Virus exanthema (overview)B09
Synonym(s)
viral exanthema; Virus exanthema
DefinitionThis section has been translated automatically.
Generalized rashes of different clinical symptoms and morphology induced directly (infectious exanthema) or indirectly (parainfectious exanthema) by viruses. The clinic of infectious viral exanthema is the expression of a defined pathogen (e.g. varicella, measles, etc.). The clinic of parainfectious viral exanthema (e.g. Gianotti-Crosti syndrome; unilateral laterothoracic exanthema; postherpetic erythema exsudativum multiforme) can be caused by different pathogens. The clinical manifestations are very different. They can generally be triggered by different pathogens. For example, in Gianotti-Crosti syndrome 13 different types of viruses are known.
PathogenThis section has been translated automatically.
The most common causative agents of viral exanthems are:
- Adenoviruses (rubeoliform exanthema).
- Coxsackie A viruses ( herpangina; hand-foot-and-mouth disease; generalized vesicular exanthema; AGEP)
- ECHO viruses (maculo-papular exanthema, erythema infectiosum-like exanthema)
- Epstein-Barr viruses ( infectious mononucleosis, unilateral laterothoracic syndrome?)
- Hepatitis B and hepatitis C viruses (non-specific exanthema, Gianotti-Crosti syndrome; glove-sock syndrome)
- HHV-6 viruses ( exanthema subitum)
- HHV-7 viruses ( exanthema subitum, pityriasis rosea?)
- Herpes simplex viruses
- HIV/AIDS
- Measles viruses
- Mumps virus (maculo-papular exanthema)
- Parainfluenza viruses (non-specific exanthema; Gianotti-Crosti syndrome)
- Parvoviruses [parvovirus B19] ( erythema infectiosum = ringworm; glove-sock syndrome)
- Rubella
- Rotaviruses (maculo-papular exanthema)
- Corona viruses: urticarial, morbilliform, varicelliform exanthema, pseudofrost bumps in COVID-19 infections.
- RS viruses ( respiratory syncytial virus diseases; nonspecific exanthema).
- Varicella zoster ( varicella, zoster).

Therapy is usually symptomatic and, if necessary, with antivirals.
