A typical clinical picture of parvovirus B 19 infection cannot be always well distinguished from other exanthematous diseases. Differential diagnosis includes skin presentation of allergy, parainfection exanthem during several viral and bacterial infections, vaccination against exanthematous disease failure and atypical presentation of exanthematous disease in vaccinated patients. Viral etiology cannot be confirmed without laboratory identification. Good interpretation of the results of serological tests requires good knowledge of the topic and cooperation of clinically, microbiologically and epidemiologically educated members of the medical staff.
