HIV (retrovirus)
TreatmentVaccines
Virus unable to replicate in host
Antiviral Drugs Inhibit nucleic acid
synthesis Inhibit capsid
synthesis
Viral EmergenceMutation from existing viruses
Influenza
Viral EmergenceInterspecific infection
Hantavirus from rodents
Viral EmergenceSpread from formerly isolated location - Ebola
Subviral ParticlesViroids Infectious RNA disrupts metabolism in plants
Prions Misfolded proteins misfold normal proteins in
animals
Review Questions1.What materials are found in every virus?2.How do viroids and prions vary from
virions?3.What are effective ways to combat
retroviruses?4.How might new viruses emerge?
