  This Health Alert Network (HAN) Update provides current recommendations on management and reporting of Shigella infections that have been treated with ciprofloxacin or azithromycin and resulted in possible clinical treatment failure. This is a follow-up to HAN 401: CDC Recommendations for Diagnosing and Managing Shigella Strains with Possible Reduced Susceptibility to Ciprofloxacin.
  
  The Centers for Disease Control and Prevention (CDC) continues to identify an increasing number of Shigella isolates that test within the susceptible range for the fluoroquinolone antibiotic ciprofloxacin (minimum inhibitory concentration [MIC] values of 0.12-1 μg/mL), but harbor one or more resistance mechanisms. CDC remains concerned about potential clinical failures with fluoroquinolone treatment.
  
  Clinicians should carefully monitor patients with Shigella infections who require fluoroquinolone treatment and report any possible treatment failures. If treatment failure is suspected, clinicians should submit a stool specimen for antimicrobial susceptibility testing, and consider consulting an infectious disease specialist to identify best treatment options.
  
  CDC has also identified an increasing number of Shigella isolates with azithromycin MICs that exceed the epidemiological cutoff value (ECV), and is requesting reports of any possible treatment failures occurring among patients with Shigella infections treated with azithromycin (see below).
  
  Shigellosis is a nationally notifiable condition; all cases should be reported to local health departments.
