Often lumped together because they have similar symptoms, colds and the flu have several differences. "In general, the flu comes on suddenly and symptoms are more severe, especially body aches. Colds tend to begin with one or two symptoms—most often a sore throat—then gradual onset of nasal congestion and cough," says Matt Nimer, a physician assistant specializing in family medicine at University of Utah Health.
