Influenza Surveillance Report for MMWR Week 42

The influenza (flu) activity level for Texas for the week ending October 18, 2008 was “sporadic.” Sporadic activity indicates that isolated reports of lab-confirmed influenza along with influenza-like illness have been reported. During week 42, one (2.5%) specimen tested by NREVSS laboratories in Texas was positive for influenza; the first positive culture of the season was also reported. Flu is occurring in the state at a very low level.


Reports from Health Service Regions

Reports were received from all Health Service Regions (HSRs) for week 42. HSR 7 reported an increase in flu activity compared to week 41; all other HSRs reported the same level of flu activity compared to week 41. For a map of Health Service Regions, please visit the following website:


Laboratory Results

During week 42, four hospital laboratories across Texas reported conducting a total of 40 influenza tests (antigen, culture, and PCR) to the National Respiratory and Enteric Virus Surveillance System (NREVSSnew window)sponsored by the Centers for Disease Control and Prevention (CDC). Thirty-two antigen detection tests for influenza were performed; one test in Nueces County was positive for influenza A/not subtyped. The first positive flu culture of this season was reported by Scott & White Memorial Hospital in Temple during week 42. The specimen, obtained from an unvaccinated (for influenza), 14-year-old Bell County resident, was positive for influenza A/not subtyped. The isolate will be forwarded to the DSHS lab in Austin for subtyping. No positive PCR results were reported. Positive point-of-care rapid tests for influenza were reported by providers throughout the state (see county map below).
