Welcome to ADPH's Influenza Surveillance website. ADPH is monitoring which strains are circulating and where disease activity is occurring.

ADPH has a list of 10 things you can do to fight the flu.

Influenza in Alabama

For the week ending November 29, the geographic spread of influenza-like illness (ILI) in Alabama was regional.  This level indicates that there were either reported outbreaks of influenza or that the percentage of patients with reported ILI was above baseline in more than one but less than six public health areas (PHA) and there were lab confirmed cases of influenza within the past three weeks from the same PHAs. In the past three weeks, there have been 17 influenza specimens submitted to the Bureau of Clinical Laboratories (BCL) for influenza testing. Sixty-five percent of submitted specimens tested positive for influenza. The influenza strains identified in positive specimens included influenza A, H3 and influenza B.

During the 2013-2014 influenza season Alabama observed a peak in reported ILI during the month of December. There were 16 ILI, influenza, or unknown respiratory outbreaks reported to and investigated by ADPH over the influenza season. The predominant influenza strain identified in specimens submitted to the BCL was 2009 influenza A, H1N1. Influenza B and Influenza A, H3 were identified in specimens between mid-February and May. 

For a view of the geographic spread of ILI in Alabama, please visit the Alabama Influenza Surveillance Map.

Influenza Control and Outbreak Guidelines

Influenza-Like Illness (ILI)

As part of the Centers for Disease Control and Prevention's U.S. Outpatient Influenza-Like Illness Surveillance Network (ILINet), Alabama 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.

If you are interested in becoming an ILINet participant, please email the Division of Epidemiology, call 1-800-338-8374, or complete and fax the ADPH Influenza-like Illness Network (ILINet) Application.

Viral Surveillance

ADPH's viral surveillance depends on hospitals and healthcare providers to voluntarily submit specimens from ILI patients to the Alabama Bureau of Clinical Laboratories 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 specimen collection and shipping instructions, see the Quick Guide or the detailed Guidance for Laboratory Testing for Influenza Viruses.
