Viral Sore Throat. More than half of all sore throats are caused by viruses (known medically as viral pharyngitis). They are often the same viruses that cause the common cold, flu, a sinus infection (sinusitis), or other upper respiratory tract infections. Rhinovirus infections appear to be the most common reason for a sore throat.
Not all sore throats are a result of a strep infection. Other illnesses can cause this symptom, too. These include the common cold, a sinus infection, post-nasal drip, and acid reflux. Sore throats caused by other medical conditions usually improve on their own with or without treatment in a few days.
