(CNN) Gonorrhea is becoming harder and in some cases impossible to treat with antibiotics, the World Health Organization said. Every time we use a new class of antibiotics to treat the infection, the bacteria evolve to resist them," said Teodora Wi, a human reproduction specialist at the WHO, in a news release. Marc Sprenger, WHO's director of antimicrobial resistance, said there's an urgent need for drugs and tests to prevent, diagnose and treat gonorrhea. Gonorrhea has developed resistance to nearly every class of antibiotics used to treat it such as penicillin, tetracycline and fluoroquinolones, the CDC said. But most people who are infected do not have any symptoms and in some cases, doctors mistakenly diagnose gonorrhea, health officials said.
