Flu Season

Influenza, or the “flu”, easily spreads person to person. The flu is caused by influenza viruses, which attacks the nose, throat, and lungs. The COVID-19 pandemic has made it highly important to reducing the spread of respiratory illnesses, like the flu, this fall and winter.

The Centers for Disease Control and Prevention (CDC) recommends a yearly flu vaccine for everyone 6 months of age and older, and is the most important step in protecting against this serious disease.  Receiving the flu vaccine is particularly important for people who are at high risk of serious complications from influenza.

Signs & Symptoms of the Flu

The flu can cause mild to severe illness, and at times can lead to death. The flu is different from a cold and can come on suddenly. Symptoms of the flu include:

  • Fever* or feeling feverish/chills
  • Cough
  • Sore throat
  • Runny or stuffy nose
  • Muscle or body aches
  • Headaches
  • Fatigue (tiredness)
  • Some people may have vomiting and diarrhea, though this is more common in children than adults.

*It’s important to note that not everyone with flu will have a fever.

How Flu Spreads

Most experts believe that the flu viruses spread mainly by tiny droplets made when people with the virus cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby. Less often, a person might get the flu by touching a surface or object that has flu virus on it and then touching their own mouth, nose or possibly their eyes.

High Risk for Developing Flu-Related Complications

The below health and age factors are known to increase a person's risk of getting serious complications from flu:

  • Children younger than five, but especially children younger than two years old
  • Adults 65 years of age and older
  • Pregnant women
  • Residents of nursing homes and other long-term care facilities
  • People who have pre-existing medical conditions such as asthma, heart disease, and diabetes
