 The incidence of "M. abscessus" infections appears to be increasing over time.Outbreaks of "M. abscessus" have been reported in hospitals and clinical settings worldwide.While outbreaks of major clinical concern involve transmission (most likely indirect transmission) between vulnerable patients such as those receiving lung transplants or being treated for cystic fibrosis, outbreaks have also been reported at clinics providing cosmetic surgery, liposuction, mesotherapy and IV infusion of cell therapy, although these are more attributable to contaminated disinfectants, saline and instruments than contact between patients.
