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.
Fortunately, most sore throats are caused by a minor illness and go away without medical treatment. Several conditions can cause a sore throat. Sore throats may be caused by a viral illness, such as: 1  The common cold, the most common type of viral infection. 2  Infection of the voice box (laryngitis).3  Mononucleosis (mono, the kissing disease), a viral infection that tends to cause a persistent sore throat. bacterial infection may also cause a sore throat. This can occur from: 1  Strep throat, which usually does not occur with congestion or a cough. 2  An inflammation or infection of the tonsils (tonsillitis) and sometimes the adenoids (adenoiditis). 3  An infection of the tissues around the tonsils (peritonsillar abscess).
