From what I could find via HIV Norway, nine men and three women have been convicted in accordance to Paragraph 155 (the paragraph stems from 1994, but was amended in 2003 to demand condom-use by persons infected with sexually transmitted diseases [the key one: HIV). Five of the cases include a spread of HIV, presumably by the convicted defendant. Their punishments range from 120 days to two years and ten months (it looks like those who inform their partner of their infection usually receive a lesser sentence than those who do not).
Recently, a sauna/bathhouse-owner in Bergen was charged under this paragraph and for, in effect, pimping out one of the worker's there (who is HIV-positive). It was the worker who brought the complaint to the police, so it'll be interesting to see what comes of this.
