Since the publication of the first edition of this handbook, prevention of occupational transmission of infectious diseases has become a much greater concern for an even broader range of workers. Newly revised, updated, and expanded, the third edition of this publication is intended to be a practical hands-on reference for all professionals concerned with preventing the occupational transmission of infectious diseases. As a result of the September 11th terrorist attacks on America, attention is now focused on the real threat of bioterrorist warfare. The now infamous anthrax disease, smallpox organism, and West Nile Virus disease are discussed in this edition. Recognition of these and other diseases, modes of transmission, symptoms, protective/preventative measures, post-exposure follow-up, and engineering controls are discussed. Information is presented in an outline format for easy use.
