Maybe it's in the article and I'm missing it, but can anyone cite what the WHO considers "eliminate" to mean in this context? All I see is that in 2013 two babies were born with HIV (though seeing as mother-to-baby appears to include from breastfeeding, I'm not sure that number is the full picture). Does eliminate mean there was a single year (2014 I guess) with no mother-to-baby transmission?
The reason I'm curious is because just because this year there are no cases, doesn't mean there won't be next year. So I wonder what the definition they're using is.
