Please note that CHSN Flu Tracking weekly reports will resume in mid-January 2015.

In the week 12 report of influenza activity on campuses in the College Health Surveillance Network, all 11 schools report 1 or more influenza-like illness cases. One school in the Northeast, two in the South, and one in the Midwest region had a percentage of cases that crossed the threshold of a CDC defined outbreak. At least one school in each region had a reported case.

The graphic above shows ILI visits, both as an absolute number and as a percent of total primary care visits; the table below shows the data for each reporting school and totals by Census Region.
