Abstract

Anti-infection Handbook is a concise A–Z guide to diagnosis and management of most infectious diseases and related conditions found in Australia and worldwide. The handbook makes it easy to find an infection or a pathogen, and to determine what tests are needed for diagnosis and what antimicrobials should be chosen for the treatment.

  • All-in-one: contains most infections found in Australia and worldwide, with more than 275 infectious diseases and conditions related to bacteria, viruses, fungi, protozoa, parasites and insects
  • A-Z: infections are arranged in alphabetical order for easy searching
  • Immunisation (including travel vaccination): integrated in the relevant diseases and appendices
  • Full eBook on ExpertConsult with print purchase.
