The "Common" Cold

A cold is a viral infection, and symptoms include coughing, runny nose, sore throat, sneezing, fatigue, headache, and fever.  These symptoms usually resolve in 7 to 10 days, but can last as long as six weeks.  There are over 200 strains of viruses that can cause a cold, most of them rhinoviruses.  Unfortunately, scientists continue to discover new viruses that can cause a cold.

Colds are most contagious about two days before symptoms start and in the early stages of a cold.  Transmission is usually by airborne droplets, direct contact with infected nasal secretions, or contact with contaminated objects.  Adults usually get two to five colds a year, whereas children can get as many as seven to ten colds.  These colds usually occur between September and May.

There is no cure for the common cold, but symptomatic treatment may help reduce symptom severity.  Hand washing and wearing a mask are considered good prevention measures.  Stress reduction, exercise, and adequate sleep can also help prevent getting a cold.
