Communicable diseases are major global health concerns that can devastate whole populations. This revised and updated textbook examines communicable diseases at the community level from an epidemiological perspective, covering both theory and practice in a systematic and globally comprehensive overview of communicable diseases and their control. It includes expanded coverage of epidemiology and clinical aspects, many summary tables and coverage of both developed and developing countries from tuberculosis and malaria to bioterrorism and hospital infections, drawing on the author's personal experience of working in many global locations.
