2005 - 2006 Texas Influenza Surveillance Information

The flu activity level for the week ending May 20, 2006 remains at no activity. This does not mean that flu is not occurring in the state, but rather, at very low levels.

Reports were received from all 11 Health Service Regions (HSRs) for week 20. Only HSR 1 reported an increase in flu activity. Limited flu activity was reported in HSRs 1, 6/5S, 7, 8, and 11. HSRs 2/3, 4/5N, and 9/10 reported no flu activity. For a map of Health Service Regions, please visit the following website:

During week 20, no culture confirmed influenza A or B was identified by the DSHS laboratory or reported by any other laboratories in the state.

No institutional outbreaks or school closures were reported for week 20.

The official reporting period for flu has ended. This is the last flu report for the 2005-2006 season for the state. The 2006-2007 reporting season begins the week ending October 7, 2006 (week 40). A summary of the 2005-2006 season will be posted on the IDCU website in the coming months.

***Providers should continue to consider flu as a possible diagnosis and submit specimens to the DSHS laboratory even after flu season has ended. Unusual occurrences of respiratory illness should be reported to either the state or a local health department.

A big “thank you” to all those providers, schools, laboratories, and healthcare professionals at the regional and local level who participated in flu surveillance activities during the 2005-2006 season.

We couldn’t have done it without you!
