For a couple of weeks, Etowah County, Ala., had the nation’s highest rates of sexually transmitted diseases by a country mile. It was the first time in more than a decade that St. Louis wasn’t ranked at the top for chlamydia and gonorrhea.

Turns out it was a mistake.

The Alabama Department of Public Health released updated, much lower numbers that knock Etowah County out of the top slot, returning St. Louis to the top ranking.

A new surveillance system adopted by the department in late 2016 contributed to the error, according to Dr. Burnestine Taylor. Taylor could not be reached Monday. The department and the Centers for Disease Control and Prevention, which tracks the national rankings, were closed Monday for Columbus Day.
