Globally, action to prevent HIV spread is inadequate. Over 16,000 new infections occur every day. Yet we are not helpless in the face of disaster, as shown by the rich prevention experience analyzed in this valuable new compendium. "Best pr- tice" exists-a set of tried and tested ways of slowing the spread of HIV, of persuading and enabling people to protect themselves and others from the virus. Individually, features of best practice can be found almost everywhere. The tragedy, on a world scale, is that prevention is spotty, not comprehensive; the measures are not being applied on anywhere near the scale needed, or with the right focus or synergy. The national response may concentrate solely on sex workers, for example. Elsewhere, efforts may go into school education for the young, but ignore the risks and vulnerability of men who have sex with men. Action may be patchy geographically. AIDS prevention may not benefit from adequate commitment from all parts and sectors of society, compromising the sustainability of the response. In some countries matters are still worse-there is still hardly any action at all against AIDS and scarcely any effort to make HIV visible. It is no wonder that the epidemic is still emerging and in some places is altogether out of control.

This comprehensive and user-friendly volume focuses on the intersection between the fields of nutrition and infectious disease. It highlights the importance of nutritional status in infectious disease outcomes, and the need to recognize the role that nutrition plays in altering the risk of exposure and susceptibility to infection, the severity of the disease, and the effectiveness of treatment. Split into four parts, section one begins with a conceptual model linking nutritional status and infectious diseases, followed by primers on nutrition and immune function, that can serve as resources for students, researchers and practitioners. Section two provides accessible overviews of major categories of pathogens and is intended to be used as antecedents of pathogen-focused subsequent chapters, as well as to serve as discrete educational resources for students, researchers, and practitioners. The third section includes five in-depth case studies on specific infectious diseases where nutrition-infection interactions have been extensively explored: diarrheal and enteric disease, HIV and tuberculosis, arboviruses, malaria, and soil-transmitted helminths. The final section addresses cross-cutting topics such as drug-nutrient interactions, co-infections, and nutrition, infection, and climate change and then concludes by consolidating relevant clinical and public health approaches to addressing infection in the context of nutrition, and thus providing a sharp focus on the clinical relevance of the intersection between nutrition and infection Written by experts in the field, Nutrition and Infectious Diseases will be a go to resource and guide for immunologists, clinical pathologists, sociologists, epidemiologists, nutritionists, and all health care professionals managing and treating patients with infectious diseases.
