Flu Surveillance — January 13, 2009

DSHS’s latest flu report, for the week ending Jan. 10, classifies flu activity in Texas as “local.”

The “local” classification is used when there are increases in laboratory-confirmed flu and flu-like illnesses in one region in the state during the week.

DSHS reported “widespread” for the same week last year.

DSHS has confirmed one flu-associated pediatric death in Texas this season.

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.

This Flu Surveillance item is updated weekly on Tuesday.
