Influenza-like Illness (ILI) Case Definition

A fever greater than or equal to 100.0° F or 37.8° C

    - This can include an oral temperature or equivalent


A cough and/or sore throat

    - In the absence of a known cause other than influenza


Influenza Sentinel Surveillance Program

The Wyoming Influenza Sentinel Surveillance Program is a partnership between local clinicians, the Wyoming Department of Health (WDH) and the Centers for Disease Control and Prevention (CDC) to conduct surveillance ILI. This program is an important part of our surveillance efforts to track both ILI and influenza. The sentinel provider program involves two major components, which are described below.

Weekly Influenza-Like Illness (ILI) Reporting: Consists of recording and reporting summary data each week to CDC via the internet. The summary data includes the total number of patient visits for any reason and number of patient visits for ILI by age group. Reports are submitted each week, even when no ILI activity is observed.

Laboratory Surveillance: Consists of collecting specimens from patients with ILI; the specimens are sent to the Wyoming Public Health Laboratory (WPHL) for influenza testing.  


Laboratory Surveillance

Prior to the start of each influenza season, the WPHL will send influenza kits to the network of influenza sentinel surveillance providers. Each year, sentinel providers from all over the state use the influenza kits to submit specimens to the WPHL for influenza testing. Influenza kits contain the following: Laboratory Requisition Form, Laboratory Protocols and Influenza Virus Collection Kits.


Laboratory Submission Recommendations

Influenza Sentinel Surveillance Providers may submit specimens on all ILI cases or on a sample of ILI case. However, the WPHL and Infectious Disease Epidemiology Section offer the following laboratory submission recommendations:

1.    Submit specimens from patients that meet the ILI case definition.

-          Submitted specimen should meet the ILI case definition. However, it is permissible to submit specimens on cases that do not meet the ILI case definition.

2.    Submit specimens weekly to the Wyoming Public Health Laboratory for specialized testing.

-          If it is difficult to submit specimen on cases that meet the ILI case definition, the providers can use their discretion when deciding which samples to submit for testing.

3.    Submit specimens on patients with severe disease.

-          Specimens should be submitted on all hospitalized ILI cases.
