1. Infectious Disease Types

Key Concepts & Definitions

  • Pathogen: A microorganism (bacteria, virus, fungi, or parasite) capable of causing disease in a host.
  • Bacteria: Single-celled prokaryotic organisms that can be pathogenic or beneficial; cause diseases like pneumonia and food poisoning.
  • Virus: A non-cellular infectious agent that requires a host cell to replicate; causes illnesses such as influenza and HIV.
  • Fungi: Eukaryotic organisms, including yeasts and molds, that can cause infections like candidiasis and aspergillosis.
  • Parasites: Organisms that live on or inside a host, deriving nutrients at the host's expense; examples include Plasmodium (malaria) and Giardia.
  • Zoonosis: An infectious disease transmitted from animals to humans, accounting for a significant portion of emerging infections.
