Flu season in Oklahoma continues at a steady pace.
Between Oct. 7 and Oct. 20, two Oklahomans were hospitalized with the flu, according to the state Health Department.
Since flu season began Sept. 30, the state Health Department has reported six cases of flu-related hospitalizations. No flu-related deaths have been reported this season in Oklahoma.
Influenza is a contagious respiratory illness caused by one of two types of viruses, according to the Centers for Disease Control and Prevention. Symptoms include fever, cough, sore throat, headache and fatigue. Young children and older adults are at greatest risk for developing serious complications.
Anyone at least 6 months old is encouraged to get a flu shot. Local health departments, physician's offices and some pharmacies have vaccine available to provide flu shots. There are discount and voucher programs in place for people who are uninsured or underinsured, and cannot afford to pay full price.
This season's flu vaccine will protect against the three influenza viruses that research indicates will be most common, according to the CDC. Included are an influenza A (H1N1) virus, an influenza A (H3N2) virus and an influenza B virus.
