The duration of cold symptoms varies depending on individual constitution and the type of cold. Generally, a common cold may take three to five days to recover, while influenza could require five to ten days. The specific duration depends on the quantity of the virus and the body's immune capacity. Both influenza and the common cold are viral infections that cause illness, and there are some differences in symptoms. However, the treatment plans are the same, focusing on symptomatic treatment, complemented by antiviral medication, with recommendations to drink plenty of water, rest, and boost metabolism.
