SALINA, Kan. (AP) — Health officials say Saline County is dealing with an outbreak of syphilis.

The Salina Journal reports that through June of this year Saline County did not have any reported cases of syphilis. But Jason Tiller, coordinator for the Saline County Health Department, says that in the past 75 days more than 11 cases have been reported in the county.

Tiller told Saline County commissioners Tuesday that officials think more cases of syphilis are going undiagnosed, and the department is trying to raise awareness.

Tiller says syphilis is a bacterial infection spread through sexual contact, and is easily treatable with antibiotics during the first year after infection. It can be treated later, but it’s more difficult to treat.
