Flu Q & A

What is the flu?

The flu, an illness caused by viruses in the influenza family, primarily affects your respiratory system. The symptoms range from mild in some cases to severe in others, and without adequate management, severe cases can be deadly. 

Like the common cold and other viral respiratory illnesses, the flu is contagious and tends to spread through water droplets in the air. Any time you cough, sneeze, or talk, the particles are projected into the air around you and can land in someone else’s mouth or nose. 

How can I tell if I have the flu?

Flu symptoms and cold symptoms share many similarities, but there are a few key differences that can help your physician at Redwood Family Health Center make the right diagnosis. Flu symptoms tend to include:

  • Aches and pains
  • Chills
  • Weakness and fatigue
  • Coughing
  • Sore throat
  • Congestion and runny nose
  • Headaches
  • Fever


The common cold rarely causes a fever; fevers are much more common with the flu. Another key difference is that flu symptoms tend to set in abruptly and are more severe than cold symptoms, which have a more gradual onset. You can expect symptoms to set in about 1-4 days after exposure. 

How can I prevent the flu?

The flu is most active and transmissible during “flu season,” which extends from fall until spring. To significantly lower your risk of getting the flu, you should get the seasonal flu vaccine every fall. 

The flu vaccine changes every year based on the strains of the influenza virus that are projected to be the most active and widespread through rigorous research. The most common way to get the vaccine is via an injection in your arm, but nasal spray options may be available too. 

How is the flu treated?

Treating the flu is possible, and there are lots of different remedies for the symptoms. Once your physician confirms a flu diagnosis, often with a swab test, they can prescribe antiviral medications to relieve the infection if you’re a candidate for these drugs. These medications are available in several forms, including pills and liquids. 

For some quick relief from flu symptoms, you can use:

  • Over-the-counter pain relievers
  • Rest
  • Adequate fluid intake
  • Humidifiers


You should also stay home from work, school, and social activities while recovering from the flu, so you don’t spread the illness to those around you.

If you have symptoms like a stuffy nose and fever, and you suspect they might indicate the flu, call Redwood Family Health Center for a sick visit or request an appointment online today.
