^aTwo infants had congenital CMV infection. These households were excluded from analyses of CMV.
^bNine primary HSV infections were type 1 (8 from infants and 1 from a secondary child) and one was type 2 (infant).
^cThree primary EBV infections were identified among secondary children.
^dPercentage of positive swabs was computed after infection for primary infected children and over the duration of the study for chronically infected children and mothers.
^eChronic infection in secondary children was assumed for all children not meeting criteria for primary infection and not classified as uninfected. Two secondary children were uninfected with CMV, 13 uninfected with HSV, and 8 uninfected with HHV-6; these children were excluded from analyses of these viruses and do not appear in Table 1. Full classification procedure is given in Supp. Figure 1.
^fAll mothers had serologically-confirmed chronic infection with CMV. All mothers shown in Table 1 had either serologically-confirmed chronic infection with HSV-1 (n = 30) or at least two HSV-1 PCR positive swabs in the absence of serology data (n = 1). Chronic infection with EBV and HHV-6 was assumed for all mothers.
