CDC Publishes Latest Evidence for Key HIV Prevention Strategies

September 13, 2019


July 19, 2019
The Centers for Disease Control and Prevention (CDC) has updated its webpage titled “Effectiveness of Prevention Strategies to Reduce the Risk of Acquiring or Transmitting HIV.” The webpage features tables that summarize the latest evidence for key HIV prevention strategies such as anti-retroviral therapy (ART), pre-exposure prophylaxis (PrEP), and condoms.
There are now more options than ever before to effectively reduce a person’s risk for acquiring or transmitting HIV. But in order to provide maximum prevention benefit, these strategies must be used correctly and consistently. When taking PrEP daily, PrEP is about 99% effective in preventing HIV acquisition during sex. For persons taking ART as prescribed and achieving and maintaining viral suppression, there is effectively no risk of transmitting HIV through sex. Consistent and correct condom use is highly effective at preventing HIV, although the prevention effectiveness for condom use varies by population.
These updated tables reflect the most recently published scientific literature and provide the effectiveness of each strategy when used optimally.
