Flu Season

The flu is a viral respiratory illness most common during the fall and winter months but has no set schedule. Each year brings different cycles and it is not possible to predict the severity of the flu before the season starts.


The most common symptoms include fever, cough, sore throat, runny nose, muscle or body aches and fatigue. Always check with a doctor if you think you are experiencing symptoms of the flu.


Antiviral medications prescribed by a doctor may be used as a treatment option. Antiviral medications can help with symptoms and shorten the amount of time you are sick. The CDC recommends prompt treatment for those who suspect they have the flu.

Chickasaw Nation Public Health Nursing Flu Vaccines

Public Health is an important component to have within our surrounding communities. Its mission is providing quality care for all and raising the awareness of overall health. Public Health Nursing provides flu vaccines and other immunization opportunities to the public.

The colder temperatures encourage the spread of respiratory viruses such as the flu and COVID-19. The recently authorized bivalent COVID-19 booster from Pfizer is recommended for individuals ages 12 and older at least two months after the completion of the initial vaccine series or the most recent booster. The CNDH exclusively offers the Pfizer vaccine in all clinics.

The bivalent booster can be given safely at the same time as the flu shot. Both vaccines are available to all First Americans by appointment in primary care clinics at Chickasaw Nation Medical Center and satellite clinics in Ardmore, Purcell and Tishomingo.
