Google.org has launched Google Flu Trends to provide up-to-date estimates of flu activity in the United States based on aggregated search queries.
Search queries related to flu can be viewed at the United States level or on a state by state basis.
Based on search data from years past, flu season in the United States begins in mid November and ends by early April depending on where you are located.
Search Google Flu Trends to see your particular state’s historical and present flu search activity.
Overall, California appears to have less search activity than other states during flu season.
While most other states appear to share the same flu season with the exception of Maine and Texas.
Maine’s flu search interest appears to indicate Maine has a longer flu season than other states.
While flu season in Texas appears to start later and end more quickly than in other states.
Check back with Google Flu Trends after you have had Thanksgiving Dinner to begin monitoring when flu search activity increases and thus when flu season has begun in your state.
