Welcome to the 5th International Conference on Digital Health (www.acm-digitalhealth.org), held in conjunction with the 24th International World Wide Web Conference (WWW 2015) and in-cooperation with ACM Special Interest Group on Management of Data (SIGMOD) and Special Interest Group on Knowledge Discovery and Data Mining (SIGKDD) in Florence, Italy from 18th May 2015 until 20th May 2015. The 5th International Conference on Digital health 2015 is building on the great success of the 1-4th International conference on eHealth series (http://www.electronic-health.org/) featuring events in London in 2008, Istanbul in 2009, Casablanca in 2010 and the 4th eHealth 2011 taking place in Malaga with high profile presence from WHO and ECDC. It further follows on the International Workshop on Public Health in the Digital Age (1st PHDA 2013 and 2nd PHDA 2014) building a community of public health informatics professionals. With ACM support, collocation with WWW 2015 and expanded programme, the rebranded 5th DH 2015 promises to deliver a prime international interdisciplinary event bringing together frontline public health professionals and computer science researches in data mining, crowdsourcing and Big Data analysis for public health surveillance. To better embrace the growing digital health domain, the 5th DH 2015 is organized into more independent Tracks with proceedings printed by ACM Digital Library. Collocation with WWW 2015 promises to attract computer scientists to public health data management and analytics challenges, we are also inviting a wider industry, start-ups and medical audience. Keynote speakers include Alberto Sanna, the Director of eServices for Life and Health, Scientific Institute San Raffaele, Italy will deliver a talk on "Engineering Awareness: Health & Wellbeing Services in Socio-technological Ecosystems".
