Abstract The Internet is an emerging venue for facilitating high-risk sexual behavior; in
particular, use of the Internet to seek out sex partners has been shown to be associated with highrisk sexual behaviors, such as an increase in number of sexual partners and an increase in anal sex,
which can increase the risk of contracting and transmitting sexually transmitted diseases (STDs)
including HIV. In an effort to assist health departments around the country, the Internet Alert Project
was developed to provide Centers for Disease Control and Prevention (CDC) project officers and field
staff with information about Internet-advertised,

high-risk sexual activities in areas that do not have
access to sexually explicit material on the Internet. An evaluation was conducted to determine the
utility of the Internet Alert Project, its effect on knowledge and awareness of recipients and on public
health efforts. Results of the evaluation show the alerts are a useful and valuable tool. The alerts have
helped to increase knowledge about sexually-related uses of the Internet and have also driven public
health efforts in the field. The results also indicate the need for project areas to access information found
on the Internet in order to keep up with the ever-changing behaviors of at-risk populations.
Introduction
Every year, more and more Americans use the Internet for various reasons from seeking basic
information on health care (Madden, 2003) to locating sex partners (Klausner et al., 2000).
Use of the Internet to seek out sexual relationships has been documented since the late 1990s
(Cooper, 1998), and includes various types of sexual relationships from long-term,
monogamous relationships to frequent, anonymous, one-time sex acts (Bull & McFarlane,
2000). By 2000, the Internet was recognized as a new risk environment for STD/HIV, and
those who used the Internet to seek sex partners appeared to be at higher risk for STDs than
those who did not seek sex partners on the Internet (McFarlane et al., 2000). People using the
Internet to find sex partners are very diverse and include men who have sex with men (Elford
et al., 2001; Kim et al., 2001), couples seeking other couples (Jenks, 1998), women (Kachur
et al., 2002; Leiblum, 2001) and adolescents (McFarlane et al., 2002).
