HANOVER, VA (WWBT) - Dr. Aisha Aslam is on top of the strep throat threat.
She warns that most people with strep infection are contagious until they have been on an antibiotic for 24-48 hours.
Most sore throats are caused by viruses. Antibiotics should only be used if your strep test is positive.
See your doctor if you are exposed to sore throat and develop symptoms.
