Think you aren't contagious? Think again.

Ever sat next to someone coughing and sneezing who insists they’re “not contagious”? In this episode of Healthy Looks Great on You, Dr. Vickie takes listeners to mini medical school to explain how contagious respiratory illnesses actually spread.

From the common cold to influenza, RSV, and COVID-19, many upper respiratory infections are contagious before you even realize you’re sick. Dr. Vickie explains the signs that suggest you may be spreading germs, how long common viruses remain contagious, and why symptoms like coughing and sneezing matter—even if you don’t have a fever.

You’ll also learn the difference between viral and bacterial infections, why leftover antibiotics are a bad idea, and how new strategies are helping protect babies and older adults from RSV.

Along the way, Dr. Vickie shares a few humorous real-life moments—from wiping down grocery carts to a surprising produce-aisle hygiene lesson.

If you’ve ever wondered whether you should stay home when you’re sick, this episode will help you understand when you might be contagious—and how simple habits can help protect the people around you.
