Fall is approaching which means flu season is also. During the COVID-19 pandemic, you may have heard that the coronavirus is similar to the flu.2 Both are contagious respiratory illnesses, but there are some key differences between the two.3

Similarities Between COVID-19 and the Flu

For both COVID-19 and the flu, one or more days can pass between when a person becomes infected and when he or she starts to experience symptoms.1 Both of these viruses can spread in similar ways. They spread through respiratory droplets or aerosols released while talking, sneezing, or walking.2 COVID-19 and the flu have many signs and symptoms including:2

  1. Fever

  2. Cough

  3. Shortness of breath

  4. Fatigue

  5. Sore throat

  6. Headache

  7. Muscle pain or body ached

The signs and symptoms for these viruses can range from no symptoms to mild or severe.2 COVID-19 and the flu can lead to serious complications such as pneumonia, organ failure, heart attacks or stroke.2

Differences Between COVID-19 and the Flu

A few key differences between COVID-19 and the flu are:

  1. While with COVID-19, you may experience symptoms two to 14 days after exposure, flu symptoms normally appear about one to four days after exposure.2

  2. Severe illnesses are more frequent with COVID-19.2

  3. A person with COVID-19 is contagious for a longer time than if they had the flu.1

  4. COVID-19 is generally more contagious than flu viruses.1

  5. COVID-19 illnesses resulting in hospitalization and death can occur even in healthy people.1
