The findings may help explain the results of some community-based prevention studies and help scientists find better ways to track and prevent the spread of HIV
Early detection and treatment of HIV can help prevent the spread of the virus
"To curb the spread of new HIV infections, we need to better understand HIV transmission patterns in the region," said lead author Lerato Magosi, a postdoctoral fellow at the Center for Infectious Disease Dynamics at the Harvard Chan School of Public Health in Boston, USA
Magosi and his colleagues set out to study HIV transmission patterns in Botswana, Africa
By identifying genetically closely related HIV samples, the team was able to track how the virus spreads within and between these communities
Magosi explained: "Our findings suggest that community-based HIV testing and treatment initiatives are powerful tools for reducing HIV transmission, but targeted research support is needed to bridge age and gender access to testing and treatment.
The authors suggest that genetic sequencing could be a valuable tool to help determine geographic patterns of HIV transmission
