Only one person was reported hospitalized last week because of the flu, according to the state Health Department.
Since Sept. 30, seven Oklahoma residents have been hospitalized because of influenza, a contagious respiratory illness. The state Health Department has not reported any flu-related deaths this season.
The bulk of hospitalizations this year has been among people older than 65.
Young children, adults older than 65, pregnant women and adults with chronic health conditions, such as asthma or diabetes, are most at risk of developing serious complications related to the flu, according to the state Health Department.
Health department officials also recommend parents and people around young children get their flu shot.
Anyone older than 6 months is encouraged to get a flu vaccine. Doctors' offices, county health departments and some pharmacies offer the flu vaccine, and some offer the vaccine through a nasal mist, similar to nasal spray.
A high-dose flu vaccination is available for people older than 65 to offer extra protection. Also, some clinics have an intradermal flu shot that uses a smaller needle.
During Oklahoma's last flu season, which ran from October until about May, Oklahoma saw its number of cases peak in late February and early March.
