While reports of influenza-like illness have decreased, influenza activity is still high across the state and is above the Texas-specific ILI baseline. Compared to the previous week, the percentage of specimens testing positive for influenza reported by hospital laboratories has decreased. The percentage of patient visits due to influenza-like illness (ILI) has decreased. One influenza-associated pediatric death was reported.
