Clinical featuresThis section has been translated automatically.
- General: Incubation period: 2-24 days. Followed by fever for 2-4 days, headache, muscle pain, sweating, chills, cough, lymphadenopathy.
- Integument: Usually 2-10 acutely occurring papular and/or vesiculopustular skin lesions, mainly localized on the extremities. At first a small red macula becomes visible, which becomes increasingly raised in the centre and changes into plaque. The centre of the papule/plaque becomes necrotic. Approximately 1 week after the initial macula becomes visible, the plaque is about 10-15 mm in size. An environmental erythema and environmental oedema are visible. With increasing duration, the plaques decay and begin to ulcerate (usually stimulated by scratching artifacts) or increase in firmness and consistency until red nodes measuring approx. 20 mm in diameter have developed. Scarred spontaneous healing of the nodules over 6-8 weeks with formation of typical "pockmarks". Secondary impetiginisation is common with ulceration.
TherapyThis section has been translated automatically.
Symptomatic. Treatment of pruritus, if necessary. Possibly antibiotic therapy of secondary infections.
