Google is gradually shifting towards providing Health applications with the latest being created Google Dengue Trends, a precautionary system to monitor dengue-related search terms in Bolivia, Brazil, India, Indonesia and Singapore. The aim of the company is to develop an early-warning system with the help of this service. This service will allow the user to track the dengue fever hubs by monitoring search patterns and help the heath officials prepare for outbreaks. The online surveillance over dengue-related search by users in Bolivia, Brazil, India, Indonesia and Singapore shows that using the dengue case count data provided by Ministries of Health and the World Health Organization, the company is able to build a model that offers near real-time estimates of dengue activity based on the popularity of certain search terms. In 2009, Google developed an early warning system for flu outbreak by keeping track of users searching for information about the virus.
