Abstract

Communicable diseases, especially those that are readily contagious, are on the rise as evidenced by the emergence of viruses like severe acute respiratory syndrome, the global resurgence of resistant forms of ancient mycobacteria such as extensively drug resistant tuberculosis, and the 2009 swine flu outbreak in Mexico. Moreover, each of us, no matter who we are or where we live, is just as likely to transmit contagious diseases to others as we are to contract such diseases from others. As cogently described in the title of a recent book by Margaret Battin et al., we are all potential “victims and vectors.”Just as contagious diseases are readily passed person to person, so too can they readily be passed across local and national boundaries. We therefore all have a stake in the development of effective infectious disease control policies on a national scale, with “effective” being the operative term: regulations and statutes that are neither enforceable nor likely to be complied with may do more harm than good.
