If mother has undetectable viral load from conception to birth, HIV is untransmittable.
The risk of vertical HIV transmission – from mother to child during pregnancy or delivery – is zero when a mother has a fully suppressed viral load from the time of conception until after giving birth, an analysis combining 138 studies and 82,723 month-infant pairs has concluded.
The analysis found that if viral load is above 50 copies but below 1000 copies during pregnancy, the risk of vertical transmission is approximately one in 77 – in other words, for every 77 pregnancies where viral load is detectable but below 1000 copies, one will result in vertical HIV transmission.
The study by Dr Caitlin Dugdale of Harvard University and colleagues is published in The Lancet.
