It is not too late to get vaccinated! For those who have not received their annual influenza shot, the quadrivalent vaccine, which protects against four (quad) strains, is the only vaccine available that provides protection against Influenza B (Yamagata).
Influenza-Like Illness (ILI) Data
As part of the CDC’s U.S. Outpatient Influenza-Like Illness Surveillance Network (ILINet), healthcare providers in Alabama report the number of patients with ILI by age group and the total number of patients seen each week. ILI is defined as fever that is greater than or equal to 100 degrees Fahrenheit (37.8 degrees Celsius) AND cough and/or sore throat (in the absence of a known cause other than influenza). There is no requirement for a positive influenza test when determining the number of patients with ILI.
No outbreaks of influenza or ILI were reported in the state this week.
The chart below indicates ILI activity is decreasing through much of Alabama.

Viral Surveillance
ADPH's viral surveillance depends on hospitals and healthcare providers to voluntarily submit specimens from ILI patients to BCL throughout the year for influenza detection and subtype information. Influenza specimen submissions from healthcare providers help answer the questions of where, when, and what influenza viruses are circulating. ADPH requests that hospitals submit specimens for admitted patients with ILI and all physicians submit specimens for pregnant patients with ILI, as well as recent international travelers with ILI.
Any provider can submit influenza specimens for BCL testing. To find out more about ordering a flu kit, specimen collection, and shipping instructions, see the Quick Guide for Influenza Specimen Submission or the detailed Guidance for Lab Testing for Influenza Viruses.
