Influenza in Alabama
For the week ending November 19, the geographic spread of influenza-like illness (ILI) in Alabama was local. Local spread indicates that the percentage of patients with reported ILI was significantly high in one of the eleven Public Health (PHAs), and there were positive influenza specimens from the same PHA within the past three weeks to support influenza being a cause of ILI in the area. The influenza strain identified in the last three weeks included influenza A (H3).
- To review the geographic spread of ILI in Alabama, please visit the Influenza Surveillance Map (this map works best with recent supported versions of Google Chrome, Internet Explorer 11, Mozilla Firefox, Safari, Opera, and many mobile devices).
- A graph displaying ILI data and positive influenza specimens submitted to the Bureau of Clinical Laboratories (BCL) is also available.
Influenza-Like Illness (ILI) Data
As part of the Centers for Disease Control and Prevention's U.S. Outpatient Influenza-Like Illness Surveillance Network (ILINet), ADPH has recruited 84 healthcare providers to report the number of patients with ILI by age group and the total number of patients seen for the week. These providers are located in every public health area and almost every county. 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. There is no requirement for a positive influenza test (in the absence of a known cause other than influenza) when determining the number of patients with ILI.
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.
