question: Hello doctor, My 5 years old son got sick 2 and a half weeks ago. For 1 week he had high fever (up to 39 degrees Celsius) which we reduced with fever reducing syrup (Noraphen). Blood test showed that there is a chance for parvovirus (borderline result).  After a week the fever stopped, and for a week everything was fine (except our son feeling weak). After that symptoms of allergy and red stains on his arms and legs appeared, which matched the definition of parvovirus indeed, as his treating physician confirmed. These symptoms disappeared after 2 days, but now his fever is back to 38.1 degrees Celsius, which worries us. Let me sum it up: 1-7 days - fever up to 39 degrees Celsius which reduced by Noraphen. 8-14 days - no fever. 15-16 days - allergic response. 17th day - fever is back. I have attached the entire report. Kindly advice.
