The cold is the most common infectious disease in the United States and unfortunately it becomes prevalent during the holiday season. In the United States it is estimated that the average adult will get a cold typically two times a year, while children may have up to ten. The typical cold accounts for more missed work and absences at school than any other illness. People typically see their primary care physician for colds, however it is a viral infection and all doctors can do is say to get plenty of rest and drink plenty of fluids. Treating colds with antibiotics are virtually useless because antibiotics treat bacterial infections and a cold is a viral infection.
