Of the nine AIDS countermeasures discussed in the chapter, the first four -- firing employees with AIDS, banning infected students, mandatory screening in the military, and the selective screening of employees -- are unwarranted on epidemiological as well as on psychosocial grounds. Another countermeasure -- life and health insurance discrimination aimed at excluding single males from coverage on the presumption they may fall into a primary risk group -- commits the fallacy of reasoning from "some" to "all." Such a policy violates the insurance industry's public duty to provide all clients with the opportunity for sound coverage as determined by a fair, medically informed, and evenly applied actuarial standard. The remaining countermeasures discussed -- closing bath houses, criminal prosecution, quarantine, and prenatal counseling -- are eligible for possible adoption under the harm principle, but not without serious qualification. 31 notes.
