Routine testing in other circumstances will evolve from voluntary and required testing. A review of the common arguments against mandatory or required HIV testing confirms the importance of alleviating the concerns of those who oppose mandatory testing. The two greatest obstacles are concerns about confidentiality and fear of quarantine. To ensure confidentiality, everything possible must be done to improve records systems. To reduce society's disposition to isolate those infected with the HIV, society must be taught that those ill with AIDS warrant compassion, care, and respect. Mandatory or required testing under certain circumstances, such as in the diagnosis of various symptoms that might be related to AIDS, incorporates all the virtues of voluntary testing without the drawbacks. There would be widespread voluntary compliance with required testing just as there is for blood counts and tuberculin tests once it becomes widely recognized as a health issue for the benefit of all involved rather than an attempt to target persons for adverse treatment.
