Gonorrhea is showing resistance to all but one antibiotic drug used against it, U.S. health officials announced this week.

“We’re trying to sound the alarm to prevent untreatable gonorrhea from becoming a reality,” said Gail Bolan, director of the Division of STD Prevention at the Centers for Disease Control and Prevention. “We’re very concerned.”

An estimated 700,000 cases of gonorrhea occur in the United States each year, with fewer than half of them being reported. It is one of the most common STDs. Rates are highest among African-Americans and sexually active teenagers and young adults.
