Flu (Influenza)

Flu Season 2023-2024

Updated Sept. 6, 2023

Spokane Regional Health District (SRHD) anticipates a potentially active flu season for 2023-2024. In addition to flu, cases of COVID-19 and respiratory syncytial virus (RSV) are expected to increase as well. However, unlike last year, which saw a spike in RSV, COVID-19 and flu cases, we have more tools to help keep those most vulnerable safe with new vaccines and treatments for RSV, updated vaccines for COVID-19, and of course, this year’s flu vaccines. The best thing you can do to protect yourself and others and reduce the burden on health care systems is to get vaccinated before flu season begins!

About Influenza (Flu)

Influenza, commonly referred to as “the flu," is a highly contagious respiratory illness caused by a virus that infects the nose, throat and lungs. It can cause moderate to severe illness. It is not what people sometimes refer to as the “stomach flu” where there is primarily vomiting and diarrhea. That is a gastrointestinal virus, not respiratory.

Flu occurs in the United States most often in the fall and winter. In Spokane County, the virus commonly peaks in January through mid-March.

The flu spreads from person to person by coughing and sneezing and can spread to others before a person knows they're sick. Adults can infect others one day before symptoms develop and up to five days after becoming sick. Kids can spread the virus for 10 or more days.

  • Fever
  • Cough, which can be severe
  • Sore throat

  • Headache, which can be severe
  • Some people may have vomiting or diarrhea – this is more common in children than in adults

If you or someone you know has these symptoms and they are severe, contact your doctor, nurse or clinic as soon as possible. The best way to tell if you have flu is for a healthcare provider to swab your throat and have a lab confirm the diagnosis.
