Should laws allow the maintenance of databases of names of those who have a communicable, incurable disease?

Pro: A database that reveals the identities of those who have communicable diseases can help authorities maintain public health.

Con: The maintenance and use of such a database would not ensure that the public would be safe from the threat of communicable diseases. The existence of such a database may give authorities a false sense that the public faces no risk of disease spreading. An official could not conclude that a particular individual whose name is not on list is free from disease.
