HIV spreads like internet malware and should be treated earlier

A new model for HIV progression finds that it spreads in a similar way to some computer worms and predicts that early treatment is key to staving off AIDS.

HIV specialists and network security experts at UCL noticed that the spread of HIV through the body using two methods – via the bloodstream and directly between cells – was similar to how some computer worms spread through both the internet and local networks respectively to infect as many computers as possible. They worked together to create a model for this ‘hybrid spreading’, which accurately predicted patients’ progression from HIV to AIDS in a major clinical trial. (more…)
