The WHO shift to the new class of antibiotics will not fix that overall problem of bacterial creativity. In some countries, strains of gonorrhea are already resistant to the newly recommended class of drugs.
The U.S. Centers for Disease Control and Prevention warned back in 2012 that one of two drugs in the class of antibiotics the WHO now recommends, cephalosporins, was in danger of becoming useless to treat gonorrhea, at least in the U.S, and recommended that doctors stop prescribing it.
Since then, the CDC's recommended treatment for gonorrhea has been a dual therapy, with the two antibiotics ceftriaxone and azithromycin, but an analysis in July warned that the bacteria could even become resistant to that combination.
