Document Summary

Infection: multiplication of a parasitic organism in or on body. Direct transmission: vertical (before or at birth) or horizontal (after birth) A genome of rna or dna with a protein coat/capsid. Some are fragile (even need transfer of a cell), some are resistant. Tropism (tendency) for particular cells due to receptors. Integrating protein in membrane to incite immune attack. May cause cell lysis or activate the cell. May result in secondary infections (an infection that occurs during or after another infection) The killing of one cell type may result in death of other cells that rely on the killed cell type. May cause cell proliferation or neoplastic transformation. Some remain latent and recrudescence (revival) occurs. Protein produced by a virus-infected cell to prevent viral reproduction in neighbouring cells. Avoidance (quarantine) and acquisition of immunity by vaccination. Vaccine: any preparation that confers immunity to a specific disease.
