The purpose of the influenza statistics page is to provide summaries of influenza information obtained from the Oklahoma State Department of Health (OSDH) influenza sentinel surveillance system, and influenza test results from the OSDH Public Health Laboratory (PHL).
Note: The last week of the 2012-2013 influenza season will be the week ending April 27, 2013. The Acute Disease Service (ADS) will continue to partner with healthcare providers and hospital laboratories throughout the summer to conduct influenza and viral respiratory sentinel surveillance. From June through September 2013, ADS will produce a monthly report, and updated influenza statistics will be posted on the first Thursday of each month by 10:00 a.m.
