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. Public health authorities do not require providers report flu cases so we do not know exact flu numbers.

From the sentinel surveillance network and other sources, we prepare a Weekly Flu Surveillance Report. We use a classification criteria developed by CDC to classify flu activity in Texas.

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.
