DefinitionThis section has been translated automatically.
Worldwide occurring exanthematic infectious disease caused by Coxsackie A 6 and more rarely Coxsackie A 10.
PathogenThis section has been translated automatically.
The pathogens are not Coxsackie A 16 and Enterovirus 71 as in the classic hand-foot-and-mouth disease, but Coxsackie A6 virus and, more rarely, Coxsackie A10 virus. The transmission of the virus is faeco-oral.

ManifestationThis section has been translated automatically.
In contrast to the typical age distribution of enterovirus infections, individual outbreaks often also affected adults (e.g. 25% in the USA). A hand-foot-mouth disease in adults is rather rare due to the high infestation in childhood! If adults are affected, this may indicate an immunological naivety of these adults towards the currently circulating Coxsackie-A6 virus strain.
LocalizationThis section has been translated automatically.
face, extremities, trunk buttocks
Clinical featuresThis section has been translated automatically.
Polymorphic exanthema with papules, vesicles, blisters and erosions. After 3 weeks the appearance of onycholysis is characteristic. In individual outbreaks there was a severe clinical expression of the symptoms with perioral and perianal vesicles, high fever and subsequent onycholysis. Multiple intrafamily virus transmissions from children to parents have also been detected.
DiagnosisThis section has been translated automatically.
From smears from vesicles or erosions detection of the pathogen by RT-PCR on Coxsackie-A6.
Further diagnostics for molecular typing includes PCR in the protein-coding VP1 region with subsequent sequencing (reference laboratory). Stool samples, throat swabs and vesicle contents are best suited for the detection of enteroviruses. In case of CNS manifestation, CSF can also be examined. Approximately 80 % of the pathogens can be detected from the stool in the first 1-2 weeks of the disease.

Symptomatic
ProphylaxisThis section has been translated automatically.
The risk of infection can be reduced by good hand hygiene:
- Regular and careful hand washing with soap, especially after nappies and after going to the toilet, plays a crucial role.
- Dirty surfaces and objects (including toys and door handles) must be cleaned particularly thoroughly in accordance with the hygiene plan of public institutions.
- Close contact with sick people should be avoided (kissing, hugging, sharing cutlery or cups etc.).
Note(s)This section has been translated automatically.
The serotype Coxsackievirus A6 is primarily associated with the clinical picture of herpangina. It has been associated with outbreaks of hand-foot-and-mouth disease in Finland in 2008, France and Taiwan in 2010, Japan in 2011, USA in 2012.
Since the Hand-Foot-Mouth Disease is not subject to notification according to the German Protection against Infection Act (IfSG) and virological diagnostics are not usually performed, there are no valid epidemiological data on Hand-Foot-Mouth Disease in Germany.
