Weekly Influenza Report 

During 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 US.   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.  

For Week 10, ending March 14, Arkansas reported “Regional” flu activity to the CDC.  Over 200 positive antigen reports were received from 38 counties. The predominant influenza viruses identified by antigen testing were Type B. Among flu antigen tests that can distinguish between A and B strains, 32% were Type A and 68% were Type B.  Thirty-one samples reported were reported as Positive for influenza by PCR testing:  1 Type A+, 4 Type A H3+, 18 Type B+, 3 Type B-Victoria, and 5 Type B-Yamagata.

For Week 11, ending March 21, Arkansas reported “Regional” flu activity to the CDC.  Over 400 positive antigen reports were received from 54 counties. The predominant influenza viruses identified by antigen testing were Type B. Among flu antigen tests that can distinguish between A and B strains, 22.5% A and 77.5% B.  Fourteen samples reported last week were confirmed Positive for influenza by PCR testing; 1 A, 11 B, and 2 B Yamagata. Arkansas has had 54 influenza-related deaths this flu season.
