugs has been shown to be effective in preventing the establishment of a permanent HIV infection in high-risk populations. This involves taking antiretroviral drugs before potential exposure to HIV, in order to prevent the virus from replicating and establishing an infection in the body. This approach has been particularly effective in reducing new HIV infections among individuals who engage in high-risk behaviors, such as injection drug use or unprotected sex.
