Clinical Characteristics of Human Parvovirus B19 Infection in Children

Abstract

Purpose: Human parvovirus B19 infection is widespread and has a heterogeneous clinical spectrum, ranging from asymptomatic infection to potentially life-threatening complications. We investigated the various clinical features of human parvovirus B19 infection during an outbreak of the virus in our community. Methods: A retrospective chart review study was conducted at the Pusan National University Children's Hospital from December 2017 to April 2019. We investigated the clinical features of children with parvovirus B19 immunoglobulin M or parvovirus B19 DNA detected using polymerase chain reaction. Results: A total of 24 children were diagnosed with parvovirus B19 infection. Twelve (50%) had lace form rashes, and four (16.7%) had petechial rashes. Two (8.3%) were diagnosed with fever without a focus. Six (25%) developed aplastic crisis as a complication of infection, of whom three were previously diagnosed with hereditary spherocytosis and three with acute lymphoblastic leukemia. Conclusions: In addition to erythema infectiosum, the parvovirus B19 infection can present clinically with various types of rashes and fever without a focus. Furthermore, hematologic manifestations such as neutropenia and aplastic crisis can occur during infection.

“…Детям с ТАК показаны экстренные повторные трансфузии эритромассы [41]. Больным с хронической парвовирусной инфекцией и анемией наряду с трансфузией эритроцитов вводят внутривенный иммуноглобулин человека в дозе 0,4 г/кг в течение 5 дней или 1 г/ кг 3 дня, что способствует повышению количества ретикулоцитов, концентрации гемоглобина и элиминации вируса из организма.…”
