viral structure
Viral Structure
  • Nucleic Acid
    • DNA or RNA
  • Capsid (protein coat)
viral structure1
Viral Structure
  • Envelope
    • Forms when virus takes host membrane with it upon release
how virulent viruses work
How Virulent Viruses Work
  • Attachment
  • Entry
  • Replication
  • Assembly
  • Release (Lysis)

Lytic Cycle

how temperate viruses work
How Temperate Viruses Work
  • Attachment

Lysogenic Cycle

viral pathology
Viral Pathology
  • Influenza
    • Respiratory tract
  • Acquired Immunodeficiency Syndrome
    • Attacks immune system leaving victim vulnerable
  • Cancer
    • Some viruses mutate DNA to upset cell cycle
treatment
Treatment
  • Vaccines
    • Virus unable to replicate in host
  • Antiviral Drugs
    • Inhibit nucleic acid synthesis
    • Inhibit capsid synthesis
