The eBarometer is a digital platform that provides predictive, tailor-made and actionable alerts to various audiences on the ground, from healthcare authorities to citizens. It will dramatically increase efficiency in the fight against dengue, helping people to actively prepare for future outbreaks, implementing the best possible actions, and therefore reducing the annual human and economic burden of the disease. In 2019 we started building sections of the eBarometer, together with a team of Google volunteers, and we now have a strong basis to move forward, with all the required expertise and local support in endemic countries.
