Skip to main content to expand Google Flu Trends tracking


MOUNTAIN VIEW, Calif. on Tuesday announced on its blog site that it is expanding its Google Flu Trends tracking capabilities from the macro to the micro.

“We've been chatting with public health officials about new ways we can help people understand the spread of flu during this unusual time and today we're excited to bring city level flu estimates to 121 cities in the United States,” the company wrote in its blog.

The city level estimates are "experimental," the company cautioned, meaning they haven't been validated against official data. However, the estimates are made in a similar manner to its U.S. national estimates, which have been validated.

In contrast to the unusually early spike of flu activity this October, Google Flu Trends is currently showing a low level of activity in the United States.

Google Flu Trends helps estimate flu trends in real time by tracking the popularity of certain Google search queries.
