2004 - 2005 Texas Influenza Surveillance Information
The weekly flu activity level for CDC week 11 ending 3/19/05 remains regional.
Reports were received for all eleven regions.
Flu activity has continued to decline again this week.
The region representing South Central Texas (HSR 8) reported increased activity over last week, although this may be due to the return of students from Spring Break and a lull in reporting last week. The two regions representing East Texas (HSRs 4, 5N) reported about the same (high) level of flu activity as last week. The regions representing the panhandle (HSR 1) and the Houston/Galveston area (HSR 5S/6) reported about the same (decreased) level of flu activity as last week. The six regions representing Northeast Texas (HSRs 2/3), Central Texas (HSR 7), West Texas (HSRs 9/10), and South Texas (HSR 11) reported decreasing flu activity.
