Before 1993, the total number of HIV infections was under 500. The first 5-years national strategic plan for prevention and control of HIV/AIDS initiated in 1994 focused on disease surveillance and health education (Taiwan Department of Health [DOH] 2006) . Currently, the Department of Health is implementing the fourth national strategic plan (2007) (2008) (2009) (2010) (2011) . The plan's three major goals are preventing and controlling HIV infection, encouraging the use of screening and counseling to modify risky behaviours, and providing appropriate health care for infected people to improve their quality of life (Taiwan DOH 2006, p. 21) .
