Flu Surveillance Data

Background

• The exact number of flu cases in Texas is unknown because most flu cases are not reportable, meaning that doctors, hospitals and others are not required to report them to public health authorities.
• To track and assess flu activity, DSHS relies on reports from a sentinel surveillance network of doctors, hospitals and others who have agreed to report flu cases.
• From those reports and other sources, DSHS prepares a Weekly Flu Surveillance Report. Part of that report classifies the flu activity level in Texas using classification criteria developed by CDC. The classifications range from no activity to sporadic, local, regional and widespread.
• The weekly report also includes laboratory test results showing what types and subtypes of flu are circulating in Texas, the estimated level of flu-like illnesses occurring and the number of pediatric flu-associated deaths.
