North Dakota’s on a pace to set a new record for sexually transmitted diseases in 2012. The state health department has confirmed one-thousand-381 cases of chlamydia during the first six months of the year -- up nearly 200 from the same time in 2011. STD coordinator Sarah Weninger says increased screening…a larger population…and greater awareness may be behind the bump. 70-percent of s-t-d cases occur in the 15 to 24 year age group. The department says the 136 cases of gonorrhea is also up slightly.
