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.
Influenza activity has increased significantly in Arkansas for Week 50. About 800 Positive antigen reports were received last week from 61 counties. Among the antigen tests that can distinguish between Type A and B strains, 84% were A, and 16% were B. Fifteen samples were confirmed Positive last week for influenza by PCR testing: eight A+, four A H3+, one B Victoria, and one B Yamagata.
