A study of human parvovirus B19 infection in 1,967 pregnant women of all races in Johannesburg revealed an overall prevalence of 24.9% for IgG antibodies and 3.3% for IgM antibodies. Of the 64 IgM-positive sera indicating active infection, 62 were resistant to urea denaturation. No differences in the prevalence of IgG antibodies between population groups were observed, but active infections, as demonstrated by IgM antibodies, were significantly more prevalent in black than in white, coloured or Asian mothers.
一项针对约翰内斯堡1967名所有种族孕妇的人类细小病毒B19感染研究显示，IgG抗体的总体患病率为24.9%，IgM抗体的总体患病率为3.3%。在64份表明存在活动性感染的IgM阳性血清中，62份对尿素变性具有抗性。未观察到不同人群组之间IgG抗体患病率的差异，但如IgM抗体所示，活动性感染在黑人母亲中比在白人、混血或亚洲母亲中更为普遍。
