Influenza Testing & Surveillance
Bureau of Laboratories
Novel Influenza A (H1N1)
2009
For the fall 2009 Influenza Season, the MDCH Bureau of Laboratories is NOT performing diagnostic testing for 2009 novel influenza A, H1. We will be testing only for public health case investigations (ICU hospitalizations, severly ill pregnant women, patients with unusual and severe presentations, deaths) and for congregate setting outbreak/cluster investigations along with surveillance testing through the Michigan Sentinel Physician and Sentinel Laboratory Programs. See the MDCH 2009-2010 Influenza Testing Algorithm for details.
For the most current updates, see the latest MIFluFocus report

For the latest information on the outbreak, see the MDCH Influenza Page or the Lab's Novel Influenza page.

2009-2010 Influenza Season Report
The data shown here are the results obtained by the MDCH Virology Laboratory from specimens for targeted public health testing plus surveillance testing through the Michigan Sentinel Physician and Sentinel Laboratory Programs. The Sentinel Physician Program consists of medical provider sites from a variety of geographic locations throughout Michigan enrolled in the sentinel surveillance program. These providers represent private practice for adult and pediatric patients, as well as urgent and emergency care facilities, nursing homes and university health services. Michigan is now conducting routine influenza surveillance year round. Thus, MDCH requests submission of two to three specimens for influenza A and B viral culture four times during the year: early influenza season, when influenza virus is beginning to circulate; middle season, during the peak of influenza activity; late season, as influenza activity diminishes; and in the summer months. Participation in this program is voluntary.
The influenza season runs from October through the end of September each year.

To expedite receipt of laboratory results, we urge all submitters to register for fax transmittal of reports. Fax agencies receive their reports the day testing is completed. This is especially important for those submitting specimens for H5 PCR testing. Non-fax agencies receive reports via the U.S. Post Office. This method will delay your report by several days. Registration information.
