Cold & Flu
The common cold and seasonal flu are caused by viruses. They are indeed both respiratory illnesses and can cause similar symptoms. However, different viruses cause these two conditions, and your symptoms will gradually help you differentiate between the two. Use over-the-counter cold medications to relieve symptoms including sore throat, runny nose, congestion, and cough. Flu symptoms are similar but are more severe than cold symptoms and may include fever, headache and muscle soreness. See a doctor who may prescribe antiviral medications.
