Flu Surveillance — October 20, 2009
DSHS’s latest flu report, for the week ending Oct. 17, classifies flu activity in Texas as “widespread.”
The “widespread” classification is used when there are increases in flu-like illnesses and recent lab-confirmed flu cases in at least half of the state's regions.
Flu is not a reportable condition in Texas, but DSHS relies on reports from a surveillance network to classify flu activity. DSHS reports the weekly classifications to the CDC.
CDC’s flu-activity classifications range from no activity to sporadic, local, regional and widespread.
