In Phase I, the proportion of participants who are willing to undergo rapid HIV testing in the ED will be measured. Additionally, the HIV testing history of these participants, their reasons for undergoing testing or for never having been tested for HIV, and factors associated with acceptance or decline of testing and history of HIV testing will be determined. An educational video will be developed and used to investigate its effectiveness in convincing participants to have the rapid HIV test. All participants agreeing to undergo a rapid HIV test will receive a survey to complete.
