A narrative review of infections associated with personal service establishments Part II: Piercing and tattooing
In part II of our paper on personal service establishment services-related infections, we review bacterial, viral, and fungal infections related to piercing, tattooing, and body modification. Sixty-six studies were identified for piercing and tattooing-related viral and bacterial infections. No studies investigating fungal infections, or body modification service-related infections were identified. Bacterial infections, particularly, mycobacterium infections were commonly reported for piercing and tattooing, while viral risks were less well characterized, with the exception of tattooing related hepatitis B and C infections. Aside from localized infections at the pierced or tattooed site, a systemic infection involving the outer lining of the heart, infective endocarditis (IE), was also identified as an important health concern; those with pre-existing heart conditions are at highest risk of IE from invasive procedures. Both bacterial and viral outbreaks were linked to poor infection control procedures, and in two events, the use of municipal water to dilute tattoo ink was suspected as a source of mycobacteria leading to outbreaks of infection. The majority of studies identified were case reports; these studies provide only a limited understanding of infection pathways and do not allow for a quantitative estimation of risk. Despite important gaps in current knowledge, the available scientific literature can be used to support and inform the development of health-protective policies and practices in personal service establishments.
