Pharyngitis is a type of upper respiratory tract infection. [7] Most cases are caused by a viral infection. [2] Strep throat, a bacterial infection, is the cause in about 25% of children and 10% of adults. [2] Uncommon causes include other bacteria such as gonococcus, fungi, irritants such as smoke, allergies, and gastroesophageal reflux disease.
An upper respiratory tract infection (URTI) is an illness caused by an acute infection, which involves the upper respiratory tract, including the nose, sinuses, pharynx, larynx or trachea. [3] [4] This commonly includes nasal obstruction, sore throat, tonsillitis, pharyngitis, laryngitis, sinusitis, otitis media, and the common cold.
A 2015 study of young adult students presenting to a single clinic in Alabama had F. necrophorum as the predominant causative organism for pharyngitis 21% of the time (and found in 9% of asymptomatic students). [11] In the same study, Group A Streptococcus was found in 10% of pharyngitis patients (1% of asymptomatic students).
[1] [5] [6] When caused by the bacterium group A streptococcus, it is classed as streptococcal tonsillitis [11] also referred to as strep throat. [12] Rarely bacteria such as Neisseria gonorrhoeae, Corynebacterium diphtheriae, or Haemophilus influenzae may be the cause. [5] Typically the infection is spread between people through the air. [6]
Lemierre's syndrome begins with an infection of the head and neck region, with most primary sources of infection in the palatine tonsils and peritonsillar tissue. [10] Usually this infection is a pharyngitis (which occurred in 87.1% of patients as reported by a literature review [6]), and can be preceded by infectious mononucleosis as reported ...
Orbital cellulitis is inflammation of eye tissues behind the orbital septum. It is most commonly caused by an acute spread of infection into the eye socket from either the adjacent sinuses or through the blood. It may also occur after trauma. When it affects the rear of the eye, it is known as retro-orbital cellulitis.
