Summary of Nanjing single-centre experience of mother-to-infant transmission of hepatitis B virus (HBV) versus HBV prophylaxis failure rate

Maternal HBV DNA level at delivery*	Infection rate, n/n (%)
<6 log10 copies/mL	0/0 (0)
6–6.99 log10 copies/mL (2×5–6 log10 IU/mL)	9/298 (3.2)
7–7.99 log10 copies/mL (2×6–7 log10 IU/mL)	29/531 (5.46)
>8 log10 copies/mL (2×7–8 log10 IU/mL)	23/239 (9.62)

^*1 IU/mL = approximately five virus genome copies (or virus genome equivalents)/mL. Data from reference 198
