  • when the immune system is affected by a cold
  • when the matching virus also infects lung tissue
  • when immune system weakened or secondary infection occurs

5. How does HIV become AIDS?

  • infects T helper by the CD4 receptor and replicates its DNA from RNA using reverse transcriptase, destroys them when it leaves
  • infects T killer by the by the CD4 receptor and replicates its DNA from RNA using reverse transcriptase, destroys them when it leaves
  • infects T helper by the CD4 receptor and replicates its DNA from RNA using reverse transcriptase, lives in T cell forever
