I wasn't accusing you of making it up--I was questioning the WHO.
I posted this on another threat, but I copied it here to help provide some clarification on the "1/3" statistic:
This is true, and few people know it. It's important to draw a distinction here, however. This doesn't mean that 1/3 of the population is sick with TB disease, which is infectious and can be passed to others. What it means is that 1/3 of the world's population is infected with the TB bacillus, which doesn't involve symptoms and can't be passed to others. Roughly 10% of these will develop active disease at some point in their lives, at which point they can then pass the germ to others, each of whom on average would have a 10% lifetime chance of developing TB disease, and so on.
The depletion of the immune system that follows HIV infection, however, increases the chances of developing TB disease to 10% EACH YEAR after TB infection. This is why Africa and Southeast Asia (areas hit hardest by HIV) have seen skyrocketing rates of TB since the 1980s. The two diseases work in tandem--like gasoline and a match.
