The common cold is a viral infectious disease that spreads easily. Symptoms include sore throat and nasal congestion. There is no cure, and one must wait for it to run its course. The average person gets 2-3 colds per year. While not life-threatening, the cold can be a nuisance by making it difficult to focus on tasks and causing people to avoid those infected. A cure for the common cold would help make dealing with life's troubles more bearable.
