Influenza is a contagious viral illness that peaks in January and February.
Weekly state Health Department data released Wednesday lists influenza and flu-like illness activity as sporadic, with no outbreaks occurring in the state.
Eighteen counties in northwestern Oklahoma are reporting elevated numbers of influenza-like illnesses.
