Another thing - and this is not at an image you get from the public media - is that PID is remarkably common. In the most recent national survey we have, the National Survey of Family Growth, about 8 % of all American women reported that they’d had an episode of PID treated in their reproductive years. Something that you have to understand about PID is that a certain proportion of it, maybe as much as half, is “silent” – in other words, women don’t realize that they have it. So this is clearly an underestimate. If you think about anything that affects individuals of a reproductive age, young individuals, you don’t see chronic diseases very frequently in that population. So this is a very common and morbid condition.
