Source: U.S. Centers for Disease Control and Prevention (CDC). Data is based on influenza-like illness (ILI) activity as reported by state outpatient healthcare providers. ILI is defined as fever and cough and/or sore throat with influenza as the only known cause. Weekly reports are published approximately 10-12 days after the week ending date, due to the time required to compile national data.
