The common cold is a viral infection that can last for 7 to 10 days on average, although symptoms may persist for up to two weeks in some cases. However, some symptoms, such as a cough or a runny nose, may last for a few weeks even after the initial infection has resolved. It’s important to rest, drink fluids, and manage your symptoms with over-the-counter medications to help your body fight the infection and feel more comfortable. If your symptoms persist or worsen, it’s always a good idea to check with your healthcare provider to rule out any complications.
