Dear authors, speakers and all contributors, Regarding the growing concern about the international coronavirus outbreaks we’ve made the decision to Postpone the organization of the ICT-DM'2020 conference, which was planned for December in Tunisia, to 2021. For reasons of credibility and to ensure the quality of the conference, we need to ensure the participation of all authors, guest speakers and guests of honour on site. We are really annoyed and disappointed that we cannot welcome you at the moment.Above all, we hope that you and your loved ones are doing well and that this pandemic will be defeated very quickly.All the best.The ICT-DM steering committee
