Doctors are warning of a new sexually-transmitted superbug that they say could ultimately prove more deadly than AIDS.

The antibiotic-resistant strain of gonorrhea HO41 was reportedly discovered in Japan two years ago in a 31-year-old female sex worker.

“This might be a lot worse than AIDS in the short run because the bacteria is more aggressive and will affect more people quickly,” Alan Christianson, a doctor of naturopathic medicine, recently told CNBC. “Getting gonorrhea from this strain might put someone into septic shock and death in a matter of days. This is very dangerous.”

Reportedly added William Smith, executive director of the National Coalition of STD Directors: “It’s an emergency situation. As time moves on, it’s getting more hazardous.”
