Feeling sick can be confusing—especially when symptoms overlap between common illnesses like COVID-19, the flu, and strep throat. This downloadable symptom comparison guide helps you understand the key signs of each condition, what symptoms they share, and how they differ.

While symptom checklists are a helpful first step, they cannot replace a professional medical evaluation. Because COVID-19, influenza, and strep throat require different treatments, seeing a healthcare provider for proper testing and diagnosis is essential. Early evaluation can lead to the right care, faster recovery, and a reduced risk of complications or spreading illness to others.

Use this resource to stay informed about strep, flu, and COVID-19 symptoms—and if you or a loved one have symptoms, seek medical care from a qualified provider.
