Many different microorganisms can produce pharyngitis, a problem with the tonsils or pharynx. The exact source of the infection can be diverse, but it can usually be found in the pharynx and upper respiratory tract. This condition is usually produced during conditions such as some influenza syndromes and common cold. There are several culprits for the production of this condition, so we will discuss some of them.


The condition called pharyngoconjucival fever and pharyngitis problems without any complications, are produced by adenovirus, the virus that attacks the pharyngeal mucosa directly. Several problems are caused by this condition and some of them include sore throat, fever and conjunctivitis. Problems connected with this virus, are usually found in children.

Herpes simplex virus

This virus causes gingivitis, pharyngitis and stomatitis. When this virus enters human body, it starts to multiple and infect autonomic or sensory nerve endings. This condition then starts to spread, and produce problems, like lesions, far away from the original place of the problem.


One of the most blamed viruses for the production of pharyngitis is rhinovirus. This virus produces hyperemia and edema in the nasal mucous membranes, thus leading to problems like mucous membrane swelling, nasal passages narrowing and several others. This condition creates lysyl-bradykinin and bradykinin in the nasal passage and because of this, pain is felt by the nerve endings.

Epstein-Barr virus

This virus is mostly seen in mononucleosis infections, and is transferred form saliva, usually from an adult to a child. Problems that include hyperemia and edema of the pharyngeal mucosa and tonsils, nasopharyngeal lymphoid hyperplasia and inflammatory exudates are connected with this virus.


Coxsackievirus and echovirus are the most blamed enteroviruses for the creation of pahryngitis. These viruses can be transferred by air and are usually a result of a secondary infection.

Parainfluenza virus

There are three types of this virus, and the third type can occur both, sporadically and epidemically, while type 1 can manifest sporadically, and type 2 manifests epidemically.

Human immunodeficiency virus

This virus is the first sign of HIV, and when we talk about the frequency of this condition, we can say that it is very common, since more than 40 million people suffer from this condition. This condition is not very choosy and it affects both genres and all races equally, though it seems to prefer children.

There are several complications from pharyngitis possible. Some of them are necrotic apiglottitis, splenic rupture, pneumonia, encephalitis, pericarditis, and several others.
