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.
A sore throat (pharyngitis) is a common problem and usually is caused by a viral or bacterial infection. Sore throat usually resolves on its own without complications in adults, although it is important to know when to seek medical attention. Viruses can cause a sore throat and other upper respiratory infections, such as the common cold. Sore throat caused by a virus is not treated with antibiotics but instead may be treated with rest, pain medication, and other therapies aimed at relieving symptoms.
