Thanks to Dr. Ian Mackay for tweeting about this issue. Via Emerging Infectious Diseases: Ahead of Print - Self-Flagellation as Possible Route of Human T-Cell Lymphotropic Virus Type-1 Transmission. The abstract:
We report human T-cell lymphotropic virus type-1 infection associated with self-flagellation in 10 UK residents. These persons were heterosexual men from Pakistan, India, and Iraq. One person showed seroconversion in adulthood; 1 was co-infected with hepatitis C virus. No other risk factors for bloodborne virus acquisition were identified. Onward sexual transmission has occurred.
