This article explores the issue on student HIV testing in Wisconsin. Wisconsin has enacted what appears to be the nation's first law requiring students to be tested for HIV, if teachers or other school employees can prove they were significantly exposed to the students' blood while on the job. The law, which critics view as an unwarranted intrusion on privacy, gives employees of Wisconsin public and private schools the same rights as emergency personnel, medical workers, correctional officers, and group-home workers to require blood tests under comparable circumstances. Even though various groups and activists criticize the new law, resource-center officials believe that testing the person who came in contact with the blood is the only foolproof way to determine if a person was infected.
