Zoltan Dezso with Reka Albert at the Americal Physical Society March Meeting in Indianapolis. Dezso has been the author of the paper [REF] suggesting that by curing the promisous individuals we can lower the prevalence of the AIDS epidemic, and would return the threshold. Similar results were obtained by Pastor-Satorras and Vespignani.
