By using data from routine testing about the genetic evolution of the HIV /AIDS virus in the Canadian province of British Columbia, researchers have shown they are able to identify emerging outbreaks of the disease in near real-time and intervene to control its spread. The first-of-its-kind system is the focus of a study in an April edition of The Lancet HIV. We spoke to Art Poon, Associate Research Scientist for the British Columbia Centre for Excellence in HIV/AIDS and lead author of the study, about the monitoring system, the impact it has had, and whether such an approach is transferable to other regions and other disease outbreaks.
