Influenza Surveillance Report for MMWR Week 44

The influenza (flu) activity level for Texas for the week ending November 1, 2008 was “sporadic.” Sporadic activity indicates that isolated reports of lab-confirmed influenza along with influenza-like illness have been reported. During week 44, seven (1.4%) specimens tested by NREVSS laboratories in Texas were positive for influenza. Flu is occurring in the state at a very low level.

Reports were received from all Health Service Regions (HSRs) for week 44. HSR 1 reported an increase in flu activity compared to week 43; HSR 7 reported a decrease in flu activity.

Four hundred and sixteen antigen detection tests for influenza were performed; five tests in Bexar and Nueces counties were positive for influenza A/not subtyped. No positive PCR results were reported. Two specimens collected from a 1-month-old child and a 14-year-old child, both residents of Bexar County, were positive by viral culture for influenza A/H1.
