Background: Prisoners in French Guiana, a French territory located in South America, have a HIV and hepatitis B prevalence of 4%. Body modifications such as penile implants, tattoos, and body piercings are common among detainees, increasing the risk of blood-borne virus transmission.
Methods: We conducted a cross-sectional randomised survey in which the primary objective was to estimate the prevalence of high risk 'bloody practices' (penile implants, tattoos, body piercings) in French Guiana's only correctional facility.
