How to Tell the Difference Between a Cold, Flu, And Allergies
Understanding The Main Differences: Many people confuse colds, the flu, and allergies because they can share similar symptoms. A runny nose, sneezing, and coughing may happen with all three. However, each condition has different causes and warning signs. Knowing the difference can help you choose the right treatment and decide if you should see a doctor. A cold and the flu are caused by viruses. Allergies are caused by the immune system reacting to things like pollen, dust, pet dander, or mold. The way symptoms appear and how long they last can help you tell them apart.
