There is an influenza division of the CDC whose responsibility it is to keep track of influenza activity year round. This group compiles and analyzes known cases in order to help states and local governments respond accordingly. The CDC establishes seasonal baselines on what they expect to see in regards to flu & pneumonia related deaths in a given week. For the week ending January 30, the seasonal baseline was 29.3% and the actual rate was 17.4%, meaning that the week was below the seasonal baseline. Figures can change and counts can be adjusted as new information is learned from each patient.
