Outbreak of Sexually Transmitted Nongroupable <i>Neisseria meningitidis</i>–Associated Urethritis, Vietnam

Abstract

We report on an outbreak of nongroupable Neisseria meningitidis-associated urethritis, primarily among men who have sex with men in southern Vietnam. Nearly 50% of N. meningitidis isolates were resistant to ciprofloxacin. This emerging pathogen should be considered in the differential diagnosis and management of urethritis.
