Laboratory Results

The National Respiratory and Enteric Virus Surveillance System (NREVSS) collects information on a variety of respiratory viruses including influenza, parainfluenza, respiratory syncytial virus (RSV), rhinovirus, human metapneumovirus (HMPV), and respiratory adenovirus. The results from week 22 are summarized below.

U.S. Outpatient Influenza-like Illness Surveillance Network

Thirty-eight providers in Texas reported data to the U.S. Outpatient Influenza-like Illness Surveillance Network (ILINet) (formerly known as the U.S. Influenza Sentinel Provider Surveillance System) on patients with influenza-like illness (ILI) and total patients seen for any reason during week 22. Of the 38 providers who saw patients, 13 (34%) saw at least one patient with ILI. Of all patient visits during this week, 1.97% were due to ILI.
