1Expert Panel on HIV Infection of Health Care Workers (2009-2012), Hong Kong SAR, China.
Abstract:
We report the referral of an HIV-infected surgeon and a subsequent first-ever recommended look-back investigation in Hong Kong. Efficient coordination and effective implementation of the look-back investigation yielded a high response rate of 92.3% of priority patients, with none tested HIV positive. Our experience reconfirmed the very small risk of provider-to-patient HIV transmission and the crucial importance of infection control.
