Pharyngitis associated with a common cold is usually caused by the typical respiratory viruses (influenza, parainfluenza or adenoviruses). However, rare causes of the disease may also be other viruses such as herpes simplex, coxsackie or echoviruses. In addition, viruses that sometimes cause systemic diseases, such as Epstein-Barr, cytomegalovirus, measles or rubella viruses may also be the pathogen involved in pharyngitis.
Bacteria are less likely to cause pharyngitis. β-hemolytic streptococci may be involved and additional symptoms such as fever, malaise and headache occur. The throat and palate and the regional lymph nodes are red, swollen and tender.
