Global: How reliable is an undetectable viral load?

Interesting new data from Switzerland about how reliably you can count on having an undetectable viral load between clinic visits has just been reported on aidsmap.com.

Overall, there was a 98% probability that viral load would not rebound from undetectable to the potentially infectious level of 1000 copies/ml or above in successive tests. If an individual had started HIV treatment with a triple combination of drugs this increased to 99%.
This is very helpful for those arguing that HIV exposure is extremely unlikely if someone takes triple combination therapy (the current standard), has 100% adherence and no other sexually transmitted infection.
