Three more cases of measles have been confirmed in Sedgwick County, and officials say they expect more cases to emerge through August.

The Wichita Eagle reports the Kansas Department of Health and Environment announced the new cases on Tuesday, bringing the total in the county to 11.

Preston Goering, director of the county’s Preventative Health division, told county commissioners on Tuesday that the department’s staff has been going to several homes to take temperatures and check for symptoms when someone has been exposed.

KDHE spokeswoman Aimee Rosenow says the soonest the current outbreak can be considered over is the end of August.

Measles were thought to have been eliminated decades ago, but foreign travel and the refusal by some to vaccinate have caused the ailment to re-emerge.
