New numbers from the state show sexually transmitted diseases are on the rise in Alaska. Alaska already has some of the highest rates in the country.

Chlamydia rose half a percent from 2015 to 2016, with about 5,700 new cases reported. Of those cases, 79 percent are from people under the age of 29. Chlamydia is the most common STD in the nation, and Alaska has the highest infection rate in the country.

Gonorrhea infection rates saw a significant uptick of 31 percent from 2015 to 2016, when the state saw 197 cases per 100,000 people for a total of 1,454 new cases. Northern Alaska and the Gulf of Alaska coast were the only places that did not see an increase.

There's better news in the fight against syphilis. After a spike in 2014, Alaska's syphilis rate is down from 2012. Just 20 cases were reported last year. That's down from 40 in 2014.
