Human herpesvirus 7: Another causal agent for roseola (exanthem subitum)

Abstract Human herpesvirus 7 (HHV-7) was isolated from peripheral blood mononuclear cells of two infants with typical exanthem subitum. The Hin dIII-, Bam HI-, and Eco RI-digested DNA patterns of the isolated viruses were very similar to that of the prototype HHV-7 (RK strain), but different from that of human herpesvirus 6 (HHV-6). During the convalescent period of the first patient, the titer of antibody to HHV-7 rose from EDIATR 1994;125:1-5)
