The commercial sex industry, transactional sex, and sex tourism in the Caribbean are likewise important factors. HIV infection rates for commercial sex workers are high, ranging from 4.5-12.4 percent in the Dominican Republic (2000) to 9 percent in Jamaica (2005) to 30.6 percent in Guyana (2000). One possible explanation is that the use of condoms in transactional sex is less likely. In addition to the specific industry of sex tourism, studies have shown that the general tourism industry is positively correlated with the HIV epidemic. The perceived connection exists in that there are aspects of the environment of a tourist area that foster higher risks for HIV infection. These include riskier behaviors on the part of locals and tourists, as well as employees of the tourism industry engaging in relations with the tourists.
