SARS, West Nile Virus, Avian Flu, and bioterrorism-related Anthrax are among the many infectious diseases that dominate the discussion among public health officials and policy makers today. This timely revision of Infectious Disease Epidemiology  has been thoroughly updated to cover these and many other contemporary issues in infectious diseases.   Updates include four new chapters on Immunology, Measles, Meningococcal Disease, and Vector-borne infections. The HIV chapter has been substantially expanded to include issues of Host Genetics as well as a review of behavioral interventions. Special attention has been given To The overlapping epidemics of HIV/AIDS, Tuberculosis, and Malaria in Sub-Saharan Africa, including a description of the activity and funding for these neglected crises. The authors have also included some basic information from the disciplines of molecular biology, immunology, and human behavior to help the epidemiologist design or evaluate programs to control infectious diseases.   This comprehensive, reader-friendly text is an essential resource for both students and professionals of infectious disease epidemiology.
