Usually, herpangina is produced by one particular strain of coxsackie virus A (and the term "herpangina virus" refers to coxsackievirus A), [1] but it can also be caused by coxsackievirus B or echoviruses. [2] Most cases of herpangina occur in the summer, [3] affecting mostly children. However, it occasionally occurs in adolescents and adults.
Hand, foot and mouth disease most commonly occurs in children under the age of 10 [4] [19] and more often under the age of 5, but it can also affect adults with varying symptoms. [20] It tends to occur in outbreaks during the spring, summer, and autumn seasons. [6] This is believed to be due to heat and humidity improving spread. [22]
Herpetic gingivostomatitis is an infection caused by the herpes simplex virus (HSV). The HSV is a double-stranded DNA virus categorised into two types; HSV-1 and HSV-2.HSV-1 is predominantly responsible for oral, facial and ocular infections whereas HSV-2 is responsible for most genital and cutaneous lower herpetic lesions.
Coxsackie A virus is a subgroup of enterovirus A, which are small, non-enveloped, positive-sense, single-stranded RNA viruses. Its protective, icosahedral capsid has an external portion that contains sixty copies of viral proteins (VP1,-2,-3) and an internal portion surrounding the RNA genome containing sixty copies of VP4 viral proteins.
In general, group A coxsackieviruses tend to infect the skin and mucous membranes, causing herpangina; acute hemorrhagic conjunctivitis; and hand, foot, and mouth disease. [2] Both group A and group B coxsackieviruses can cause nonspecific febrile illnesses, rashes, upper respiratory tract disease, and aseptic meningitis.
Herpangina is caused by Coxsackie A virus, and causes a vesicular rash in the oral cavity and on the pharynx, along with high fever, sore throat, malaise, and often dysphagia, loss of appetite, back pain, and headache. It is also self-limiting, with symptoms typically ending in 3–4 days.

Common symptoms can include myocarditis, meningoencephalitis, and hepatitis. Other less severe symptoms can include pneumonia, Gastrointestinal symptoms, pancreatitis, and seizures. Patients with Coxsackie B4 virus have seemed to have herpangina, tonsillitis, and pharyngitis. [6] CB4 virus has caused transplacental infections in mice.
