"Eight tips for using Twitter around health-related events" was first prepared by @francetim (Inis Communication) and @GlobalHealthTom in collaboration with CNS and was launched at the 11th International Conference on AIDS in Asia and the Pacific. Since then it has adapted and used by delegates of various health-related events around the world (and those not attending but following these events online). Most recently it was adapted and disseminated by Union International for Cancer Control (UICC)/ World Cancer Day, Inis Communication and CNS. This brief guide provides eight simple tips to make the most of one social media platform – Twitter – around the World Cancer Day (4th February 2014). Please contact Inis Communication for getting this guide adapted to your health event!
