Flu and the common cold are both respiratory illnesses, but they are caused by different viruses. Due to the similarities between the symptoms of the two, it can be difficult to tell the difference between them based on symptoms alone. In general, flu is worse than the common cold, and symptoms are more intense. The flu symptoms will start more abruptly and will last longer than the common cold. Having a cold can last 2-3 days when the flu can last up to a week. The flu is much more dangerous because it can lead to other serious complications. Not to fear, most flu cases are not fatal but can be if not taken care of properly. Do your best on preventing the spread, especially during these times, due to the prolific nature of COVID.
