The athenaInsight Flu Dashboard

Loading iframe…

athenaInsight is tracking the spread of the flu across the United States this season, using athenahealth’s network to measure influenza-like symptoms across 1 million patient visits per week to more than 25,000 pediatricians, primary care providers, and emergency medical providers. Use the interactive graphic above to hone in on a state or a single week, and check back weekly for updated data.

Our methodology: Using diagnosis codes from insurance claims data at the state and national level, the dashboard quantifies how many patients with influenza-like illness (ILI) are seen by each provider and estimates the proportion of symptomatic patients seen by providers around the country. The Centers for Disease Control and Prevention defines influenza-like illness as either a specific diagnosis of influenza or a fever co-presenting with a cough or sore throat.
