Cold vs. strep: Dr. Joshua Tepper explains how to tell the difference

A sore throat may be a symptom of the common cold or it could be something more serious.

Dr. Joshua Tepper, family physician and an associate professor at the University of Toronto, explains the difference between a cold and getting strep throat.

While strep can be easily treated, he said there are times it can be a bigger problem and in same cases, even fatal.

"It can affect your heart, your joints, your kidneys," he said. "It can cause something life-threatening called toxic shock syndrome."
