RSV Data

Respiratory syncytial virus, or RSV, is a respiratory virus that infects the lungs and breathing passages. Although it can affect anyone, RSV is generally considered as the most frequent cause of lower respiratory tract infections in infants and young children. Each year about 125,000 infants are hospitalized with RSV in the United States. For more information on this infection, please visit:

RSV in Texas

RSV: The Texas Pediatric Society Infectious Diseases Committee is pleased to provide updated information on respiratory viral surveillance in children in our state. 

Per Texas DSHS RSV website “Individual cases of RSV are not reportable by law in Texas.RSV data are reported voluntarily by sentinel Texas laboratories on a weekly basis through the National Respiratory and Enteric Virus Surveillance System (NREVSS) sponsored by the Centers for Disease Control and Prevention (CDC). Sentinel providers report both the number of RSV tests performed and the number of positive tests detected on a weekly basis.”

RSV activity is shown by Texas DSHS as number of tests performed, number of tests positive, and the percent of tests positive at A line indicates a cutoff of 3% for the percent positive RSV PCR tests. The definition of the start of the RSV season is the first of 2 consecutive weeks with ≥3% positive RSV PCR tests.

Historically, this information was submitted by an increasing number of clinical microbiology labs that serve large numbers of children in different regions around the state. This began as a voluntary unfunded program with the Centers for Disease Control, Texas Department of State Health Services, and the Texas Pediatric Society with 8 labs representing larger pediatric centers around the state. It expanded with the addition of many more hospital laboratories with some support from MedImmune, via SDI. All of this data was combined at the CDC, in the NREVSS database. It was returned to Texas to clean up and present. The sites were grouped into regions and the data from those areas are combined. A list of the current sites and their grouping was provided. This was done for several years by Diana Newton and Dr. Don Murphey at Cook Children’s Medical Center in Fort Worth.

Elise Huebner, MS, CPH, CIC, currently serves as the acting RSV/Flu Surveillance Coordinator at Texas DSHS in Austin. The Texas RSV task force chaired by Dr. Manjusha Gaglani and includes some of the TPS Infectious Disease Committee members.
