A little over one third of Internet users in the EU (36.4%) and nearly 30% in the NAS countries reported online searching for health-related information during the 12 months reference period. Although this is a substantial figure, it is a lot lower than the more than almost three in five (58.3%) of the US sample who reported this form of eHealth activity. Within Europe, the prevalence of reported online health information seeking amongst Internet users varied considerably across the countries, with highest rates in Ireland (48.1%) and lowest rates in Greece (21.6%).
