Simple colds and respiratory infections can often be self-diagnosed, meaning that most people find it quite obvious that they have developed a "cold." Many simple colds are associated with Rhino viruses that circulate around households and communities, especially in the wintertime. Such cold viruses often begin with an itching or burning sensation in the eyes, a sore throat and a vague malaise. Mucous congestion in the nose, sinuses, throat or chest may follow, providing a hospitable environment for bacteria. Thus, a typical progression is sore throat, followed by congestion, followed by secondary bacterial infections. Most people know their symptoms, can diagnose a "cold" themselves, and have their own favorite home remedies, from Echinacea and Vitamin C to a short fast, steam inhalation, garlic, ginger, honey or lemon in hot water.
