The percentage of specimens testing positive for influenza reported by public health laboratories marginally decreased. No influenza-associated pediatric deaths were reported. No influenza-associated outbreaks were reported. In addition to flu, other respiratory viruses—especially rhinovirus/enterovirus—were detected in Texas during week 37.
