Yeah, with regen if you lose one hp each year you can still get afflictions, however there is some evidence that this is at a reduced chance. Some say that regen gives 75% chance of not getting afflictions{{verify}}.

But Bullock, there is a reason you want a dome up as soon as possible on your cap. Prevents this kinds of nasty ****. Domes are also pretty hard to detect without casting spells. The other way is by attacking the province. (Both methods tend to alarm your enemy of your intent, I think domes tell you when they stop a spell, and a lone scout attacking your cap out of the blue, is a indication of a possible attack). And if you get a regular amount of castable random events at your cap, it is usually another player casting them.
