Infectious diseases once considered vanquished in the developed world now represent a growing challenge to public health care systems. Not only do we face threats from new diseases, such as AIDS, MRSA, SARS and Avian Flu, but old scourges, such as tuberculosis are returning in drug resistant forms. Food-borne infections are common, encompassing both common bacterial infections that are associated with gastro-enteritis and new diseases that have crossed the species barriers, such as BSE and the resultant new variant CJD. SARS and Avian Flu are the newest threats and have an increasingly high public profile. These diseases present complex and as yet unresolved problems for those involved in the control of infectious disease. Jennifer Roberts and her international team present the contribution economists can make to the management and control of infectious diseases. The book leads the reader through the economic evaluation of specific diseases, chosen to reflect some of the great challenges to those aiming to control infectious disease in both developed and developing countries.
