Flu activity remains high in North Texas.  Dallas County has reported five flu-related deaths this season. There have been two in Tarrant County.

With Texas and 45 other states reporting widespread flu activity, the Centers for Disease Control and Prevention (CDC) declared a flu epidemic. Part of the blame goes to the current flu vaccine. It's less effective against Influenza A or H3N2 - the more severe strain causing the majority of cases.

However, Dr. Glenn Hardesty says get the shot, if you haven’t already. The emergency room physician at Texas Health Arlington Memorial Hospital talked about the vaccine and the flu season in this edition of KERA’s consumer health series, Vital Signs.
