Pathogenesis (development of disease)
The disease is caused by coxsackie viruses. The RNA virus belongs to the genus of enteroviruses, to the family of picornaviruses. Serotypes A and B can be distinguished, which in turn can be divided into several subgroups. Herpangina is caused by group A coxsackie virus. Type A4 is the most common pathogen, with A1 to A3, A5 to A10, and A16 to A22 and B3 less common.
The virus multiplies in the intestinal tract and then spreads via blood and the lymphatic system. A wide variety of organ systems may be involved.
