The brand is preparing to roll out MyAchoo, which Kleenex Brand Manager Anna Elledge says is a proprietary forecasting model using Centers for Disease Control data. It will live at MyAchoo.com starting later this month. It goes beyond other cold and flu trackers like Google Flu Trends or the Cold-FX app, by predicting where germs will strike within the next three weeks -- not just showing where they already are, Ms. Elledge said. Preliminary tests suggest the tool is 90% accurate, she said.
