Texas Influenza Surveillance Summer Report

Current Extended Flu Activity Report (PDF)
(September 23, 2018 – September 29, 2018)
Report produced on 10/05/2018

Summary:
Influenza activity remains low across the state of Texas. It appears that influenza activity peaked in late January. Compared to the previous week, the percentage of patient visits due to influenza-like illness (ILI) and the percentage of specimens testing positive for influenza reported by public health laboratories slightly increased. The percentage of specimens testing positive for influenza reported by hospital laboratories marginally decreased. No influenza-associated pediatric deaths were reported. One influenza-associated outbreak was reported. In addition to flu, other respiratory viruses—especially rhinovirus/enterovirus—were detected in Texas during week 39.

Hospital laboratories across Texas voluntarily report influenza tests (antigen, culture, and PCR) to the National Respiratory and Enteric Virus Surveillance System (NREVSS). Providers throughout Texas also submit specimens for influenza testing (PCR) to Texas public health laboratories, including the Texas Department of State Health Services (DSHS) state laboratory in Austin and the nine Texas Laboratory Response Network (LRN) laboratories. The results reported by Texas NREVSS participants and public health laboratories for the current week are summarized in the two tables below. Additional influenza test results (rapid tests, culture, PCR) and ILI activity were reported from providers and public health departments throughout the state.
