HIV Treatment as Prevention Worked in Australia

This year, the annual Conference on Retroviruses and Opportunistic Infections (CROI) was held in a virtual format due to the COVID-19 coronavirus outbreak. In his virtual presentation, Denton Callander, PhD, of the University of New South Wales in Sydney, explained how community-level HIV viremia was associated with decreasing HIV incidence in a real-world example of the population-level impact of “treatment as prevention” in two large Australian states.

In this exclusive MedPage Today video, Callander explains how treatment as prevention at an individual level works well, although the big picture effects of this strategy are less clear — including whether public health outcomes follow the benefits for individuals.

Following is a transcript of his remarks:

Hi, my name is Denton Callander, and I am an HIV and sexual health researcher with the University of New South Wales. Earlier in March this year, I presented on behalf of my colleagues at the virtual CROI conference, which is normally held in Boston but was conducted online this year. And I shared with participants an analysis that my colleagues and I have been working on, really representing a project that’s been running for a number of years now that aims to investigate HIV treatment as prevention and its effects on HIV incidents. We’ve known of course for a number of years now that HIV treatment is really great for individual health and also between individuals it’s quite an effective prevention tool. So if you’re on treatment, you’re not going to pass on the virus.

During the Canada Post strike announced September 25, 2025, the following measures will be undertaken to minimize service disruption to BC-CfE clients and providers.

  • The BC-CfE Laboratory has transitioned to private courier for delivery of outgoing reports and documents. Results required urgently can be faxed upon request. (Lab Contact Information: Phone 604-806-8775; FAX 604-806-9463)
  • The BC-CfE Drug Treatment Program (DTP) will fax outgoing forms and documents to the provider’s office. (DTP Contact Information: Phone 604-806-8515; FAX 604-806-9044)
  • St. Paul’s Hospital Ambulatory Pharmacy has transitioned to private courier for delivery of medications. We recommend requesting medication at least 2 weeks in advance in case of delivery delays, particularly to rural/remote parts of BC. (Contact Information: Phone 1-800-547-3622; FAX 604-806-8675)

During the Canada Post strike, we recommend that documents be faxed or couriered to our sites, versus utilization of regular mail service

The BC-CfE Laboratory is streamlining reporting processes for certain tests in order to simplify distribution and record-keeping, and to ensure completeness of results. Beginning September 2, 2025, results for the ‘Resistance Analysis of HIV-1 Protease and Reverse Transcriptase’ (Protease-RT) and ‘HIV-1 Integrase Resistance Genotype’ tests will be combined into a single ‘HIV-1 Resistance Genotype Report’.
