Viruses
Classification: Reproduction: Structure: Disease eg: Treatment/ cure:
Non-living Requires a host cell Tiny - only seen by HIV/AIDS General:
∴ not in any electron microscope (retrovirus, converts RNA to DNA
of the five Viruses are tissue specific before) Can’t be killed by antibiotics
kingdoms (glycoproteins attach to Protein coat - caspid ∵ non-living
specific receptors on 🠖protects nucleic acid Infects cells with CD4
host) receptors(macrophages and T-helper Glycoproteins act as antigens
Genetic material cells) and trigger immune response
Genetic material from 🠖nucleic acid
host and virus combine (DNA/RNA) viruses form part of virus envelope using 🠖Acquired immunity
host cell covering (camouflaged) (from vaccine)
Use hosts metabolic Glycoprotein:
processes to duplicate 🠖attaches to host Viruses continue mutating 🠖Natural immunity
nucleic acid and protein receptor (from exposure)
coat(caspid) Body fights viral load and makes
Sometimes has: antibodies HIV/AIDS:
(can become dormant at (no symptoms at this point)
this stage) Viral envelope No cure
As more CD4 cells are made to fight the
Cellular activity virus, the more HI viruses produced ARV’s slow progression
assembles new viruses- (symptoms)
host cell bursts realeasing ART prevent new viruses
new viruses Low immune system can no longer fight being made
the virus
Progressed to AIDS
(opportunistic infections eg: TB)
Symptoms:
Fever, sweats, aching joints, swollen
lymph nodes
Transmission:
, (blood, semen, vaginal fluid, breast milk)
1) Sexual intercourse
2) Mother to child
3) Intravenous drug usage/sharing
sharp objects
