What is true about the common cold as a health concern?

The common cold is indeed usually mild and self-limiting, making this statement accurate. Most colds are caused by viruses, primarily rhinoviruses, and the body's immune system typically handles these infections effectively without the need for medical intervention. Symptoms, which may include a runny nose, cough, and sore throat, usually resolve on their own within a week or two.

This characteristic of being self-limiting is important because it indicates that most individuals can recover at home with adequate rest and hydration, rather than seeking medical treatment. Understanding this can help inform decisions about when to seek help and alleviate unnecessary anxiety over the illness.
