CDC says gonorrhea is drug-resistant
ATLANTA - The sexually transmitted disease gonorrhea is now among the "superbugs" resistant to common antibiotics, leading U.S. health officials to recommend wider use of a different class of drugs to avert a public health crisis.

"Gonorrhea has now joined the list of other superbugs for which treatment options have become dangerously few," said Dr. Henry Masur, president of the Infectious Disease Society of America. "To make a bad problem even worse, we're also seeing a decline in the development of new antibiotics to treat these infections."

The CDC made the new recommendation after discovering that nearly 7 percent of gonorrhea cases among heterosexual men in a survey of 26 U.S. cities last year were drug-resistant. In 2001, only about 0.6 percent of gonorrhea cases among heterosexual men were drug-resistant.

"That leaves us with a single class of highly effective antibiotics," said Dr. John Douglas Jr., director of the CDC's division of STD prevention. Other experts called the situation perilous.
