The Centers for Disease Control have a variety of surveillance measures to analyze medical data to detect or anticipate disease outbreaks. Well, Google has one, too.
Google Flu Trends is a Google service that tracks the occurrence of flu across the United States based on the number flu-related searches made in areas around the country. It actually has been very accurate at tracking flu cases, with their statistics matching closely to the CDCs resources, and often times, measuring outbreaks one to two weeks quicker.
This year, flu rates have been at low to moderate levels in each state, including Florida which has seen a moderate amount of flu cases since the end of September.
