ADH Flu Report

ADH Flu Report

Arkansas continues to see widespread cases

www.healthy.arkansas.gov During the flu season the Arkansas Department of Health (ADH) produces a Weekly Influenza Report for clinicians. The report provides information on flu activity in the state. The report also compares influenza like illness (ILI) in Arkansas to activity in the U.S. ADH receives reports of only a fraction of flu cases. Therefore, it is important to understand that the information in the weekly update is representative of the timing and location of activity, but it does not reflect the overall burden of disease. It is presumed that there are many more people actually affected than the report shows. Clinicians and policy makers may find the report helpful in terms of communicating to colleagues and patients about the current status of the flu season.
