HUANG Gaosheng
Abstract：In 1975,human parvovirus B19(B19V),which is only pathogenic to humans,was first discovered,but research has found that it existed for thousands of years.Due to the time limit of literature,B19V outbreak was recorded only in a unit or country.As for the harm of B19V to humans,it is generally believed that it is mostly mild,and typical manifestations and characteristic diseases are often introduced.However,their atypical manifestations,disability and mortality are not well understood.Since the beginning of 2024,sudden outbreaks of B19V infection have been reported in the United States and more than ten countries in Europe.The affected populations are mainly children and pregnant women,with child deaths and fetal loss posing significant risks.For atypical cases,diagnosis is often delayed due to difficulty in identifying B19V infection.This article briefly introduces the characteristics of B19V,the complexity and atypia of its manifestations,diagnostic criteria,the key problems of both outbreak period and long-term response strategies,providing suggestions for China to deal with the outbreak and final resolution of B19V infection.
