*[[Streptococcus pyogenes]] (group A strep) is responsible for scarlet fever. It can also cause simple angina, erysipelas and serious toxin-mediated syndromes like [[necrotizing fasciitis]] and the so-called streptococal toxic shock-like syndrome. The virulence of group A strep seems to be increasing lately. The exanthem of scarlatina is thought to be due to erythrogenic toxin production by specific streptococcal strains in a nonimmune patient. Along with erythrogenic toxins, the Group A strep produces several toxins and enzymes. Two of the most important are the streptolysins O and S. Streptolysin O, an hemolytic, thermolabile and immunogenic toxin, is the base of an assay for scarlatina and erysipelas - the [[anti-streptolysin O titer]]. | |||

*The '''Epstein-Barr Virus''' ('''EBV'''), also called ''Human herpesvirus 4'' (HHV-4), is a [[virus]] of the [[herpesviridae|herpes family]] (which includes ''[[Herpes simplex virus]]'' and ''[[Cytomegalovirus]]''), and is one of the most common viruses in [[human]]s. Most people become infected with EBV, which is often [[asymptomatic]] but commonly causes [[infectious mononucleosis]]. | |||

*[[EBV|Epstein-Barr virus]] is ubiquitous across the globe and the strongest causative agent for the manifestation of [[infectious mononucleosis]]. Commonly, a person is first exposed to the virus during or after adolescence. Though once deemed "The Kissing Disease", recent research has shown that transmission of mononucleosis not only occurs from intimate contact with infected saliva, but also from contact with the airborne virus. | |||
*Symptoms of infectious mononucleosis are: | |||
:*[[fever]] | |||
:*[[sore throat]] | |||
:*[[Lymphadenopathy|swollen lymph glands]]. | |||
*Sometimes, a [[splenomegaly]] or [[hepatomegaly]] may develop. Heart problems or involvement of the central nervous system occurs only rarely, and [[infectious mononucleosis]] is almost never fatal. There are no known associations between active EBV infection and problems during pregnancy, such as miscarriages or birth defects. Although the symptoms of [[infectious mononucleosis]] usually resolve in 1 or 2 months, [[EBV]] remains dormant or latent in a few cells in the throat and blood for the rest of the person's life. Periodically, the virus can reactivate and is commonly found in the saliva of infected persons. This reactivation usually occurs without symptoms of illness. | |||

Overview
Differential Diagnosis
- There are two diseases that are distinguished to present similarly to Tonsillitis; they are Scarlet fever and Epstein Barr Virus.
| Disease | Definition |
|---|---|
| Scarlet Fever |
Rash
|
| Epstein-Barr Virus |
EBV is named after Michael Epstein and Yvonne Barr, who together with Bert Achong, discovered the virus in 1964.[3]

Differentiating between Common Misdiagnosis
Scarlet Fever
- Scarlet fever may be ruled out in testing for specific bacteria that produce the erythrogenic toxin.
- This toxin is ultimately the underlying cause of Scarlet fever.
- In its absence, Scarlet fever would only present as purulent tonsillitis.
Epstein-Barr
- Differentiated based on clinical manifestations.
- May be responsible for prolonged fatigue.
- Tonsillectomy may lead to further complications including an increased risk of hemorrhaging.
