Tattoo Infections, Personal Resistance, and Contagious Exposure through Tattooing.

Abstract

Bacterial infection of tattoos remains a common complication. Pyogenic bacteria can cause infections shortly after the tattoo is made. Severity of infection varies from minor to major, ultimately with life-threatening septicemia. Viral infections may be introduced, i.e. HVB, HVC, and HIV. The risk of infection depends on the following triad: microbial pathogen and its aggressiveness, individual resistance of the tattooed, and inoculation and exposures by the tattoo needle and in the tattoo parlor. Some infectious risks can be controlled. Persons with weaknesses can refrain from tattooing. Tattoo parlors and tattooing can be hygienic and clean albeit not sterile; much has improved helped by hygiene guidelines of professional tattooists' organizations and through control instituted by local and national authorities. Tattoo inks remain a potential source of infection difficult to control in a low-priced competitive market operating over the Internet and across national borders. Ten percent of new inks are contaminated with bacteria pathogenic to humans, independent of a claim of 'sterility'. Known brands and established manufacturers are considered safer. Work is in progress aiming at common European standards for tattoo hygiene. Doctors have a role not only in treating tattoo infections but also in reporting cases to the competent authority in their country to support the monitoring of tattoo infections at any time, as an instrument for the authority to detect local outbreaks of tattoo infections early and prevent that new tattoo customers become infected. It is a potential risk of the future that new and very aggressive bacteria not seen in the past may unexpectedly show up in the tattoo scene.
